The following rules apply throughout this Service Manual:

1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with reference to the timing of operation.

In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol, the arrow indicates the direction of the electric signal.

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 in the field. Therefore, the operations of the microprocessors used in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of the DC controller PCB to the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be communicated in the form of Service Information bulletins.All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and be able to identify and isolate faults in the machine.

Latent image formation blockDuring the two steps that comprise this block, an invisible latent image is formed on the photosensitivedrum.

Step 1: Primary chargingTo prepare for latent image formation, the surface of the photosensitive drum is charged with a uniform negative potential. The primary charging bias is applied to the primary charging roller and the roller charges the drum directly.

Primary charging biasPhotosensitive drum

Primary charging roller

Step 2: Laser-beam exposureThe laser beam scans the photosensitive drum to neutralize the negative charge on portions of the drum surface. An electrostatic latent image forms where the negative charge was neutralized.

Developing blockToner adheres to the electrostatic latent image on the photosensitive drum, which becomes visible.

Step 3: DevelopingToner acquires a negative charge from the friction that occurs when the developing roller rotates against the developing blade. The negatively charged toner is attracted to the latent image on the photosensitive drum surface because the drum surface has a higher potential. The developing bias is applied to the developing roller.

Fixing System

OutlineThe fixing/delivery unit fixes the toner onto a print paper and delivers it to the delivery tray.The operation of the fixing/delivery unit is explained in the following.1) The print paper fed from the pick-up/feed unit is fused the toner by the fixing film and the

pressure roller.

2) The print paper delivered from the fixing unit is delivered to the face-down delivery tray or the face-up delivery slot. When the engine controller detects that the heater temperature reaches 50 deg C after the last rotation is completed, it drives the main motor for 50 msec. and dislocates the nip part. This prevents the toner adhering to the pressure roller.

The fixing unit of this printer utilizes the on-demand fixing method. It is structured as shown below.

- Heater:This fixing unit incorporates one heater.Fixing heater (H1): To heat the fixing film (ceramic heater)

- Thermistor:This fixing unit incorporates one thermistor.Thermistor (TH1): Sit almost at the center of the fixing film. (contact type)To control the temperature of the fixing film

- Thermal switch:Thermoswitch (TP1): Sit almost at the center of the fixing film (contact type)If the temperature of the heater rises abnormally high, the contact gets broken andcuts off the AC voltage supply to the fixing heater to interrupt the power supply to theheater.

The temperature control of the fixing unit incorporated as above is operated by the fixing temperature control circuit according to the command from the CPU (IC201) on the DC controller.The followings describe the each circuit and function of the temperature control of the fixing unit.

Internal Residual JamWhen a paper is detected by the TOP Sensor (PS912), Fixing Delivery Sensor (PS916), Paper Width Sensor (PS922), or Duplex Reverse Sensor (PS917) at the time of starting initial rotation, it is judged as an internal residual jam.

Door Open JamWhen a door-open is detected while feeding papers, it is judged as a door open jam.

Protective functionThe low-voltage power supply has a protective function against overcurrent and overvoltage to prevent failures in the power supply circuit. If there flows an overcurrent or an overvoltage, the system automatically cuts off the output voltage.If the DC power is not being supplied from the low-voltage power supply, the protective function maybe running. In such case, turn off the power switch and unplug the power cord. Do not plug in the power cord or turn the power switch on again until the root cause is found.In addition, two fuses in the low-voltage power supply protect against overcurrent. If overcurrent lows into the AC line, the fuse blows and cuts off the power distribution.

SafetyFor user and service technician's safety, the printer has a function to interrupt 24V power supply to the fixing unit and the high-voltage power supply unit.The door switch is turned off and 24V stops under the following condition:

If the cartridge door is opened (SW301 is turned off)The printer has the power switch on the DC line so the AC power flows even the power switch is turned off. Be sure to unplug the power cord before disassembling the printer.

Low-voltage power supply unit failure detectionThe DC controller determines a low-voltage power supply unit failure, stops +24V1 output and notifies E808 to the Main controller when it encounters the following condition:

+24V is higher than a specified voltage

PrefaceOutline

This chapter describes disassembly and reassembly procedures of the printer.The service technician is to identify the cause of printer failures according to the "Chapter 5 TROUBLESHOOTING"on Page 3-1-1 and to follow the disassembly procedures of each part to replace the defective parts or the consumable parts.

Note the following precautions when working on the printer.

1. CAUTION: Before disassembling or reassembling the printer, be sure to disconnect its power cord from the electrical outlet

2. During disassembly, reassembly or transportation of the printer, remove the cartridge if required.

When the cartridge is out of the printer, put it in a protective bag even in a short period of time to prevent the adverse effect of light.

3. Reassembling procedures are followed by the reverse of disassembly unless otherwise specified.

4. Note the length, diameters, and locations of screws as you remove them. When reassembling the printer, be sure to use them in their original locations.

5. Do not run the printer with any parts removed as a general rule.6. Ground yourself by touching the metal part of the printer before handling the PCB to

reduce the possibility of damage caused by static electricity.7. When you replace the part that the rating plate or the product code label is attached, be

sure to remove the rating plate or the product code label and put it to the new part.
