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."

[8] Cylindrical lens
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 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.

[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.
Drum Cover Shutter
If the surface of the photosensitive drum is exposed to strong light, it develops what is know as "photo memory," which can cause white spots or black lines
in images. To protect the drum against light, the machine is equipped with a drum cover shutter. The drum cover shutter must never be opened unless doing
so proves to be absolutely necessary.

Pickup and Feed Operation (from the cassette)
If the cassette paper sensor detects the presence of paper while the absence of paper is identified in the manual feed pickup assembly, the machine picks up paper
from the cassette.
When the main motor operates and the cassette pickup solenoid goes on, the cassette pickup roller makes a single rotation to pick up paper. The paper is then moved
from the transfer assembly to the fixing assembly by the feed roller; it is ultimately delivered outside the machine by the work of the delivery roller.
When the face-up cover is open, the paper is delivered face-up at the rear of the machine. If the face-up cover is closed, on the other hand, the paper is moved along
the feed guide of the cover, and is delivered face-down at the top of the machine by the work of the face-down delivery roller.
Pickup and Feed Operation (from the manual feed section)
When paper is inserted into the pickup assembly, the manual feed paper sensor detects the presence of paper, and the machine uses the feed roller to pick and hold
the leading edge of the paper. When printing starts, the machine turns on the manual feed pickup solenoid to stop the rotation of the feed roller so that the paper
will not move forward until the laser/scanner and the fixing unit become ready for operation. When the laser/scanner and the fixing unit become ready for operation,
the machine turns off the manual feed pickup solenoid to rotate the feed roller, thus moving the paper forward; the operation thereafter is identical to the operation
used for pickup from the cassette.
2.4.2 Other Control
2.4.2.1 Manual Pickup Control
0012-1874
Upon detection of manually inserted paper, the machine drives the main motor for the specified time to feed the paper to the position where it is to be fed between
the feed rollers. In addition, the machine turns on the feed roller (manual pickup) solenoid to stop rotating the feed rollers, thus preventing the manually inserted
paper from being fed askew. With the paper pressed against the feed rollers, the machine drives the main motor and turns off the solenoid to feed the paper between
the feed rollers.
2.4.2.2 Cassette Pickup Control
0012-1876
With the main motor running, the machine turns on the paper pickup solenoid at the specified timing to rotate the pickup rollers. If paper exists over the top sensor
at the start of timing retry, the machine stops cassette pickup control. If paper does not exist, the machine retries cassette pickup control.

2.4.3 Detection Jams
2.4.3.1 Jam Detection Outline
2.4.3.1.1 Type so Jams
0012-0906
The machine identifies the following types of jams:
Pickup Delay Jam
The top sensor does not go on within a specific period of time after pickup starts.
Pickup Stationary Jam
The top sensor goes on, but does not go off within a specific period of time.
Delivery Delay Jam
The top sensor goes on, but the delivery sensor does not go on within a specific period of time.
Wrap Jam
The delivery sensor goes on, but it goes off before a specific period of time passes.
Delivery Stationary Jam
The delivery sensor goes on, but it does not go off within a specific period of time.
Initial Jam
The top sensor or the delivery sensor goes on while the main motor is starting to rotate.
Cover Open Jam
The machine identifies a condition in which the front cover is opened while it is moving paper.
2.4.3.2 Delay Jams
2.4.3.2.1 Pickup Delay Jam
0012-0907
If the top sensor does not detect the leading edge of paper within 1.2 sec after the start of pickup operation, the machine initiates pickup operation once gain. The
machine identifies a pickup delay jam if the top sensor does not detect the leading edge of paper within 1.2 sec after the 2nd pickup operation.
2.4.3.2.2 Delivery Delay Jam
0012-0908
The machine identifies a delay jam if the delivery sensor does not detect the leading edge of paper within 1.615 sec after the top sensor has detected the leading
edge of paper.
2.4.3.3 Stationary Jams
2.4.3.3.1 Pickup Stationary Jam
0012-0909
The machine identifies a pickup stationary jam if the top sensor does not detect the absence of paper within 3.575 sec after the top sensor has detected the leading
edge of paper.
2.4.3.3.2 Delivery Stationary Jam
0012-0911
The machine moves to a delivery stationary jam sequence if it does not detect a wrap jam.
The machine identifies a delivery stationary jam if the delivery sensor does not detect the trailing edge of paper for 1.715 sec after the top sensor has detected the
trailing edge of paper.
2.4.3.4 Other Jams
2.4.3.4.1 Wrap Jam
0012-0912
The machine starts a wrap jam detection sequence in 0.1 sec if it does not detect a delivery delay jam.
It identifies a wrap jam if the delivery sensor detects the trailing edge of paper within 1.06 sec after the top sensor has detected the trailing edge of paper.
The term "wrap jam" refers to paper that wraps around the fixing pressure roller; its leading edge passes through the delivery sensor, but it jams thereafter. The
machine is designed to identify such a jam so as to prevent wrapping paper from fully moving into the fixing assembly.
2.4.3.4.2 Initial Jam
0012-0913
The machine identifies an initial jam if the top sensor or the delivery sensor detects the presence of paper when the main motor starts to rotate.
2.4.3.4.3 Cover Open Jam
0012-0914
The machine identifies a cover open jam if it detects that the front cover is open with the top sensor or the delivery sensor detecting the presence of paper (while
paper is being moved or the machine is not running a jam check).

[1] Fixing film unit
[2] Fixing heater
[3] Pressure roller
The machine's fixing system is an on-demand type, and its fixing assembly consists of the fixing film unit and the pressure roller: the fixing film has a built-in fixing
heater, thermistor, and thermal fuse.
The toner transferred to paper is heated by the fixing heater, which provides heat through the fixing film; the toner is forced under the pressure roller so that it is
fused into the fibers of the paper under both heat and pressure.
2.5.2 Protection Function
2.5.2.1 Protective Mechanisms
0012-0916
The machine is equipped with the following 3 types of protective mechanisms used to prevent its fixing heater from going awry.
1. protective mechanism by the CPU
2. protective mechanism by the fixing heater safety circuit
3. protective mechanism by the thermal fuse
1. Protective Mechanism by the CPU
The machine's CPU monitors the voltage of the fixing heater temperature detection signal from the main thermistor and the sub thermistor at all times, and
it cuts the power to the fixing heater if it finds that the fixing temperature appreciably exceeds a specific level.
When the fixing temperature abnormally increases and the voltage of the fixing heater temperature detection signal from the main thermistor drops to about
0.775 V (equivalent of 235 deg C) or less, the CPU causes the fixing heater drive signal to go Low and turns off the photo triac coupler, thus cutting power
to the fixing heater.
If the temperature of the fixing heater abnormally increases and the voltage of the fixing heater temperature detection signal from the sub thermistor reaches
about 2.779 V (equivalent of 320 deg C) or more, the CPU causes the fixing heater drive signal to go Low and turns off the photo triac couple, thus cutting
off the power to the fixing heater.
2. Protective Mechanism by the Fixing Heater Safety Circuit
The fixing heater safety circuit monitors the voltage of the fixing heater temperature detection signal from the main thermistor and the sub thermistor at all
times.
If the fixing temperature appreciably exceeds a specific level, the machine cuts off the power to the fixing heater regardless of the instructions from the CPU.
When the temperature of the fixing heater increases abnormally and the voltage of the fixing heater temperature detection signal of the main thermistor
reaches about 0.775 V (equivalent of 235 deg C) or less, the output of the comparator turns Low to turn off the relay, thus cutting off the power to the fixing
heater.
Likewise, if the temperature of the fixing heater increases abnormally and the voltage of the fixing heater temperature detection signal of the sub thermistor
reaches about 2.779 V (equivalent of 320 deg C) or more, the output of the comparator turns Low to turn off the transistor, thus turning off the relay and
cutting off the power to the fixing heater regardless of the relay drive signal from the CPU.
3. Protective Mechanism by the Thermal Fuse
If the temperature of the fixing heater increases abnormally and the temperature of the thermal fuse exceeds about 228 deg C, the thermal fuse starts to melt
to cut off the power to the fixing heater.
2.5.2.2 Detecting a Fault in the Fixing Assembly
0012-0917
The CPU identifies a fault in the fixing assembly for the following conditions (a. thorough g.) and operates as described:
1. the CPU causes the fixing heater drive signal to go Low to cut off the power to the fixing heater.
2. the CPU causes the relay drive signal to go Low to turn off the relay.
3. the CPU, if it detects a fault while printing is under way, discharges the paper being picked up or moved at the time, and immediately turns off the main motor,

scanner motor, and high-voltage system and puts the printer unit in an error state.
a) the reading of the main thermistor does not exceed 50 deg C within 2.34 sec after the start-up temperature control mechanism is started.
b) the CPU detects that the reading of the main thermistor remains 235 deg C or more for 1 sec continuously while fixing temperature control is under way.
c) the CPU detects that the reading of the main thermistor remains 100 deg C or less for 1.2 sec continuously while paper passage temperature control is under way;
or the CPU detects that the reading of the main thermistor remains 50 deg C or less for 0.3 sec continuously while between-sheets temperature control is under
way.
d) the CPU detects that the reading of the main thermistor remains less than 20 deg C for 0.3 sec continuously while fixing heater temperature control is under way.
e) the temperature of the main thermistor does not exceed 100 deg C within 20 sec after the start of start-up temperature control.
f) the CPU detects that the reading of the sub thermistor remains less than 35 deg C for 0.15 sec continuously while fixing heater temperature control is under way.
g) the CPU detects that the reading of the sub thermistor remains 320 deg C for 0.15 sec continuously while fixing heater temperature control is under way.
