Symbols Used
This documentation uses the following symbols to indicate special information:
Symbol Description
Indicates an item of a non-specific nature, possibly classified as Note, Caution, or Warning.
Indicates an item requiring care to avoid electric shocks.
Indicates an item requiring care to avoid combustion (fire).
Indicates an item prohibiting disassembly to avoid electric shocks or problems.
Introduction
Memo
REF.
Indicates an item requiring disconnection of the power plug from the electric outlet.
Indicates an item intended to provide notes assisting the understanding of the topic in question.
Indicates an item of reference assisting the understanding of the topic in question.
Provides a description of a service mode.
Provides a description of the nature of an error indication.
Introduction
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."

1.4 Safety
1.4.1 Safety of Laser Light
Laser radiation could be hazardous to the human body. For this reason, laser radiation emitted inside this machine is
hermetically sealed within the protective housing and external cover. No radiation can leaak from the machine in the
normal operation of the product by the user.
1.4.2 Handling the Laser Unit
The laser scanner unit emits invisible laser light inside it. If exposed to laser light, the human eye can irreparably be
damaged. Never attempt to disassemble the laser scanner unit. (It is not designed for servicing in the field).
The covers around the laser scanner unit are identified by the following label [1].

1.4.3 Safety of Toner
The machine's toner is a non-toxic material composed of plastic, iron, and small amounts of dye.
Do not put the toner into fire. It may explode.
Toner on the Skin or Clothes
1. If your skin or clothes came into contact with toner, wash with water at once.
2. Do not use warm or hot water, which will cause the toner to jell, permanently fusing it with the fibers of the clothes.
3. Do not bring toner into contact with vinyl material. They are likely to react with each other.

Reading from the ADF
To avoid skew feeding, documents loaded on the document tray are retained in the horizontal direction by the slide
guide. Then, the documents are fed to the separation roller by the pickup roller, and separated one sheet each using
differences in the coefficient of friction among the separation roller, documents, and separation guide.
After that, the feeder roller feeds the document onto the reading glass, and the CCD unit reads out image data of the
document; then, the delivery roller delivers it to the output tray.
The document feed motor drives the various rollers of the ADF.
Reading from the platen glass
The CCD unit driven by the flatbed motor reads out image data of a document on the platen glass.

The machine's laser scanner assembly consists of the laser driver and the scanner motor, which are driven by signals
coming from the engine controller.
The laser driver serves to turn on the laser diode according to the laser control signal and video signals from the
engine controller.
The laser beam moves thorough the collimator less and the cylindrical lens to reach the 4-facet mirror rotating at a
specific speed.
The leaser beam reflected by the 4-facet mirror moves through the imaging lens arranged in front of the 4-facet mirror

Chapter 2
and the reflecting mirror to reach and focus on the photosensitive drum.
When the 4-facet mirror rotates at a specific speed, the laser beam scans the photosensitive drum in keeping with the
mirror rotation, thus drawing static images on the photosensitive drum.
Memo:
BD Fault
The machine identifies a BD fault if it does not detect the /BDI signal within 0.1 sec after the scanner motor is
forced to accelerate. It also detects a BD fault if it does not detect a specific interval of /BDI signals for 2 sec
continuously after the scanner motor has reached a specific revolution (number of rotations).
Scanner Fault
If the machine does not detect the /BDI signal 1.4 sc after it has stopped forcing the scanner motor to accelerate,
it extends the period of detection by 120 sec; if it still does not detect a specific interval of /BDI signals, it
identifies a scanner fault.
BD Error
The machine identifies a BD error if it does not detect the /BDI signal at a specific interval while the /BDI signal
is being generated. It, however, does not identify a BD error under the following condition:
-the door is identified as being open within 0.2 sec after detection of a BD error.
-a BD fault or a scanner fault is detected after a BD error has been identified.
The laser/scanner unit contains parts that cannot be adjusted in the field. Do not attempt to disassemble the laser/
scanner unit.

[3] Blade [7] Primary charging roller
[4] Developing cylinder [8] Cleaning blade
In response to a print command, the engine controller turns on the main motor to drive the photosensitive drum,
developing cylinder, primary charging roller, and transfer charging roller.
Thereafter, the machine uses the primary charging roller to charge the surface of the photosensitive drum to an even,
negative potential and, at the same time, directs the laser beam across the surface of the photosensitive drum. (The
laser beam is modulated to according to the incoming video signals.)
The image thus formed on the photosensitive drum is a static, latent image; it is turned into a visible image by means
of the toner from the developing cylinder. The resulting toner image is then transferred to paper by the work of the
transfer charging roller, and the paper is sent to the fixing assembly. The surface of the photosensitive drum is
cleaned by the cleaning blade so that it is free of residual toner; after cleaning, the primary charging roller once again
charges the surface to an even, negative potential to prepare for the formation of a new static, latent image.
