ExplanationRemove the claw.

Check visually.

Insert the claw.

The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results in supplying the machine with power. 2. In the digital circuits, '1' is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low". (The voltage value, however, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'. In practically all cases, the internal mechanisms of a microprocessor cannot be checked

CDRH ActThe Center for Devices and Radiological Health of the US Food and Drum Administration put into force regulations concerning laser products on August 2, 1976. These regulations apply to laser products manufactured on and after August 1, 1976, and the sale of laser products not certified under the regulations is banned within the Untied States. The label shown here indicates compliance with the CDRH regulations, and its attachment is required on all laser products that are soled in the United States.

Handling of Laser SystemWhen servicing the area around the laser assembly, be sure to turn off the main power. The machine's covers that can reflect laser light are identified by means of a warning label (Figure). If you must detach a cover showing the label, be sure to take extra caution during the work.

Turn power switch ONThe machine is equipped with 2 power switches: main power switch and control panel power switch. The machine goes on when the main power switch is turned on (i.e., other than in low power mode, sleep mode).

Power Supply

1. As a general rule, do not use extension cords. Using an extension cord may result in a fire or electrical shock. If an extension cord must be used, however, use one for local rated voltage and over, untie the cord binding, and insert the power plug completely into the extension cord outlet to ensure a firm connection between the power cord and the extension cord. 2. The socket-outlet shall be installed near the equipment and shall be easily accessible.

Safety of TonerAbout TonerThe machine's toner is a non-toxic material made of plastic, iron, and small amounts of dye.

Notes Before it Works Serving

At servicing, be sure to turn OFF the power source according to the specified steps and disconnect the power plug.

Do not throw toner into fire. It may cause explosion.

Toner on Clothing or Skin If your clothing or skin has come into contact with toner, wipe it off with tissue; then, wash itoff with water.

Do not use warm water, which will cause the toner to jell and fuse permanently with thefibers of the cloth.

Tonner is easy to react with plastic material, avoid contact with plastic.

Notes When Handling the Lithium and Ni-MH Batteries

RISK OF EXPLOSION IF BATTERY IS REPLACED BY AN INCORRECT TYPE. DISPOSE OF USED BATTERIES ACCORDING TO THE INSTRUCTIONS.

The following warnings are given to comply with Safety Principles (EN60950).

Wenn mit dem falschen Typ ausgewechselt, besteht Explosionsgefahr. Gebrauchte Batterien gem der Anleitung beseitigen.

Analog Control Performed by the CISThe flow of analog image processing performed by the contact image sensor (CIS) is as follows: a. The light reflected by the original is collected by the rod lens array. b. The light is received by the CMOS sensor array. c. The CMOS sensor array converts the received light to an electric signal and outputs it. The CMOS sensor array consists of four channels (units). Each channel is provided with an output correction table to output an image signal after performing gain correction for the input brightness signal.

Magnification Change in Horizontal Scan DirectionIn the horizontal scan direction, magnification is changed as follows depending on the selected magnification rate: 1) When magnification is reduced to 50-99% a. In the Book mode Data is processed on the main controller PCB with the original scan speed held at 61.5 mm/sec or 123 mm/sec. b. When the ADF is used The original feed speed is changed within the range of 61.5 mm/sec or 123 mm/sec to 246 mm/sec depending on the selected magnification rate. Data is not processed on the main controller PCB.

Detecting the Size of OriginalsThe original size is identified by the combination of presence and absence of output levels of the reflection type sensors as summarized in the tables below. - Absence of paper: The light reflected from the reflection type sensor changes when the copyboard cover is open/close. - Presence of paper: The light reflected from the reflection type sensor does not change when the copyboard cover is open/close. This machine is provided with the following sensors. Locations of the sensors are shown below. - Vertical scan direction: Reflection type photo sensors (2 locations for AB; 1 location for Inch) - Horizontal scan direction: Reflection type photo sensors (2 locations for AB; 2 locations for Inch)

5) The original cover is closed (at an angle of 5 deg or less) The original size is identified. Original sensor: Turns off. In identifying the original size, the data obtained in the original size identification process 1 is compared with the data obtained in the original size identification process 2 to check whether these two pieces of data are identical. Note that a wrong original size may be identified because the sensor output level does not change in the following cases: - When the original is A3-sized black - When the original is a book (its thickness does not allow the copyboard cover to close fully, making it difficult to detect the sensor level change).F-2-19

[Description of Control] - At job end (Dust detection) The contact image sensor (CIS) checks the light reflected by the ADF platen roller surface at the read position for presence/absence of dust. After completion of a job,dust detection is performed in the positions A, B and C without concern of presence/absence of dust. 1) Dust detection is performed once at position A. 2) CIS moves to the position B and dust detection is performed once. 3) CIS moves to the position C and dust detection is performed once. 4-a) CIS moves to the position where there is no dust, with priority for the detecting position; A>B>C. 4-b) If dust is detected at all points A, B, and C, move back to position A and the original is scanned at position A.

2-15 Shading Correction (Outline)The CMOS sensor outputs are necessary even for the following reasons even when the density of the original is uniform: (1) Variation in sensitivity among CMOS sensor pixels (2) Variation in light intensity of rod lens array The machine performs shading correction to even out the CMOS sensor output. There are two types of shading correction: shading adjustment performed in the Service

CMOS Sensor DriveThe CMOS sensor used in this machine is a 1-line linear image sensor consisting of 7488 photocells. After completion of photoelectric conversion in the lightreceiving block, the signals are output to the AP circuit in the reader relay PCB in parallel for each channel (total four channels) of the CMOS sensor array.

It measures the density of the standard white plate, and compares the measured value with the target value stored in the shading correction circuit to use the difference between the two as the shading correctionoutput L L H H L H L H H H L
