Precautions
1.3 Power Safety Precautions
1.3.1 Power Source
For 110 VAC printers, do not apply more than 140 volts RMS between the supply conductors or between either supply conductor and ground. Use only the specified power cord and connector. For 220 VAC printers, do not apply more than 260 volts RMS between the supply conductors or between either supply conductor and ground. Use only the specified power cord. This manual assumes that the reader is a qualified service technician.
Plug the power cord, with a grounding prong, into a grounded AC outlet only. If necessary, contact a licensed electrician to install a properly grounded outlet. If the product loses its ground connection, contact with conductive parts may cause an electrical shock.
1.3.2 Disconnecting Power
Turning the power off using the On/Off switch does not completely de-engergize the printer. You must also disconnect the printer power cord from the AC outlet. Position the power cord so that it is easily accessible during servicing so that you may power down the printer during an emergency. Disconnect the power plug by pulling the plug, not the cord.
Disconnect the power cord in the following cases:
if the power cord or plug is frayed or otherwise damaged,
if any liquid or foreign material is spilled into the case,
if the printer is exposed to any excess moisture,
if the printer is dropped or damaged,
if you suspect that the product needs servicing or repair,
whenever you clean the product.
Service Manual 1-3
Precautions
1.4 Electrostatic Discharge (ESD) Precautions
Some semiconductor components , and the respective sub-assemblies that contain them, are vulnerable to damage by Electrostatic discharge (ESD). These components include Integrated Circuits (ICs), Large-Scale Integrated circuits (LSIs), field-effect transistors and other semiconductor chip components. The following techniques will reduce the occurrence of component damage caused by static electricity.
Be sure the power is off to the chassis or circuit board, and observe all other safety precautions.
Immediately before handling any semiconductor components assemblies, drain the electrostatic charge from
your body. This can be accomplished by touching an earth ground source or by wearing a wrist strap device connected to an earth ground source. Wearing a wrist strap will also prevent accumulation of additional bodily static charges. Be sure to remove the wrist strap before applying power to the unit under test to avoid potential shock.
After removing a static sensitive assembly from its anti-static bag, place it on a grounded conductive surface. If
the anti-static bag is conductive, you may ground the bag and use it as a conductive surface.
Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage some devices.
Do not remove a replacement component or electrical sub-assembly from its protective package until you are
ready to install it.
Immediately before removing the protective material from the leads of a replacement device, touch the protective
material to the chassis or circuit assembly into which the device will be installed.
Minimize body motions when handling unpackaged replacement devices. Motion such as your clothes brushing
together, or lifting a foot from a carpeted floor can generate enough static electricity to damage an electro­statically sensitive device
Handle IC’s and EPROM’s carefully to avoid bending pins.
Pay attention to the direction of parts when mounting or inserting them on Printed Circuit Boards (PCB’s).
1.5Service Safety Summary
1.5.1 General Guidelines
For qualified service personnel only:
Refer also to the preceding Power Safety Precautions. Avoid servicing alone: Do not perform internal service or adjustment of this product unless another person capable
of rendering first aid or resuscitation is present. Use care when servicing with power: Dangerous voltages may exist at several points in this product. To avoid
personal injury, do not touch exposed connections and components while power is on. Disconnect power before removing the power supply shield or replacing components.
Do not wear jewelry: Remove jewelry prior to servicing. Rings, necklaces and other metallic objects could come into contact with dangerous voltages and currents.
Power source: This product is intended to operate from a power source that will not apply more then 260 volts rms for a 220 volt AC outlet or 140 volts rms for a 110 volt AC outlet between the supply conductors or between either supply conductor and ground. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation.

Summary of Product
1) Imaging Unit
The imaging unit creates the image using an electro-photo process. The imaging unit consists of the following:
An OPC Drum
Waste Toner Assembly
Charge Roller Assembly
2) Transfer Belt (ITB)
ITB stands for Image Transfer Belt. The image developed on the drum is transferred first to the transfer belt. This is called the T1 transfer (Primary Image Transfer).
The printer uses a four pass process to place the image on the transfer belt.
The image is created on the drum and transferred to the transfer belt in the following order: first yellow (Y),
then magenta, then cyan, and finally black.
3) Transfer Roller
Once the transfer of the image from the drum to the belt is complete, the full image is transferred from the belt to the transfer roller. The transfer roller then transfers the image to paper. This is called the T2 transfer (Secondary Image Transfer).
4) Tray 1 or FCT (First Cassette Tray)
Tray 1 stores and feeds paper to the printer. A pick roller picks paper, controls drive, feeds paper, and removes static electricity from the paper.
Tray 1 Specifications:
Paper Feed: side registration
Paper Direction: Long edge
Paper Discharge: Separation Claw
Capacity: 250 Sheets

7) Feeder
Paper Arrangement: Side Registration.
Drive: Main Motor DC
Paper Management: Feed Clutch
8) Duplex Unit
The duplex unit is used to reverse paper feed to print the on backside of paper. The duplex unit is not an option. The transfer roller is part of the duplex unit.
Duplex Unit Specifications
Drive: Main Motor DC
Paper Reversal: After the front side of the original document is printed and begins reaches the exit path, the
exit roller pulls the paper back through the duplex unit for printing on the reverse side.
9) Exit Unit
The exit unit guides the paper to the output tray. Exit Unit Specification
Capacity : 250 sheets standard (20 lb)A4/Letter (There is no output tray full sensor)
Paper Direction: Face Down
Exit Roller Drive: Driven by the main motor DC, rotating clockwise for normal feed and counter-clockwise
to reverse feed for duplex printing.
10) Toner Cartridges
There are four toner cartridges, one each for C (Cyan), M (Magenta), Y (Yellow) , and K (Black).
11) Fuser Unit
The fuser unit consists of 2 heat lamps, 2 heat rollers, 2 thermostats and one thermister. After the image is transferred from the transfer roller onto the media, the fuser melts and fuses the toner to the paper by applying pressure and heat to complete the print job.
12) Laser Unit (LSU)
The laser unit forms the latent image on the surface of the drum using a static charge.
13) Main Motor (Brushless DC)
The main motor drives the following components: imaging unit, transfer belt, feeder, fuser, exit, and duplex unit. Main Motor Specification:
Power: 40W Max (24V)
14) DEVE Drive Motor
The DEVE motor drives the toner cartridges and transfer belt cleaning cam. DEVE Motor Specification:
Power : 40W Max (24V)
4-4
Summary of Product
15) Low Voltage Power Supply (LVPS or SMPS (Switching Mode Power Supply))
The LVPS uses the AC supply voltage to generate the DC voltages used by the printer.
The LVPS has 3 output channels (+3.3V, +5V, +24V).
The LVPS sends AC power to the fuser and DC voltages to the cover interlock switches, and to the main
board.
The LVPS generates power to the, motors, clutches, waste toner motor and the CRUM reader board
(DEVE_OEM board).
AC heater control unit supplying power to the fuser is also located on the LVPS.
16) HVPS (High Voltage Power Supply)
The HVPS creates the high voltages used for the electro photographic process.
The high voltage is created from the 24V line from the LVPS.
High Voltage output is supplied to the charge roller, toner cartridge, imaging unit (T1), transfer belt (T2),
and transfer roller.
17) Main Board
The main board receives DC voltages from the LVPS to control the sensors, fuser fan, imaging components, main motor and HVPS.
The main board has several major function blocks.
CPU Block: Creates bitmap data for the engine to print and controls various devices that are needed to
operate the printer.
Engine Control Block: Manages images and controls motors, clutches, and solenoids.
Memory Block : Stores video data and print orders from the computer.
ROM Block : The printer operating system and PDL interpreter are stored here.
USB 2.0 Block, IEEE 1284 Block, Option Block, and Control Panel.
18) DEVE Drive Board
Each toner cartridge requires high voltage when that color is being processed. The DEVE drive board, using four solenoids, selects which cartridge is to receive the supply voltage. The DEVE board also controls the DEVE motor, DEVE clutch, and DEVE solenoid drives. These are activated in sequence as required by the print process.
19) DEVE_OEM Board (CRUM Reader)
The DEVE_OEM board verifies the toner cartridges are new, used and whether they are Xerox parts. An error message will display on the front panel if the toner cartridge is a non-Xerox toner cartridge.
20) Waste Toner Assembly
A cleaning blade removes waste toner from the drum after every image is transferred to the transfer belt. Once the complete image is transferred from the transfer belt to paper, the transfer belt cleaning solenoid activates and another cleaning blade removes waste toner from the transfer belt. All the waste toner is then transferred to the waste toner cartridge.
Replace the Waste Toner Cartridge immediately if the error message “Waste Toner Cartridge Full/ Not Installed” is displayed on the control panel.
Caution
Failure to have a waste cartridge installed or replaced when full can damage the printer.

1. Transfer Belt (T1) Receives the four color image from the drum in Y, M, C, K order.
2. Image Transfer Cleaner After the final image is transferred onto paper by the transfer roller, any
toner left on the belt is removed using this cleaning blade.
3. PTL Pre-Transfer Lamp The pre-transfer lamp removes the charge holding the toner on the drum
allowing the toner to be transferred to the belt.
4. CTD Sensor This sensor monitors the density of each color toner being placed on the
drum. It is also used to detect a toner cartridge empty state.
The drum surface and toner have different light reflecting characteristics, the CTD sensor uses this to detect the difference in the amount of toner present on the drum.
Caution
Be careful not to contaminate the surface of the CTD sensor, this will cause problems with color reproduction and quality.
Process: The TRC (Tone Reproduction Curve) control process is used at power on, after waking from sleep mode, after every 100 pages of printing, and after installing a new toner cartridge or OPC drum to check the toner density transferred onto the OPC. Small patches of 6.25%, 25%, 37.5%, 50%, 62.5%, 75%, 87.5%, and 100% density for each of the 4 colors are deposited on the OPC drum surface and the CTD is used to detect how much toner is transferred. Based on an internal calibration curve the TCR control process adjusts the developer bias voltage to ensure that optimal toner transfer takes place.

5. Transfer Roller (T2) The transfer roller transfer the final toner image from the transfer belt to
the paper.
The HVPS applies the image transfer bias voltage to the transfer
roller allowing transfer of the image from the belt onto the paper.
When the image is to be transferred from the transfer belt to the
paper, the transfer roller pressure contact solenoid is activated and this activates a cam which moves the transfer roller into contact with the belt.
After the transfer has taken place, any remaining charge on the paper
is removed by applying a charge removal bias (generated in the HVPS) to a detack saw.
Transfer method: Semi-conductive roller contact method
Effective transferring range: 218 mm (i.e. maximum image length)

Heat Roller
1) Thermostat (2)
The thermostats are temperature cut-off devices.If the heat lamps or heat rollers overheat, the thermostat turns off power to the lamps to prevent fire.
2) Thermistor (1)
The thermistor detects the temperature of the heat roller’s surface, and feeds this information to the main processor. The processor uses this information to control power to the fuser lamps in order to maintain a steady temperature to the heat rollers.
3) Heat Roller (2)
Halogen lamps are used to heat the heat rollers. The heat rollers have a special Teflon surface which ensures that any melted toner coming into contact with the heat roller surface does not stick. Paper passes between the two rollers which evenly heat the paper from both sides to melt the toner and fusing it onto the media.
4) Safety Information - Warning
Overheat protection 1st level protection: Print engine is stopped if overheat
is condition is detected. 2nd level protection: Software turns off lamp power if
overheat condition is detected.
3rd level protection: Thermostat turns off lamp power if overheat condition is detected. Protection device
Fuser power is turned off when the duplex cover or the toner cartridge door is open. The printer keeps the surface temperature of the fuser cover under 80° C, and has a caution label attached inside
the exit cover where it can be easily seen by the user.
Service Manual 5-7
System Outline
5.1.6 Exit
After passing through the fuser, media is ejected into the output tray. Any static electrical charge is removed by static discharge brushes.
When operating in duplex print mode, after printing the front side of the page, the paper exit roller reverses to feed the paper back into the printer in order to print on the back side of the paper.
5.1.7 Waste Toner Collection Process
Waste toner left on the drum and on the transfer belt is collected into the waste toner cartridge.
After transferring the toner image from the drum to the transfer belt, a cleaning blade removes waste toner
off the drum depositing it into the waste toner cartridge.
A second transfer belt cleaning blade removes waste toner from the transfer belt and deposits waste toner
into the waste toner cartridge.
1) Waste toner cartridge sensor
The waste toner cartridge sensor is used to detect the presence of the waste toner cartridge and its full condition.
> No waste toner cartridge
If a waste toner cartridge is not installed in the printer, the waste toner sensor actuator blocks light from the sensor LED and displays a cartridge not installed message on the control panel.
> Low waste toner
If the sensors LED light reaches the photo sensor, by passing through the waste cartridge, this indicates the waste toner cartridge has not reached its full state.
> Waste toner tank full
If the sensors LED light is blocked or not received by the photo sensor, it will indicate a waste toner cartridge full state on the control panel.
