2. Work PrecautionsInspection

If you discover any defects or problems during an inspection, fix the problems or if necessary takesteps such as replacing a part.

RemovalCheck the problem area. At the same time, examine the cause of the problem and determinewhether the part needs to be removed or disassembled. Next proceed according to the proce-dures presented in the Technical Manual. In cases where, for example, it is necessary to disas-semble areas with large numbers of parts, parts which are similar to each other, or parts which arethe same on the left and right, sort the parts so that you do not mix them up during reassembly.(1) Carefully sort the removed parts.(2) Distinguish between parts which are being replaced and those which will be reused.(3) When replacing screws, etc., be sure to use the

specified sizes.

Assembly and InstallationUnless specified otherwise, perform the removal proce-dures in reverse during assembly and installation. Incases where protrusions or holes are provided to assistin positioning parts, use them for accurate positioningand securing.(Protrusions and holes for positioning parts Halfpierce section)

ToolsUsing tools other than those specified can lead to injuryor damage screws and parts. Have all the tools neces-sary for the work available.

Electrical system work• After removing wire bundles, fasten them

with wire bundle bands (bar lock ties) sothat they will not sag.

• When installing parts, be careful to avoidpinching or damaging the wire bundles.

• If a fuse blows, always replace it with onewith the specified capacity. Using a fusewith a larger capacity can not only dam-age parts, but may cause fires.

• Be careful not to drop image scanners,thermal print heads, and other sensorsas they can be easily damaged.

Switch types• Microswitches may be divided between nor-

mally open (NO) types and normally closed(NC) types.With an NO connection, an internal con-tact is connected when the switch actua-tor is pressed.With an NC connection, an internal con-tact is disconnected when the switch ac-tuator is pressed.

• Magnetic lead switches are switches inwhich an internal contact is connectedin reaction to the magnetic force of amagnet.

Sensor types• Photo-electric sensors may be broadly

divided into the following four types: in-terrupt types (U-shaped), actuator types,reflective types, and transmittive types.

• Magnetic sensors use Hall ICs, which re-act to the magnetic force in magnets.

• Always turn off the power before pluggingor unplugging sensor connectors.

WORK PRECAUTIONS



Installation location• Do not install the machine in any of the following locations.(1) Those subject to direct sunlight or any bright location such as by a window (If you must

install in such a location, put a curtain or the like over the window.)(2) Those where the temperature changes drastically(3) Those that are too hot, cold, humid, or dry

RECOMMENDED:Temperature range: 15° centigrade - 30° centigradeHumidity range: 40% - 70% No condensation allowed

(4) Those with radiant heat sources and any locations in the direct path of air from air condition-ers, heaters

(5) Any poorly ventilated location(6) Dusty atmosphere(7) Any tilted location

(Installation height difference: 10 mm max. front - rear, 10 mm max. left - right)

Electrical connection• Plug the plug securely into the socket so that there is no problem with the contact in the power

supply plug section.• Do not use any triplets or extension cords.• Do not allow any other machine to stand on or crush the power cord.

Ground connection• Always ground this machine to prevent electrical shock in the unlikely event of electrical

leakage.

B: Adjustment dial

C: Paper size detection sensor

D: Paper width potentiometer

Mechanism

1. Paper Feed Tray Mechanism

1) Horizontal positioning (horizontal print positioning) of the paper feed trayThe Paper feed tray [A] can be moved ±10 mm left or right by turning the Adjustment dial [B] manually(for paper widths up to 274 mm, and ±5 mm for paper widths between 275 mm and 290 mm).

2) Print paper size detectionThe Paper feed tray [A] uses the Paper width potentiometer [D] and Paper size detection sensor [C] todetermine the size of the paper loaded in the Paper feed tray [A].

The Paper width potentiometer [D] checks the paper width, and the Paper size detection sensor [C]determines the paper length (portrait or landscape orientation).

D

View of underside of the paper feed traywith the cover off



PAPER FEED TRAY ELEVATION MECHANISM

2. Paper Feed Tray Elevation Mechanism

The presence of paper loaded in the Paper feed tray [A] is detected by the Paper detection sensor [B].

When light is received at the Paper detection sensor [B] (paper present), pressing the START keyactivates the Elevator motor [E] and raises the Paper feed tray [A] until the Scraper assembly [C] blocksthe light beam of the Upper limit sensor [D].

During printing, the Elevator motor [E] is activated until the light to the upper limit sensor [D] is blocked.

When there is no longer paper in the Paper feed tray [A] and light is not received by the Paper detectionsensor [B], the Elevator motor [E] activates and lowers the Paper feed tray [A] until the light beam of theLower limit sensor [F] is blocked.

If the Feed tray descent button [G] is pressed while in print standby mode, the Elevator motor [E] activatesand lowers the Paper feed tray [A] until either the light beam of the Lower limit sensor [F] is blocked or theFeed tray descent button [G] is pressed once again.

The Elevator motor [E] does not operate even if the Feed tray descent button [G] is pressed while the printdrum is removed.

FIRST PAPER FEED DRIVE MECHANISM

4. First Paper Feed Drive Mechanism

When the printing operation commences, the Main motor [A] activates to rotate the print drum via the Mainbelt [C]. When the Main motor [A] is running, the Paper feed timing belt [D] continuously drives the pulleyon the Paper feed clutch [E].

When the print drum rotates through a preset angle (the angle set for paper feed clutch activation by testmode No. 481) from position A, the Paper feed clutch [E] is activated. The Scraper roller [G] and Pickuproller [H] rotate to feed the paper inside the machine from the paper feed tray.

The paper fed inside the machine blocks the light beam between Paper sensors [I] and [L]. The printdrum then rotates through a preset angle (the angle set for paper feed clutch deactivation angleadjustment by test mode Nos. 482 to 485), and the Paper feed clutch [E] is deactivated, completing thefirst stage paper feed.

The leading edge of the paper rests against the Guide roller [J] and Timing roller [M] and stops with thepaper bulging.

If the print drum rotates as far as the first paper feed jam detection angle after the Paper feed clutch [E]has been activated, Paper sensors [I] and [L] check to detect the presence or absence of paper.

After the paper has been fed to the second paper feed stage, a one-way clutch acts on the Scraper roller[G] and Pickup roller [H] so that they spin, to prevent the first paper feed area from applying brake on thepaper.

PAPER STRIP MECHANISM

5. Paper Strip Mechanism

The paper loaded in the paper feed tray is fed in between the Pickup roller [A] and Stripper pad [B] by therotating scraper roller. The paper is then separated by the Pickup roller [A] and Stripper pad [B] to ensurethat only the uppermost sheet is sent into the machine.

The Stripper pad [B] is pressed against the Pickup roller [A] by the force of the Stripper spring [C], and theresistance applied to the paper fed in separates the sheet.

The stripper-pad angle and stripping pressure can be adjusted by the user using the Stripper pad angleadjust knob [D] and Stripper pressure adjust knob[E].

PAPER FEED PRESSURE ADJUST LEVER

6. Paper Feed Pressure Adjust Lever

The Paper feed pressure adjust lever [A] is located on the left-hand side of the scraper unit, and movingthis to the left or right switches the scraper-roller paper-feed pressure (scraper pressure) from NORMAL(weak) and CARD (strong).

Moving the pressure adjust lever to the right increases the paper-feed pressure (scraper pressure).

SECOND PAPER FEED MECHANISM

Mechanism

1. Second Paper Feed Mechanism

When the main motor operates during printing, the Main cam [A] rotates clockwise.

The Main cam [A] rotation moves the Timing gear [C] via the Cam follower arm [B], and this rotates theTiming cam [D].

The Timing cam [D] contains a one-way clutch, so that when it rotates counter-clockwise, the rotation istransferred to the Timing roller [G], but when it rotates clockwise, the rotation is not transferred.

The Load spring [H] continuously applies a load to the Timing roller [G] to ensure that the Timing roller [G]stops immediately when it is not rotated.

The Timing roller [G] rotation also rotates the Guide roller [F] clockwise.

As the Timing cam [D] rotates, the protrusion pushes against the Timing lever [E] and raises the Guideroller [F].

During printing, the Guide roller [F] moves down and contacts the Timing roller [G] during the first paperfeed operation, and then rises once the Timing roller [G] stops rotating.

SECOND PAPER FEED MECHANISM

Drum Position-A

At Drum position-A, the protrusionon the Timing cam [B] pushesagainst the Timing lever [C] toraise the Guide roller [D].

First paper feed start

When the first paper feed startsand the paper is fed in, the Timinggear [E] is rotated in the direction,indicated by arrow mark, by theMain cam [A]. This rotates theTiming cam [B], which lowers theTiming lever [C] to lower theGuide roller [D].

Second paper feed start

When the first paper feed ends,the Timing gear [E] is rotated bythe Main cam [A] in the directionindicated by the arrow mark. Thisrotates the Timing cam [B] andalso causes the timing roller [D]to rotate, feeding the paper. (TheGuide roller [D] rotates on contactwith the Timing roller [F].)

VERTICAL PRINT POSITIONING MECHANISM

2. Vertical Print Positioning Mechanism

Pressing the < > or < > print position keys on the panel activates the Print positioning pulse motor [A],which rotates the Print positioning adjuster cam [B] to move the Print positioning plate ass’y [C].

The Print positioning plate ass’y [C] motion moves the Print positioning lever ass’y [E], changing thetiming with the main cam.

The second paper feed (timing roller rotation start) timing is thus changed, changing the vertical printingposition.

The Vertical centering sensor [D] checks the centering of the print positioning.

When the < > key is pressed, the print-positioning adjuster cam [C] and print-positioning adjuster plate ass’y [B] move in thedirections indicated by arrows.

The movement of the Print-positioning plateass’y [B] also moves the Print-positioning leverass’y [D], and the bearing [E] in contact with theMain cam [A] moves in the direction indicatedby arrows.

The timing of the contact of the bearing [E]against the Main cam [A] is delayed, causingthe second paper feed timing to delay, andmoves the print position up.

When the < > key is pressed, the Print-positioning cam [C] and Print-positioning plateass’y [B] move in the directions indicated byarrows.

The movement of the Print-positioning plateass’y [B] also moves the Print-positioning leverass’y [D], and the bearing [E] in contact with theMain cam [A] moves in the direction indicatedby arrows.

The timing of the contact of the bearing [E]against the Main cam [A] is advanced, causingthe second paper feed timing to advance, andmoves the print position down.

CHAPTER 6. PRESS SECTION

PRESS MECHANISM

Mechanism

1. Press Mechanism

The main motor activates when printing begins, and the Pressure solenoid [F] activates once the printdrum rotates through 40°.

As the clamp plate base on the print drum approaches the pressure roller, the protrusion on the Pressurecam [A] pushes against Pressure lever A [B] to rotate it clockwise. This rotary motion causes Pressurelever A [B] to push against Pressure lever B [C], and the Solenoid lever [G] separates from Pressure leverB [C] and descends.

Once the protrusion on the Pressure cam [A] has passed, pressure lever A [B] rotates counter-clockwise.Likewise, Pressure lever B [C] is pulled by the tension of the Pressure spring [D] and Second pressurespring [E], and rotates in unison with Pressure lever A [B]. The Pressure shaft [H] fixed to Pressure leverB [C] therefore also rotates counter-clockwise. The pressure roller therefore rises and is pressed againstthe print drum.

During printing, the Pressure cam [A] pushes against Pressure lever A [B] and lowers the pressure rollerto prevent the pressure roller from touching the print drum clamp plate base. The Pressure solenoid [F]remains activated.

After printing is complete, the Pressure solenoid [F] is deactivated when the print drum reaches the 135°position.

PRESSURE CONTROL MECHANISM

2. Pressure Control Mechanism

Pressing the < > or < > print density keys on the panel activates the Pressure control motor [A] andmoves the Print pressure gear ass’y [D]. The movement of the Print pressure gear ass’y [D] varies thetension of the second pressure spring [B].

This alters the pressure acting on Pressure lever B [C], and varies the print density by varying thepressure of the pressure roller against the print drum. The pressure control motor is not actuallyactivated until the START key is pressed.

The printing pressure will vary depending on the printing speed and print density settings, the ink color,the length of time the print drum remains standing, and the print drum’s internal temperature.

The Print pressure control sensor [E] checks the standard printing pressure position.

MOUNTING POSITION OF THE PRESSURE LEVER ASS’Y

Adjustment

1. Mounting Position of the Pressure Lever Ass’y

Checking and adjustment procedure(1) Make a confidential master, and then bring the print drum to position A.


(3) Remove the screws and pull forward the filter PCB unit.

(4) Remove the Second pressure spring, push up the Pressure lever B [A], and disengage it from theSolenoid lever [D].

(5) Attach the Second pressure spring and check that the gap between Pressure lever A [B] andPressure lever B [A] is between 1.5 mm and 2.0 mm. (See detailed figure 2.)

(6) If the gap in step (5) is outside the specifications, remove the Second pressure spring andloosen the two set screws on Pressure lever B [A]. Insert a 3 mm Allen wrench [C] betweenPressure lever A [B] and Pressure lever B [A] (see detailed figure 1), rotate the Pressure shaft [E]fully counter-clockwise, and then tighten the set screws on Pressure lever B [A] with the pressureroller pressing hard against the print drum. The Pressure lever B [A] should be pushed all theway back against the machine, when tightening the set screws.

(7) Check as in step (5), and if the gap is still outside the specifications, repeat step (6). If the gap iswithin the specifications, push Pressure lever B [A] upwards, lock with the Solenoid lever [D], andattach the Second pressure spring.

Symptoms

• If the gap is too small, the pressure will be too weak, and the printing density may become too light.

• If the gap is too large, there will not be sufficient space between the Pressure roller and the Clampplate base on the print drum, and they may touch, damaging the Clamp plate base.

PAPER EJECTION MECHANISM

Mechanism

1. Paper Ejection Mechanism

Printed paper is first detached from the print drum by the Separator [B] and two Separation fans [F]. It isthen sent to the paper receiving tray by the Transfer belts [E].

The transfer belts [E] are driven by the Paper ejection motor [C].

Two Suction fans [D] are located below the Transfer belts [E], and these suck the paper onto the transferbelts [E].

The Paper receiving sensor [A] checks whether the paper is ejected correctly.

The Encoder sensor [G] checks the rotation of the Encoder sensor disc [H] to ensure that the transfer beltspeed is slightly faster than the corresponding print drum rotation speed and ensure smooth paperejection from the print drum.

PAPER SEPARATOR MECHANISM

2. Paper Separator Mechanism

The Separator [A] is close to the print drum when the paper is being detached from the print drum. As theprint drum rotates and the clamp plate base approaches the Separator [A], the Separator arm ass’y [G] ispushed by the Pressure cam [F] on the Print drum pulley. This also pushes the Separator lever [H], andthe Separation shaft [B] rotates, causing the Separator [A] to move away from the print drum.

Likewise, when pulling out the print drum, the Release lever [D] is returned by the Release lever spring[E]. And when the Release arm [C] is pressed, the Separation shaft [B] rotates, causing the Separator [A]to move away from the print drum.

PAPER EJECTION WING MECHANISM

3. Paper Ejection Wing Mechanism

The left- and right-hand ejection wings on the Suction unit can be set manually to the raised [B] or lowered[C] positions to suit the paper ejection requirements. Normally, the ejection wings are raised [B] forregular paper and lowered [C] for cards.

The ejection wings are raised and lowered by moving the Wing position knob [D] located below the left-hand Ejection wing [A] up or down.

The Wing position knob [D] has a protruding tab [E] inside, which engages with the catch [F] on the left-hand Ejection wing [A]. Moving the Wing position knob [D] up and down therefore moves the Ejectionwings up and down.

SEPARATOR MOUNTING POSITION

Adjustment

1. Separator Mounting Position

(1) Using test chart No.15, create a master and make prints. Check that the paper does not jam on thedrum and that there is no black line through the center of the paper caused by the Separator touchingthe print drum. The Separator position is OK if there is no paper jamming on the print drum with 5mm white margin on the top of the prints.

(2) If the paper sticks to the print drum or black line appears on the printed sheet, stop the print drum atposition-A, switch off the power, remove the rear cover, and then remove the following component.

• Separation fan unit

(3) Insert a screwdriver through the insertion point [B] at the bottom left of Pressure lever A [A], andloosen the retaining screw [D] on the Separator positioning plate[C].

(4) Insert a penlight inside the machine, on top of the suction unit, and inspect the tip of the Separator [E]through the square opening in the machine side frame located just above Pressure lever A [A].

(5) Move the Separator positioning plate [C] and tighten the separator positioning plate retaining screw[D] so that the gap between the Separator [E] tip and the Print drum surface [F] is 1.0 mm to 1.5 mm.

Symptoms

• If the tip of the Separator [E] touches the Print drum surface [F], it will scratch the surface of themaster, causing a black line on the printed sheets.

• Conversely, if the gap is too wide, the paper will not be properly released from the print drum, andsticks onto the print drum.

MASTER ON DRUM (IN PRINTING) CHECK MECHANISM

Mechanism

1. Master on Drum (in Printing) Check Mechanism

This mechanism checks whether there is a master on the print drum when printing begins.

The print drum begins to rotate when the START key is pressed, and when the print drum reaches the 75°position, the Master sensor [B] checks whether there is a master [C] on the print drum.

The information checked by the Master sensor [B] is stored until either the print drum is pulled out or thepower is switched off. Subsequent printing therefore starts immediately after the START key is pressed.

If light is not reflected back to the Master sensor [B] (implying that the master is absent) when the printdrum reaches the 75° position at the start of the printing, it is assumed that there is no master on the printdrum.

PRINT DRUM SET MECHANISM

2. Print Drum Set Mechanism

The Print drum set sensor [A] checks whether the print drum is correctly set in the machine.

A light beam from the Print drum set sensor [A] is transmitted when the levers are gripped, and blockedwhen they are released.

The light beam of print drum set sensor [A] is therefore transmitted if the print drum is not correctly set inthe machine.

SQUEEGEE ROLLER ROTATION MECHANISM

4. Squeegee Roller Rotation Mechanism

The main motor drives the Joint gear [A] via the Junction gear ass’y [B], and this rotates the Print drummain gear [C].

The rotation also drives the Squeegee roller gear (R) [D] via the gears to rotate the Squeegee roller [E].

The Squeegee roller [E] drives the Driven shaft [H] via the Squeegee roller gear (F) [F].

The Squeegee roller gear (R) [D] contains a one-way clutch to prevent the Squeegee roller [E] fromrotating when the print drum is manually rotated in the reverse direction.

INKING MECHANISM

5. Inking Mechanism

When the main motor is operating and the print drum is rotating, if the ink bead moves away from the Inksensor [D], the inking motor activates to pump in the ink from the ink cartridge.

The ink pumped is fed via the hose onto the squeegee roller [E] from the holes in the Ink distributor [F].The inking motor is switched off when the ink reaches the Ink sensor [D].

The ink deposited on the squeegee roller [E] is made into ink bead between the Squeegee roller [E] andDoctor roller [A]. The Driven shaft is rotated to build a smooth ink bead.

The ink is transferred onto the print drum from Squeegee roller [E] via a small gap between the Squeegeeroller [E] and Doctor roller [A].

The Overflow sensor [C] checks to prevent ink from overflowing inside the print drum.

Mechanism

1. Clamp Unit Home Positioning Mechanism

When the START key is pressed to create confidential or normal masters, the Clamp open arm [A] andMaster release arm [B] are checked to ensure that they have returned to the home position (with the lightpaths to both Clamp sensors A [F] and B [G] open). If they are not at the home position, the Clamp motor[C] is activated to move the Clamp cam assembly [D] and return the Clamp open arm [A] and Masterrelease arm [B] to the home position until the light paths to both Clamp sensors A [F] and B [G] are open.

CLAMP PLATE MASTER RELEASE MECHANISM

2. Clamp Plate Master Release Mechanism

When the START key is pressed to create confidential or normal masters, the print drum makes one turnand checks for the presence of master on the print drum. Once the presence of a master on the drumhas been checked, the drum returns to position-A, and the clamp plate master release operation starts.

The clamp motor activates and rotates the Clamp cam assembly [A]. This pushes down the Clamp openarm [B] and opens the Clamp plate [C]. The Master release arm [D] is then pushed down, and the Masterrelease bar [E] is raised, releasing the master from the Clamp plate [C].

The clamp motor continues to run, and raises the Clamp open arm [B] and Master release arm [D]. Themotor is switched off once the light path to Clamp sensor B [G] is opened.

MASTER REMOVAL MECHANISM

Mechanism

1. Master Removal Mechanism

Masters on the print drum are removed as follows.

(1) At the start of master removal, the Master sensor [A] checks whether the master to be removed on theprint drum actually exists.

(2) The clamp plate master removal operation is performed with the print drum at position A to releasethe leading edge of the master from the clamp plate.

(3) The Master removal hook [B] then detaches the master from the print drum as the drum is rotated.

(4) The removed master is fed into the Master compression plate [C].

(5) The removed master is then compressed, and disposed of in the Master disposal box [D].

B: Master removal hook

C: Master compression plate

D: Master disposal box

MASTER ON THE DRUM (BEFORE MASTER REMOVAL) CHECK MECHANISM

2. Master on the Drum (before Master Removal) Check Mecha-nism

When creating confidential or normal masters, the print drum moves to position A, and with the print drumat the 75° position, the Master sensor [A] checks whether or not there is a master [B] on the drum. (Thecheck operation is not performed if information that a master is present has already been stored in themachine’s memory.) The drum rotation angle for the check can be adjusted using test mode No. 580.

If the light from the Master sensor [B] is reflected back, (master present), the master removal sensorchecks whether the master is sent to the master disposal box or not during the master removal.

B: Master

REMOVED MASTER VERTICAL TRANSPORT MECHANISM

3. Removed Master Vertical Transport Mechanism

When the clamp unit is operated to release the leading edge of the master from the clamp plate, theMaster removal motor [A] activates, rotating the Vertical transport rollers [B, C, D, E, F]. The main motoralso rotates the print drum at the same time.

The master is fed between the rollers and pushed into the Master compression plate [H].

The master is guided here by the Master removal hook [G] and G belt [J].

The main motor and Master removal motor [A] stop once the print drum has rotated to position-A. (Thetime at which the master removal motor stops can be adjusted using test mode No. 382.)

When the print drum reaches the 70° and 90° positions, the Master removal sensor [I] checks whether themaster is being fed correctly to the master disposal box. (These drum angles can be adjusted using testmodes No. 380 and 381.)

The master removal hook is normally located at a fixed position close to the print drum, but shifts awayfrom the drum when the drum is pulled out.

The print drum rotation speed during master removal can be adjusted using test mode No. 387.

DISPOSED MASTER COMPRESSION MECHANISM

4. Disposed Master Compression Mechanism

1) Initializing

• If the light path on the Master compression sensor [B] is open when the power is switched ON orwhen everything is reset, the master compression motor operates in the compression direction,and when the light path to the master compression sensor is blocked, it operates in reverse untilthe light path is open again.

• If the light path to the Master compression sensor [B] is blocked when the power is switched ON orwhen everything is reset, the master compression motor operates in the return direction until thelight path is open again.

• If the light path to the Master compression sensor [B] is blocked when starting master removal, themaster compression motor operates in the return direction until the light path is open. (The initializ-ing operation is not performed if the light path to the master compression sensor is open whenstarting master removal.)

2) Master compression

Once the removed master vertical transport operation is complete, the master compression motoroperates in the compression direction to lower the Master compression plate [A]. The light path tothe master compression sensor is briefly blocked by the Master compression sensor plate [C].

When the light path to the master compression sensor is subsequently opened again, the mastercompression motor stops (the stop time can be adjusted using test mode No. 384), and thenoperates in the return direction to return the master compression plate to its home position.

3) Ejection of removed master

The master removed by the vertical transport operation is pushed inside the Master compressionplate [A]. Compression is performed by the master removal motor rotating the Master compressionplate [A] on the Pivot shaft [D]. The Piston shaft link [E] also rotates, but it rotates on the Piston shaft[F] rather than on the Pivot shaft [D]. This causes the Piston block [G] to move in the direction inwhich the master ejects out.

B: Master compression sensor

C: Master compression sensor plate

D: Pivot shaft

E: Piston shaft link

F: Piston shaft

G: Piston block

4) Disposed-master-full detection

The removed-master-full detection is performed using the following two mechanisms, and a master-full indication is displayed by either.

(1) The number of masters removed after resetting following the previous master-full indication iscounted, and the master disposal box is determined as full when the count reaches the presetvalue.

* The preset master-full count can be set using test mode No. 386.

The master count is not incremented if a master removal error occurs or if the master to beremoved is not detected on the print drum.

(2) Mechanism for mechanically determining that the master disposal box is full (see below.)

Once the light beam of the master compressionsensor is blocked by the master compression sensorplate, the compression operation stops, and themaster compression plate returns to the homeposition.

Once the master inside the master disposal box hasbeen sufficiently compressed, the mastercompression plate stops rotating, but the mastercompression sensor plate continues to rotate.(The master compression plate is mounted to thepivot shaft via a spring, whereas the mastercompression sensor plate is mounted directly to thepivot shaft.)

When the master compression motor operates to startmaster compression, the master compressionsensor is immediately blocked by the mastercompression sensor plate. As the operationcontinues, the disposal box full sensor is brieflyblocked by the master compression plate, but is thenopened.

At the start of compression, the light paths to themaster compression sensor and disposal box fullsensors are open.

Pivot shaft

Master compression plate

When the master disposal box becomes full, themaster compression plate stops rotating before theremoved-master-full sensor is blocked.

When the light path to the master compressionsensor is open and the removed-master-full sensor isnot blocked, the master-disposal-box-full indication isdisplayed.



DISPOSAL BOX SAFETY SWITCH

5. Disposal Box Safety Switch

The master disposal box safety switch checks whether the master disposal box and master disposalgate housing are properly positioned.

If the master disposal gate housing is locked and correctly set, the bracket on the master disposal gatehousing is positioned close to the safety switch.

When the master disposal box is mounted, the safety switch unit moves back, and the safety switch ispushed against the master disposal gate housing.

The master disposal box full indication is reset if the master disposal box safety switch is released (themaster disposal box removed) for more than 5 seconds. The master disposal box count memory is alsoreset to zero.

ORIGINAL SCANNING MECHANISM

2. Original Scanning Mechanism

The FB read pulse motor [J] drives the front and rear Wire spool pulleys [G] via the 2-stage reductionpulleys linked by the Timing belts [H], [I]. The front and rear wire spool pulleys are configuredsymmetrically.

The wire [S] has one end secured to the frame via Coil spring [A], and is wound onto Sliding pulley No. 2[E] mounted on the Mirror carriage [B]. It is wound approximately 6.5 times around the rear wire spoolpulley [G] via the Fixed pulley [F] secured to the frame. It is then attached to the Lamp carriage [C] andthen secured to the frame via Sliding pulley No. 1 [D] mounted on the Mirror carriage [B]. The Lampcarriage [C] carries two original illumination Lamps [K] (and lamp inverters) and Mirror No. 1 [M], and themirror carriage carries the two mirrors [N], [O].

The mechanism uses a “full/half-rate mirror scanning” system, in which the mirror carriage moves 1/2 Lmm as the lamp carriage moves L mm in the same direction. This means that when the FB read pulsemotor [J] is activated, the original surface can be scanned while maintaining a constant distance betweenthe original and the center of the lens mounted on the frame. The original on the scanner tableilluminated by the lamp is reflected via mirrors No. 1, 2, and 3, and is then focused onto the CCD [R] bythe lens [Q] in the lens ass’y [P].

FLAT BED INITIALIZATION MOVEMENT

3. Flat Bed Initialization Movement

Initialization is performed in the following situations to bring the flat bed unit to standby mode.

• When power is switched on

• When everything has been reset

Initialization operationThe Image scanner ADF shading sensor [A] is checked, and if it is OFF (light path open), the Flat-bedread pulse motor [B] is activated in the return direction until the light path is blocked, and moves the Lampcarriage [C] towards the left in the photograph. Once the image scanner ADF shading sensor is ON(blocked), it is moved a further 3 mm before the operation ends. (This position is the “standby position”.)The actuator plate of the image scanner ADF shading sensor is fixed to the lamp carriage.

No movement is made when the image scanner ADF shading sensor is ON (blocked).

(1) If the image scanner ADF shading sensor does not switch to ON when the flat bed read pulse motoris moved 487 mm in the return direction, the flat bed read pulse motor is assumed to be locked, and“T14-100” is displayed.

STAGE GLASS ORIGINAL DETECTION SYSTEM

4. Stage Glass Original Detection System

The Flat bed original detection sensor [B] checks whether an original is placed on the Stage glass [A].The Flat bed original detection sensor [B] performs its check as soon as the Stage cover [C] is closedhalfway, blocking the light path to the Stage cover sensor [D].

If the light path to the Flat bed original detection sensor [B] is open (original present), the Master-Making/Print indication on the panel switches to “Master-Making”, and the thermal pressure motor is activated tolower the thermal head until the TPH pressure sensor switches ON.

At the same time, the lamp illuminates until the shading compensation is made (automatic base controloperation is also performed if original scanning intensity is set to “Auto”), and the lamp carriage returns tothe scanning start standby position and waits. If START key is not pressed within 60 seconds, the lampturns off and the lamp carriage returns to the standby position.

FLAT BED AUTOMATIC BASE CONTROL

5. Flat Bed Automatic Base Control

This operation is performed after the shading compensation for line mode only when the originalscanning density is set to “Auto”. (It is not performed in photo, line/photo, dot, and book modes.)

When the START key is pressed, the lamp illuminates, and the flat bed read pulse motor activates in thescanning direction. It moves 41 mm after the image scanner ADF shading sensor switches from ON toOFF, and then pauses for a set period. Shading compensation is then performed while it moves 8 mm,and it then moves 15 mm (9 mm from the leading edge of the original) before the image sensor scansthe surface density of the original. After this, the lamp carriage moves approximately 2.6 mm twice andscans the surface density of the original. (Total 3 times)

The flat bed read pulse motor then operates in reverse (in the return direction) to return the lamp carriageto the scanning start standby position, and proceeds to FB scanning operation 1.

FB ORIGINAL SCANNING MECHANISM

6. FB Original Scanning Mechanism

This scanning operation describes the following situations. One is in which the ABC (Auto Base Control)is not performed. The other is when the START key is pressed within 60 seconds of placing the originalon the stage glass (START from FB original scanning operation 1), and when the START key is pressedafter 60 seconds.

If the START key is pressed after 60 seconds have elapsed, the lamp [B] illuminates, and the Flat bedread pulse motor [A] activates in the feed direction. The Lamp carriage [C] moves to the shadingcompensation position, and shading compensation is performed. (See the previous section for the casein which line mode is selected with original scanning density set at “Auto”, i.e. with ABC.)

It then moves a preset distance in the scanning direction (to the right) from the scanning start standbyposition, and the write pulse motor activates. It then moves a further preset distance, switching ON theread/write signal and initiating scan of the original. (The master making process starts at the same time.)

Once the master making for the size of the original is made, the read/write signal is switched OFF, andscanning ends. (The master making process also ends at the same time.) The Flat bed read pulsemotor [A] moves the lamp carriage a further 3 mm in the scanning direction before stopping. The Lamp[B] turns off, and the scanning operation is complete.

The Lamp carriage [C] then returns to the standby position. (Flat bed initialization operation)

ADF ORIGINAL SET MECHANISM

Mechanism

1. ADF Original Set Mechanism

When the original is set along the original guide fence and pushed up against the Original stopper gate[C], the ADF original detection sensor [A] is activated (light path open) and the Master/Print indicator on thepanel switches to “Master”. The thermal pressure motor operates to lower the thermal head until the TPHpressure sensor is activated.

After a preset interval, the ADF read pulse motor [O] reverses to lower the Pickup roller [B] in the directionshown by the arrows and withdraw the Original stopper gate [C] upwards. (The one-way clutchincorporated between the Registration roller gear [N] and registration roller shaft prevents theRegistration roller [G] from rotating here.)

Once the Pickup roller [B] descends to push against the original, the Pickup roller [B] and Original stripperroller [D] rotate in the original transport direction, and a single original is fed forward by the action of theOriginal stripper roller [D] and Original stripper pad [E]. This activates the ADF original registration sensor[F] (light path blocked) and the edge of the original is stopped by the Stationary registration roller [G].Once a preset interval has elapsed from when the ADF original registration sensor [F] was activated, theADF read pulse motor [O] operates in the forward direction. This raises the Pickup roller [B] and at thesame time rotating the Registration roller [G], Original read roller [I], and Original ejection roller (top) [J],which are all linked by the Timing belt [M], in the feed direction.

The original stops briefly after it has been moved 100 mm from the original set position.

ADF ORIGINAL SCANNING MECHANISM (WITH AUTOMATIC BASE CONTROL)

2. ADF Original Scanning Mechanism (with Automatic Base Con-trol)

(This operation only occurs when the original scanning density is set to “Auto”.)

Once the ADF original setting operation is complete, pressing the START key illuminates the lamp.

The Flat bed read pulse motor is activated immediately, moving the Lamp carriage in the feed direction tothe shading position. Shading adjustment is performed before moving back in the return direction andstopping at the ABC scanning position (3 + b) mm in front of the normal ADF scanning position.

The ADF read pulse motor meanwhile operates in the forward direction, rotating the Registration roller,Master lead roller, and Original ejection roller (top) in the feed direction. The original is fed forward 26.9mm and stops after the Original IN sensor activates (light path blocked), and the intensity of the originalbackground color is scanned by the image sensor in this position. The FB read pulse motor then movesthe Lamp carriage back (3 + b) mm in the return direction. (Normal ADF original scanning position)

The ADF read pulse motor immediately operates in the forward direction, and at the same time, the read/write signal activates, causing scanning of the original to start.

The read/write signal is deactivated a preset interval after the Original IN sensor is deactivated (light pathopen) when the original is moved away (or immediately if the Write pulse motor has rotated the equivalentof the paper size as previously specified by the user settings). The ADF read pulse motor then operatesat high speed as soon as scanning is complete.

Once the original is transported a preset distance after the Original OUT sensor deactivates, the ADF readpulse motor stops and the ADF original scanning operation is complete.

The Automatic Base Control function does not operate in Photo, Line/Photo, or Dot modes.

CHAPTER 13. MASTER MAKING SECTION

MASTER MAKING & MASTER LOADING

Mechanism

1. Master making & master loading

The master making & master loading mechanism is made up of the following components.

1) Scanner Table Set Detection Mechanism

The Flat bed set switch [A] confirms that the original is positioned on the scanner table.

The Master loading unit sensor [B] confirms that the master loading unit is set.

The Master end sensor [C] confirms that master roll has ran out of master.

2) Master Cutting Mechanism

The master cutting operation is performed by the Cutter motor [D], and the cutter motor stop positionis confirmed by the Cutter home position switch [E].

3) Thermal Print Head Elevation Mechanism

The Thermal print head (TPH) [F] is raised and lowered by the Thermal pressure motor [G], and theposition is confirmed by the TPH pressure sensor [H].

4) Master Making Section Mechanism

Master making is performed by lowering the Thermal print head [F] and transporting the masterclamped between it and the Write roller [I]. The master is transported by the Write roller, which isdriven by the Write pulse motor [J]. Created masters are stored inside the master stocker [K].

5) Master Loading Mechanism

Masters that have been created are fed to the print drum and clamped, and then loaded by rotatingthe print drum.

The master is transported by the Load roller [M], which is driven by the Load pulse motor [L].

SCANNER TABLE SET DETECTION MECHANISM

2. Scanner Table Set Detection Mechanism

Scanner table and master loading set detection mechanism

The Flat bed set switch [A] confirms that the scanner table is closed.

The Flat bed set switch [A] is the interlocking switch for the main motor, and this forces the Main motor,Clamp motor, and TPH power to an emergency stop if the Scanner table is opened while the system isoperating.

The Master loading unit switch [B] confirms that the Master loading unit is set, and the master settingoperation is performed once the Master loading unit is set.

Master end detection

The end of the master roll is confirmed by the Master end sensor [C] detecting the black end markattached to the end of the master on the master roll.

The Master end sensor [C] checks every 10 ms while the master is being transported, and gives anindication on the panel when the end mark is detected twice in succession.

MASTER CUTTING MECHANISM

3. Master Cutting Mechanism

• The master is cut by the upper cutter of the Cutter unit being moved up and down by the Cutter motor [A].

• The Cutter motor rotates in a constant direction, and the Cutter home position switch [B] confirms theposition of the upper cutter.

• The Cutter is at the home position when it is not pressing against the Cutter home position switch [B],and if the switch is depressed briefly after the Cutter motor starts, the motor stops when the switch is nolonger depressed.

THERMAL PRINT HEAD ELEVATION MECHANISM

4. Thermal Print Head Elevation Mechanism

Thermal print head elevation

When the system is on standby or when winding the master onto the print drum after master making,the Thermal print head is raised from the Write roller. Conversely, for master making and duringtransport, the Thermal print head is lowered and pressed onto the Write roller.

The Thermal print head is raised and lowered by the Pressure release cam [B], which is driven by theThermal pressure motor [A].

The Pressure release cam [B] is an eccentric cam, which raises and lowers the TPH pivot plate [C] asit rotates. The raised and lowered stop positions for the motor are detected by the TPH pressuresensor [E], which is blocked by the Pressure detection disc [D]. The Sliding plate [F] and Blade link [G]are also moved by the vertical action of the thermal head.

Thermal print head raised position

In the Thermal print head raised position, the Load roller No. 1 (top) [H] and Load roller (top) [I] alsorise.

At the same time, the Blade cushion [J] descends, and applies back tension to the master while it isbeing wound onto the print drum to prevent creases in the master.

Thermal print head’s lowered position

In the Thermal print head lowered position, the Load roller No. 1 (top) [H] and Load roller (top) [I] alsodescend to allow the master to be transported. At the same time, the Blade cushion [J] rises.

Initialization

This moves the Thermal print head to the pressure release (raised) position when power is switchedon, or when everything is reset.

Loading guide plate operation

• In the clamp plate master release operation at the start of master ejection, the front edge of theLoading guide plate is raised by the Master release bar to prevent it from obstructing the leadingedge of the freed master on the drum.

• In the clamp plate master clamping operation at the start of master loading, only the front edgesheet of the Loading guide plate is raised by the Clamp plate, so as to prevent it from obstructingthe master loading operation.

• During master loading, the master being loaded is back-tensioned by the sponge fitted to thebottom of the front edge sheet of the Loading guide plate.

MASTER POSITIONING MECHANISM

5. Master Positioning Mechanism

The master positioning operation is performed to bring the master to the Master positioning sensor whenopening or closing the Master loading unit or during master making.

For master roll replacement

(1) • Insert the leading edge of the new master roll to the Master stopper gate [A], and close the masterloading unit.

• Closing the Master loading unit raises the Master stopper gate.

• The Master loading unit switch monitors operations every 10 ms and determines that the Masterloading unit is closed when the light path is blocked twice in succession. The master is thenchecked by the Master detection sensor [B].

(2) • The Thermal print head is lowered by the Thermal pressure motor, and the Write pulse motor andLoad pulse motor operate to transport the master to the Master positioning sensor [C].

(3) • Once the light path to the Master positioning sensor [C] is blocked by the master, the Write pulsemotor alone operates in reverse to return the master 2 mm. The motor then stops and theThermal print head is raised.

For master cutting

Steps (2) to (3) above are performed following master cutting.

MASTER MAKING

6. Master Making

The sequence of operations from master making to master mounting is as described below.

(1) At the start of master making, the Thermalprint head is lowered to clamp the masterbetween it and the Write roller.

(2) The write pulse motor and Load pulsemotor operate to transport the master tothe Master positioning sensor, where itwaits for scanning system preparations tobe completed.

(3) Once master making can be started, theWrite pulse motor operates to transport themaster to the writing start position beforemaster making commences. The mastercreated is then stored in the masterstocker.

(4) Once the master making in step (3) starts,the Load pulse motor operates to transportthe leading edge of the master to theclamp plate, where it is clamped.

(5) Once master making is finished, theThermal print head is raised, and the printdrum rotates as the master is wound ontoit.

13 – 10RN (Version 1.0)


MASTER MAKING

(6) The print drum pauses at the 220°position, where the master is cut.

(8) The master setting operation is performed.

(7) After the print drum has rotated a further15°, the Master positioning sensorconfirms that the master has been cut.Cutting has been performed correctly if thelight path to the sensor is blocked (nomaster).If the light path to the sensor is open, it isdetermined that an error has occurred.In this case, the cutting operation isrepeated, the Master positioning sensorconfirms whether the master has been cutafter the print drum has rotated a further15°. If it is cut, “A03 Cutting error” isdisplayed, and if it is not cut, “T13 Cuttermotor lock” is displayed.

(1) Make a normal and confidential master, and thencheck the length of the master protruding from theClamp magnet plate.If the amount protruding is within 2 mm ±2 mm, it isnormal. If it is outside this range, adjust as shownbelow.

(2) Run test mode No. 283 and adjust.Setting range: -100 to +100 (-10.0 mm to +10.0mm)Setting units: 1 (0.1 mm)Default: 0 (±0 mm)Increasing the settings increases the amount ofprotrusion.

Note:The relative positioning of already-made masters wound onto the print drum will change if theclamp range is adjusted. The master scanning start position must therefore be readjusted, and itmust also be confirmed that the Vertical printing position adjustment is correct.

3) Master making image elongation/shrinkage adjustmentAdjust the Write pulse motor speed for master making.


(1) Run test mode No. 051 Test print (mesh), andproduce an actual print.Printing is correct if the length of three blockshorizontally is the same as that for four blocksvertically. (Check by folding paper and illuminatingfrom behind.) If it is not correct, adjust as shownbelow.

(2) Run test mode No. 287 and adjust.Setting range: -50 to +50 (-5.0% to +5.0%)Setting units: 1 (0.1%)Default: 0 (±0%)Increasing the settings elongates the image.

Note:The vertical printing position must be readjusted afteradjusting the elongation/shrinkage.

MASTER FEEDING ADJUSTMENTS

4) Write start position adjustment

Adjust the write start position (distance from master positioning sensor ON to read/write signalON).

Adjustment for a leading edge margin of 5 mm assuming that the master clamp range has beencorrectly adjusted.


(1) Run test mode No. 050 Test print (check pattern), to confirm that the master clamp range iscorrectly adjusted.

(2) Cover the print drum surface, aligning the leading edge of the paper with the print drum supportmarks on either side as shown in the diagram, and then transfer the ink to the paper by rubbingfrom above.The position is correct if the leading edge margin is 5 mm. If it is not correct, adjust as shownbelow.

(3) Run test mode No. 281 and adjust.Setting range: -30 to + 50 (-3.0 mm to +5.0 mm)Setting units: 1 (0.1 mm)Default: 0 (±0 mm)

Increasing the settings lowers the write start position and increases the size of the paperleading-edge margin, moving the printing area downward.

5) Master making length adjustment

Adjust the master making area (scanning length)

Adjustment for a bottom edge margin of 2 mm assumingthat the master clamp range has been correctly adjusted.


(1) Run test mode No. 050 Test print (Check pattern),remove the master created from the print drum, andmeasure the length.The master is correct if the length is 357 mm. If it isnot correct, adjust as shown below.

(2) Run test mode No. 282 and adjust.Setting range: -100 to +100 (-10.0 mm to +10.0 mm)Setting units: 1 (0.1 mm)Default: 0 (±0 mm)

Increasing the settings increases the length of themaster making area.

PRINT POSITION ADJUSTMENT

5. Print Position Adjustment

(1) Adjust master creation image elongation and shrinkage. (See page 13-20.)

(2) Adjust scanning image elongation and shrinkage. (See page 11-22 for flat bed unit, and page 12-24for ADF unit.)

(3) Adjust the master clamp amount. (See page 13-20.)

(4) Adjust scanning start position. (See page 11-23 for flat bed unit, and page 12-22 for ADF unit.)

(5) Adjust the master making start position. (See 13-21.)

(6) Adjust the vertical print home position.

• If the print position is offset from the original even after performing adjustment steps (1) to (5),measure the offset, and adjust by the offset amount in Test mode No. 680 (Vertical print homeposition).

* The print position adjustment procedures assume that the mechanical sections, such as the main unitdrive section, paper feed section, and print drum, have been correctly adjusted. Check and adjust themechanical sections first.Likewise, set the data for ADF section adjustment only after mechanically adjusting the flat bed unit.

6. Notes on Stay Assembly

The stay assembly on the main unit drive section is positioned using jigs during factory assembly. Do notloosen or remove the stay assembly mounting screws, as the stay cannot be repositioned once removed.
