Handling Precautions The following instructions are for your own personal safety, to avoid injury and so as not to dam-age the machine 1. Ensure the machine is installed on a level surface, capable of supporting its weight. Failure to

do so could cause the machine to tip or fall. 2. The machine contains many rollers, gears and fans. Take great care to ensure that you do

not catch your fingers, hair or clothing in any of these rotating devices. 3. Do not place any small metal objects, containers of water, chemicals or other liquids close to

the machine which if spilled could get into the machine and cause damage or a shock or fire hazard.

4. Do not install the machine in areas with high dust or moisture levels, beside on open window or close to a humidifier or heater. Damage could be caused to the machine in such areas.

5. Do not place candles, burning cigarettes, etc. on the machine, these could cause a fire.

Assembly / Disassembly Precautions Replace parts carefully, always use Xerox parts. Take care to note the exact location of parts and also cable routing before dismantling any part of the machine. Ensure all parts and cables are re-placed correctly. Please carry out the following procedures before dismantling the machine or replacing any parts. 1. Check the contents of the machine memory and make a note of any user settings. These will

be erased if the mainboard is replaced. 2. Ensure that power is disconnected before servicing or replacing any electrical parts. 3. Disconnect printer interface cables and power cables.4. Be sure to remove the print cartridge before you disassemble any parts. 5. Only use approved spare parts. Ensure that part number, product name, any voltage, current

or temperature rating are correct. 6. When removing or re-fitting any parts do not use excessive force, especially when fitting

screws into plastic. 7. Take care not to drop any small parts into the machine. 8. Handling of the OPC Drum

- The OPC Drum can be irreparably damaged if exposed to light. Take care not to expose the OPC Drum either to direct sunlight or to fluorescent or incandes-cent room lighting. Exposure for as little as 5 minutes can damage the surface’s photocon-ductive properties and will result in print quality degradation. Take extra care when servicing the machine. Remove the OPC Drum and store it in a black bag or a lightproof container. Take care when refitting covers as light is can be admitted through the OPC area and can damage the OPC Drum. - Take care not to scratch the green surface of the OPC Drum Unit. If the green surface of the Drum Cartridge is scratched or touched, the print quality will be compromised.

9. Remove dust and foreign matter.

ESD Precautions Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly called “Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs are: integrated circuits, some field effect transistors, and semiconductor “chip” components. The techniques outlined below should be followed to help reduce the incidence of component damage caused by static electricity.

CAUTIONBe sure no power is applied to the chassis or circuit, and observe all other safety precautions. 1. Immediately before handling a semiconductor component or semiconductor-equipped

assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially available wrist strap device, which should be removed for your personal safety reasons prior to applying power to the unit under test.

2. After removing an electrical assembly equipped with ESDs, place the assembly on a conduc-tive surface, such as aluminium or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity of the assembly.

3. Use only a grounded tip soldering iron to solder or desolder ESDs. 4. Use only an “anti-static” solder removal device. Some solder removal devices not classified

as “anti-static” can generate electrical charges sufficient to damage ESDs. 5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges

sufficient to damage ESDs. 6. Do not remove a replacement ESD from its protective packaging until immediately before

installing it. Most replacement ESDs are packaged with all leads shorted together by conduc-tive foam, aluminium foil, or a comparable conductive material.

7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed.

8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed, until completely plugged or soldered into the circuit.

9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the brushing together of clothing fabric and lifting one’s foot from a carpeted floor, can generate static electricity sufficient to damage an ESD.

PHASER 3428 09/06 VERSION 2 ix

Toner Cartridge Service Only toner cartridges supplied by Xerox should be used. Printing defects or set damage caused by the use of non-approved print cartridges or un-licensed toner refills are not covered by the guar-antee.

Precautions on Safe-keeping of Toner Cartridge Excessive exposure to direct light for more than a few minutes may cause damage to the car-tridge.

Service Life of Toner Cartridge If the printed image is light due to the toner supply becoming low you can temporarily improve the print quality by redistributing the toner (shake the print cartridge), however you should replace the print cartridge to solve the problem permanently.

Redistributing Toner When the print cartridge is near the end of its life, white streaks or light print occurs. The LCD dis-plays the warning message, “Toner Low.” You can temporarily re-establish the print quality by re-distributing the remaining toner in the cartridge. Note: Help the environment by recycling your used toner cartridge. Refer to the recycling brochure packed with the toner cartridge for details.1. Open the Front Cover.2. Lightly pushing the used cartridge down, pull it out.3. Unpack the new toner cartridge and gently shake it horizontally four or five times to distribute

the toner evenly inside the cartridge.4. Save the box and the cover for shipping. Slide the new toner cartridge in until it locks into

place.

Standard of guarantee for consumable parts. Please refer to User Manual or Instructions on Fax/Printer Consumables SVC manual for the cri-teria for judging the quality of consumable parts the standard of guarantee on those parts.

How to identify a refilled toner cartridge. One way security screws are used in the manufacture of the cartridge – check if these are dam-aged.

FuserThe fuser consists of a Halogen Lamp, Heat Roller, Pressure Roller, Thermistor and Thermostat. It fuses toner to paper with pressure and heat to complete the printing job.

• Heat Roller The surface of the Heat Roller is heated by the Heat Lamp. As paper passes between the Heat roller and Pressure roller, toner is melted and fused permanently onto the paper. The surface of the roller is coated with Teflon. This ensures that toner does not adhere to the roller surface. • Pressure roller The Pressure Roller is mounted under the heat roller and is electrically conductive. The pressure roller is made of a silicon resin, and the surface of the roller is coated with Teflon. This ensures that toner does not adhere to the roller surface. • Temperature Control Device (Thermostat) The thermostat is a temperature sensing device, which cuts off the power to the heat lamp to pre-vent damage to the printer if the heat roller overheats. • Temperature Sensor (Thermistor)



The thermistor detects the surface temperature of the heat roller. This is needed to regulate the temperature of the printer.

Safety Features • To prevent overheating

1st protection device: Hardware stops when printer is overheated 2nd protection device: Software system stops when printer is overheated 3rd protection device: Thermostat cuts off power to the lamp.

• Safety device Fuser power is cut off when the front cover is opened LSU power is cut off when the front cover is opened The temperature of the fuser cover's surface is maintained at less than 80ºC to protect the user and a caution label is attached where the customer can see it easily when the rear cover assembly is opened.

LSU (Laser Scanning Unit) The LSU unit is controlled by a video controller. It scans video data received from video controller with a laser beam by using the rotation principle of the polygon mirror to create the latent image on the OPC drum. It is the core part of LBP. The OPC drum rotates at the same speed as the paper feeding speed. It creates a HSYNC signal and sends it to the engine when the laser beam of the LSU reaches the end of the polygon mirror. The engine detects the HSYNC signal and then arranges the vertical line of the image on paper. After detecting the HSYNC signal, the image data is sent to the LSU to arrange the margin on the paper. Each side of the polygon mirror represents one line of scanned data.

Sensors

Paper Empty Sensor The Paper empty sensor on the HVPS detects whether the cassette tray is stocked or empty.

MP SensorThe Paper empty sensor on the HVPS detects whether the MP tray is stocked or empty.

Paper Feed SensorWhen paper passes the feed sensor actuator, it emits a signal notifying the paper feeding state to the CPU. Within 1 sec, if the feed sensor does not detect paper after being fed, paper Jam0 occurs.

Paper Exit Sensing The paper exit sensor detects whether paper has exited the printer.

Cover Open Sensing The Cover open sensor is located on the HVPS. When the front cover is opened, the +24V supply, is cut off.

Toner Cartridge Sensing The CRUM detects the presence of a developer. If the developer is mounted, the sub-CRUM can read the information from the toner cartridge by contact with the CRUM involved in the toner car-tridge. If the information of the toner cartridge is invalid, the LCD will display an error message.

SMPS and HVPSThe SMPS supplies DC Power throughout the printer. It receives 110V/220V and converts it to +5VDC and +24VDC to supply power to components. The HVPS board receives +24V and gen-erates high voltage for the THV/MHV/Supply/Dev and supplies it to the developer, toner cartridge and transfer roller.

Fuser AC Control Power The fuser is supplied with AC power which controls a Triac, a semiconductor switch. The AC pow-er will activate the Triac whenever it receives the specified signals from the engine. When the HEATER ON signal is emitted from the engine, the Photo Triac (PC501 LED) then receives and flashes the voltage. The Triac receives the flashed voltage. The AC current then flows in the coil, and heat is occurs.

Engine F/W Process Description

Feeding The drive of the pickup roller in the cassette tray is controlled by a solenoid. The switching of the solenoid is controlled by the general output port or the external output port.

Transfer The charge voltage, developer voltage and the transfer voltage are controlled by a PWM (Pulse Width Modulation). Each output voltage is varies due to PWM duty. The transfer voltage emitted when paper passes the transfer roller is determined by environment recognition. The resistance value of the transfer roller changes due to the surrounding environment of the set. The voltage value which also varies due to the environment, is changed through an AD converter.

Table 10:

1 Stand-by Less than 150W2 Printing Less than 520W3 Sleep-mode Less than 11W



Fusing The temperature change of the heat roller’s surface varies with the resistance value through the thermistor. The resistance value determines how much voltage will be converted into heat to raise the temperature of the fuser. If the value measured by the thermistor is out of controlling range, one of the errors below may occur:

• Open Heat Error This error occurs when a specified temperature is not reached during the warm up process. When this happens, the engine stops all functions and processes. The engine then informs the error sta-tus to the main system. An error message is then displayed on the LCD or LED which informs the user.Recovery is performed automatically. Maximum heat is supplied to the fuser and a second reading is taken. When the specified temperature is reached, the printer resumes operation as normal.

• Low Heat Error This error occurs when the temperature is lower than the specified temperature during stand-by, printing or warm-up mode. When this happens, the engine stops all functions and processes. The engine then informs the error status to the main system. An error message is then displayed on the LCD or LED which informs the user.Recovery is performed automatically. Maximum heat is supplied to the fuser and a second reading is taken. When the specified temperature is reached, the printer resumes operation as normal.

• Over Heat Error This error occurs whenever the printer temperature is higher than specified. When this happens, the engine stops all functions and processes. The engine then informs the error status to the main system. An error message is then displayed on the LCD or LED which informs the user.Recovery is performed automatically. The heat supply is cut off to the fuser and a second reading is taken. When the temperature is a degree below the specified temperature, printer resumes op-eration as normal.

LSU LSU receives the image data from PVC or HPVC and makes a latent image on the OPC surface.It uses the dual beam, LD1 and LD2. But the control method of them is the same.Compared to the single beam, the dual beam has the half of a single beam LSU frequency. Errors related to LSU are as follows:.

• By LReady: When the printing starts, the engine drives the polygon motor of the LSU. If the motor is not in a ready status after a specified time has elapsed, the engine flags the error. After the error is flagged, the engine stops all functions and keeps the error state. The engine then reports the error status to the main system. The error message is then displayed on the LCD notifying the user.

• By Hsync: When the polygon motor is ready, the LSU sends out a signal called Hsync which is used to synchronize each image line. If the engine does not detect consecutive signals for a fixed time, the engine flags a Hsync error. If this happens, the engine stops all functions and keeps the error state. The engine then reports the error status to the main system. The error message is then displayed on the LCD notifying the user.

• LSU Error Recovery: If the LReady or Hsync error happens, the paper exits out beforehand. The engine mode is changed to recovery mode and the engine informs the main system of the engine mode. And the engine checks the LSU error. If the error does not occur, the printing job will be proceeding.

S/W Descriptions

Overview The software of the Phaser 3428 system is constructed with:1. Host software - the application software which operates in Windows and Web Environments.2. Firmware - An embedded software which controls the printing job.

Architecture

Figure 4 Architecture Diagram• Host Software 1. Driver - Translates received documents to a printing command language. The data is then

transfered onto the spooler.2. Stand-alone applications - DMS(Document Management System), RCP(Remote Control

Panel), Printer Status Monitor, Network Management in Window system, 3. Web-based-Application - Offers the same functions as stand-alone applications and

RDC(Remote Diagnosis Control) in Web environment.

• Firmware1. Application (Emulation) - Translates data received from the Host to a printing command lan-

guage (PCL, PS, GDI, etc.).2. Kernel - Controls and manages the whole procedure including control flow and printing jobs

before processing the data to the printer engine.



Data and Control Flow

Figure 5 Data and Control Flow

Printing interfaces (1) Parallel or USB Port During the start of the printing process, the document is converted into PCL string or compressed GDI bit-map data. The printer driver translates all the graphic data and sends it to the host spooler. The spooler then directs the data stream to the printer via a parallel or USB port. The printer kernel receives this data and selects a suitable emulation to process it. When emulation has ended, the kernel sends the output data to the printer engine using a printer video controller (LSU clock) which then continues to the developing process. (2) Network Interface Card During the start of the printing process, the document is converted into PCL string or compressed GDI bit-map data. The printer driver translates all the graphic data and sends it to the host spooler. The network port monitor receives data from the spooler and directs a data stream from the Net-work Interface Card to the printer kernel. The printer kernel receives this data and selects a suit-able emulation to process it. When emulation has ended, the kernel sends the output data to the printer engine using a printer video controller (LSU clock) which then continues to the developing process.
