Symbols Used
This documentation uses the following symbols to indicate special information:
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.
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.
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."

1.2.5 Safety
1.2.5.1 Safety of the Laser Light
Laser light can prove to be hazardous to the human body. The machine's laser unit is fully enclosed in a protective housing and external covers so that its light will
not escape outside as long as the machine is used normally.
1.2.5.2 CDRH Regulations
The Center for Devices and Radiological Health of the US Food and Drum Administration put into force regulations concerning laser products on August 2, 1976.
These regulations apply to laser products manufactured on and after August 1, 1976, and the sale of laser products not certified under the regulations is banned
within the Untied States. The label shown here indicates compliance with the CDRH regulations, and its attachment is required on all laser products that are sold
in the United States.

THIS PRODUCT CONFORMS WITH DHHS RADIATION
PERFORMANCE STANDARD 21CFR CHAPTER 1
SUBCHAPTER J.
1.2.5.3 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.)
Warning labels are affixed to the top cover of the laser scanner unit and the inner cover inside the front cover of this machine.
1.2.5.4 Safety of Toner
The machine's toner is a non-toxic material made of plastic, iron, and small amounts of dye.
Do not throw toner into fire. It may cause explosion.
Toner on Clothing or Skin
1. If your clothing or skin has come into contact with toner, wipe it off with tissue; then, wash it off with water.
2. Do not use warm water, which will cause the toner to jell and fuse permanently with the fibers of the cloth.
3. Do not bring toner into contact with plastic material. It tends to react easily.
1.2.5.5 Point to Note about Fire
It is dangerous to throw lithium batteries and parts and components containing flammable substances, such as cartridges, etc., into fire. Such parts and components
must be disposed of in accordance with local laws and regulations.

In identifying the original size, the data obtained in the original size identification process 1 is compared with the data obtained in the original size identification
process 2 to check whether these two pieces of data are identical.
Note that a wrong original size may be identified because the sensor output level does not change in the following cases:
- When the original is A3-sized black
- When the original is a book (its thickness does not allow the copyboard cover to close fully, making it difficult to detect the sensor level change).
- When the copyboard cover is not closed fully (the sensor level change is not detected after lapse of the above time-out time)

4.3.5 Dirt Sensor Control
The machine changes the original read position or corrects the read image depending on the presence/absence of dust on the stream reading glass or ADF platen
roller, thus preventing dust from showing up in the image. This control is performed only when the ADF is used and it is closed.
[Control Timing]
- At job end
- Immediately before scanning (one sheet at a time)
WMUPR
Dust detection control
[Description of Control]
- At job end (Dust detection)
The contact image sensor (CIF) checks the light reflected by the ADF platen roller surface at the read position for presence/absence of dust. After completion of a
job, dust detection is performed three times. First, dust detection is performed once at position A. If no dust is detected at position A, dust detection is performed
twice there. If no dust is detected, the original is scanned at position A. If dust is detected at position A, move to position B and dust detection is performed twice
at position B. If no dust is detected at position B, the original is scanned at position B. If dust is also detected at position B, move to position C and dust detection
is performed once at position C. If dust is also detected at position C, a relevant message is displayed on the operation panel. In this case, move back to position A
and the original is scanned at position A.
- At job start (Dust bypass)
Presence/absence of dust is detected at all points A, B, and C in this order at job end. The original is read at the point where least dust is detected.
The contact image sensor (CIS) does not move to detect dust.
The original is read at the position determined at job end or start. If presence of dust is detected there, the read image is corrected.

4.3.6.3 CMOS Sensor Output Gain Correction and Offset Correction
The analog video signals output from the CMOS sensor are corrected so that they will have a specific gain level (gain correction), and the output voltages generated
in the absence of incident light are also corrected so that they it will have a specific offset level (offset correction).
4.3.6.4 CMOS Sensor Output A/D Conversion
After completion of the above corrections, the analog video signals are converted to digital signals corresponding to individual pixel voltage levels by the A/D
converter.
4.3.6.5 Shading Correction (Outline)
The CMOS sensor outputs are necessary even for the following reasons even when the density of the original is uniform:
(1) Variation in sensitivity among CMOS sensor pixels
(2) Variation in light intensity of rod lens array
The machine performs shading correction to even out the CMOS sensor output.
There are two types of shading correction: shading adjustment performed in the Service mode and shading correction performed for each job.
4.3.6.6 Shading Adjustment
The machine measures the density of the standard white plate, and stores the measured density data. It then processes the stored data to use it as the target value for
shading correction.
4.3.6.7 Shading Correction
The machine performs shading correction for each scan. It measures the density of the standard white plate, and compares the measured value with the target value
stored in the shading correction circuit to use the difference between the two as the shading correction value. The machine uses this shading correction value to
correct the variation among CMOS sensor pixels when scanning the original, thus evening out the image density level.

5.3.1.4 Removing the Laser Scanner Unit........................................................................................................ 5-7
The laser scanner unit consists of a laser driver, scanner motor, and others. It is controlled by the signals from the DC controller PCB.
The laser driver operates the laser diode to emit light in response to the laser control signals and video signals from the DC controller PCB.
Laser beams are emitted, through a collimator lens and cylindrical lens, to the hexahedral mirror rotating at a constant speed.
Laser beam reflected by the hexahedral mirror focus on the photoconductor drum via the imaging lens and loop-back mirrors installed before the hexahedral mirror.
When the hexahedral mirror rotates at a constant speed, the photoconductor drum is scanned with laser beams at a constant speed.
When the photoconductor drum rotates at a constant speed and the photoconductor is scanned with laser beams at a constant speed, a latent image is formed on the
photoconductor drum.

5.2 Various Controls
5.2.1 Controlling the Laser Activation Timing
5.2.1.1 Laser Emission ON/OFF Control
The purpose of this control is to turn ON/OFF the laser diode (LD) in response to video signals.
The DC controller PCB sends laser control signals (CNTRL0, CNTRL1, and CNTRL2), which are used to switch between laser driver operation modes, to the laser
driver IC along with video signals (VDO1, /VDO1, VDO2, and /VDO2). The laser driver IC controls laser emission (ON/OFF) according to the combination of
CNTRL0, CNTRL1, and CNTRL2 signals.
The following table shows combinations of laser control signals (CNTRL0, CNTRL1, and CNTRL2).

5.2.1.3 Horizontal Synchronization Control
The purpose of this control is to adjust the position where scanning starts in the horizontal direction (main scan direction) of the image with reference to the horizontal synchronization signal (/BD) sent from the BD sensor in the laser scanner. The horizontal synchronization signal is also used as a vertical synchronization
signal to recognize the leading edge of paper. Upon detection of arrival of the fed paper at the prescribed position, the DC controller PCB starts sending the /BD
signal to the image porcessor PCB. The image processor PCB recognizes the leading edge of paper at the start of the continuous /BD signal; it recognizes the trailing
edge of paper at the end of the continuous /BD signal.
About Generation of BD Signal
The BD sensor on the BD circuit board receives only the beam of laser B; it does not receive the beam of laser A. The BD signal is generated from the beam of
laser A.
5.2.2 Controlling the Intensity of Laser Light
5.2.2.1 Automatic Photocurrent Control (APC)
The purpose of this control is to monitor the laser beam emitted to the photodiode on the laser driver circuit board in order to adjust the light quantity.
5.2.3 Controlling the Laser Scanner Motor
5.2.3.1 Laser Scanner Motor Control
From the moment the laser scanner motor starts to the moment it reaches the target revolution speed, the revolution speed is controlled with reference to the laser
scanner motor revolution speed signal (FG signal). After the target revolution speed is reached, the revolution speed is controlled so that the BD cycle and the laser
scanner motor revolution cycle are in the same phase.
The revolution speed of the laser scanner motor is controlled using an acceleration signal (ACC signal) and deceleration signal (DEC signal).

5.2.4 Controlling the Laser Shutter
5.2.4.1 Laser Shutter Control
When the drum unit is drawn out, the interlocked laser shutter moves down, shutting off the laser beam path. When opening of the front cover or left door is detected,
the laser scanner motor and laser outputs turn off.

6.5.2 Charging Mechanism
6.5.2.1 Primary Charging Bias Control
With the primary charging bias method, the drum is charged directly by the charging roller. In addition to a DC bias, an AC bias is applied to the primary charging
roller to stabilize charging. When the drum is charged, both AC and DC biases are applied. When the drum is discharged, only the AC bias is applied.
The ASIC on the DC controller PCB outputs the primary bias drive signal (/PRACFOT), primary AC bias ON/OFF signal (/PRACON), primary DC bias drive
signal (/PRDCFOT), and primary DC bias output level signal (/PRDCPWM) to apply the voltage generated by superimposing the primary AC bias over the primary
DC bias to the primary charging roller.
The primary AC bias is detected by the primary AC bias current detection circuit, and is fed back to the AC generator circuit via the comparison circuit.
The primary DC bias is detected by the primary DC bias current detection circuit, and is fed back to the DC generator circuit via the comparison circuit. Thus, this
machine controls the primary DC bias voltage. The primary DC bias voltage changes with the developing DC bias voltage according to the image density information sent from the image processor PCB.

6.6.2 Developing Bias Control
A DC bias and an AC bias are applied to the developing cylinder.
The ASIC on the DC controller PCB outputs the developing AC bias drive signal (/DVACFOT), developing AC bias ON/OFF signal (/DVACON), developing DC
bias drive signal (/DVDCFOT), and developing DC bias output level signal (/DVDCPWM) to apply the voltage generated by superimposing the developing AC
bias over the developing DC bias to the developing cylinder.
To prevent fogging of the drum, a DC bias higher than usual applied except during image formation and when the developing AC bias is applied for warm-up
rotation.
The developing DC bias is detected by the developing DC bias detection circuit, and is fed back to the DC generation circuit via the comparison circuit, thus controlling the DC bias voltage. The developing DC bias voltage changes with the primary DC bias voltage according to the image density information sent from the
image processor PCB.
The remaining toner level is detected during warm-up rotation and when the developing AC bias is applied for printing. The remaining toner level detection signal
(TNRCHKT) sampled from the antenna (for remaining toner level check) in the developing assembly is compared with the reference signal (TNRCHKD) received
from the developing bias detection circuit.

6.8.2 Controlling the Transfer Bias
6.8.2.1 Transfer Roller Bias Control
A negative bias, sheet-to-sheet bias, or positive bias is applied to the transfer charging roller according to the type of sequence.
The negative bias is applied at the prescribed timing to moves the toner from the transfer charging roller to the photosensitive drum for cleaning.
The sheet-to-sheet bias is lower than that applied during printing and it is applied at the prescribed timing to prevent the toner remaining on the photosensitive drum
from adhering to the transfer charging roller.

7.2.3 Other Jams
7.2.3.1 Door Open Jam
Door Open Jam
The door is opened when paper to be printed is in the paper feed path.
7.3 Cassette Pick-Up Unit
The paper picked up from the cassette is fed to the registration roller using the vertical path roller driven by the main motor (M204). The registration roller is not
rotating when paper reaches there, so an arch is formed at the leading of the paper to prevent skewing. The DC controller PCB turns on the registration clutch
(CL203) at the prescribed timing to transfer the main motor rotation to the registration roller, thus feeding the paper to the delivery tray through the transfer, sepa-
ration, fixing, and delivery assemblies.
7.3.2 Cassette Pickup Operation
Rotation of the pickup roller is controlled by the pickup roller drive gear, which transfers the drive power of the main motor (M204) to the pickup roller drive shaft,
and the cassette pickup solenoid (SL202). When the main motor starts rotating, the interlocked relay gear also starts rotating. At this time, the pickup roller drive
gear is not driven because its toothless portion is positioned at the relay gear and therefore these gears are not engaged with each other.
1) The DC controller PCB issues a cassette pickup solenoid drive signal (CSTFD). When the solenoid is turned on, the control arm pushes the cam to rotate the
pickup roller drive gear slightly.
2) When the pickup roller drive gear is engaged with the pickup roller shaft gear, drive power is transferred to the pickup roller shaft gear and consequently the
pickup roller starts rotating.
3) When the feed roller drive gear is engaged with the feed roller shaft gear, drive power is transferred to the feed roller shaft gear and consequently the feed roller
starts rotating.
4) When the pickup roller rotates once, the toothless portion of the pickup roller drive gear comes to the position of the relay gear and consequently drive power of
the main motor is not transferred, stopping the rotation of pickup and feed rollers.
5) The picked up paper is fed to the registration roller through the vertical path roller.
7.3.3 Cassette Paper Size Detection
The size of the paper in the cassette is detected by the DC controller PCB when the user changes the position of the cassette paper size lever. When the cassette is
inserted in the iR host machine, the paper size lever pushes the paper size switches provided in the iR host machine to allow the DC controller PCB to detect presence
of the cassette and the size of paper. Paper size switches are arranged as shown below. Paper sizes are determined by the combinations of the switches pushed by
the paper size lever.

7.4 Manual Feed Pickup Unit
a. Multi Manual feed Pickup Control
The manual feed pickup mechanism picks up sheets of paper in succession from the multi manual feed tray. The sheets of paper stacked in the tray are raised against
the manual feed pickup roller by the inner plate. The manual feed pickup roller is driven by the main motor (M204) via the manual feed pickup solenoid (SL202)
and gears. Only one sheet of paper is picked up by the combination of the manual feed pickup roller and manual feed pickup paper separation pad, and then fed to
the registration roller. These operations are performed for each sheet to be picked. The user must set the size of the paper in the multi manual feed tray using the
operation panel, or the user must register a fixed size in the user mode.
b. Inner Plate Lift Operation
During standby, the inner plate is at the down position with it held by the cams provided at the front and back of the manual feed pickup roller shaft. Rotation of
the pickup roller rotates the interlocked cams to lift the inner plate, raising the sheets of paper (loaded in the manual feed tray) against the manual feed pickup roller.
On the opposite side of the pickup roller is mounted a separation pad that separates only one sheet of paper from others and feeds it to the next section.
c. Manual feed Tray Pickup Drive Mechanism
pickup solenoid drive signal (MFPD) sent from the DC controller PCB. Rotation of the main motor drives the pickup drive power transfer gear. The DC controller
PCB issues a manual feed pickup solenoid drive signal (MFPD). When the solenoid turns on, the stopper operates to rotate the pickup roller once. Next, the stopper
operates again to stop rotation of the pickup roller.
7.4.2 Post-pickup Control after Multi Manual Feed Pickup
Paper pickup operation ends when paper is pressed against the registration roller. After this, the registration roller starts rotating and the multi manual feed pickup
clutch turns on. This clutch turns off after feeding the paper by the distance equivalent to the paper size - 126.7 mm (*1) -5 mm (*2).
*1 Distance that paper is fed from the multi pickup roller to the point where the registration sensor turns on.
*2 Paper is post-fed to the point which is 5 mm to the training edge.
When the paper size is not specified, paper is post-fed by the distance equivalent to the multi paper feed enabled size (148 mm in longitudinal direction).
Minimum post-feed distance: 148 mm - 126.7 mm -5 mm = 16.3 mm

8.2.1.1 Controlling the Fixing Film Speed
[1] FILM_SENS
The rotation cycle is measured with reference to the mark provided at the end of the fixing film to rotate the fixing drive motor at the optimum speed, thus keeping
the paper feed speed constant. Measurement of the cycle of each rotation (excluding the initial rotation and post-rotation) of the fixing drive motor starts when 1
second lapses after the motor starts rotating and ends when the trailing edge of the last sheet has passed through the fixing nipper.
[1] Film rotation detection signal (FILM_SENS): Set to 1 and 0 alternately when the fixing film is rotating.
[2] Rotation cycle measurement mark
8.2.2 Controlling the Fixing Film Temperature
The surface temperature of the fixing heater is detected to control the fixing heater drive signal so that the fixing heater temperature becomes the target temperature.
The temperature of the fixing heater is detected by the thermistor (TH1/TH2) provided on the fixing heater. If the surface temperature rises, the resistance of the
thermistor lowers and the voltage of the fixing heater temperature detection signal (M_TH/S_TH) also lowers.
The CPU on the DC controller monitors the voltage of the M_TH/S_TH signal to control the fixing heater 1 drive signal (H1DRV) and fixing heater 2 drive signal
(H2DRV). These two voltages are generated based on the zero crossing detection signal which is output from the heater control circuit. The CPU controls these two
signals to adjust the fixing heater temperature to the prescribed value.
8.2.2.2 Controlling the Fixing Film Temperature
This machine performs fixing temperature control according to the fixing heater temperature as mentioned below.
1) Warm-up temperature control
Upon receipt of a print command from the DC controller, the fixing heater heats to the temperature below the target paper-present section temperature.
2) Paper-present section temperature control
The fixing heater temperature is adjusted to the target paper-present section temperature according to the combination of the paper size, number of sheets fed,
fixing mode, and temperature detected by the fixing main thermistor.
3) Sheet-to-sheet temperature control
The fixing heater temperature is held relatively below the target paper-present section temperature to prevent the paper-absent section temperature from rising
between sheets.
4) Down sequence
The temperature may detect an abnormally high temperature during continuous printing. If the sub-thermistor detects a temperature equal to or higher than 275
deg C, the sheet-to-sheet distance is increased to prevent the paper-absent section temperature from rising. If the sub-thermistor detects a temperature equal to
or lower than 220 deg C in the down sequence, normal control resumes.
5) Cooling mode
If printing is performed using wider sheets (*1) after printing is performed using narrower sheets in the continuous print mode, fixing offset may occur due to
the difference in temperature between the edge and center. If the sub-thermistor detects a temperature equal to or higher than 130 deg C, paper feed and printing
stop to prevent the temperature from rising at the edge. If the sub-thermistor detects a temperature equal to or lower than 130 deg C or two or more minutes lapse,
normal control resumes.
*1: The large size is a paper of which the width is 10 mm larger than the previous job.
8.2.2.3 Target Temperatures by Mode
This machine controls the fixing temperature according to the "media type" selected in the user mode and the "target temperature" set in the "special mode."
The correspondence between each mode and target temperature is as follows:

target temperature is lowered in 5 deg C steps.
*2: Number of sheets controlled at the initial target temperature. If it is exceeded, the target temperature is lowered. The prescribed number of sheets varies with
the paper size.

High temp.
This machine is provided with the following four protection functions to prevent the fixing heater from overheating:
1) The CPU monitors the thermistor (TH1) voltage. If the thermistor (TH1) voltage is abnormal, the CPU judges that the fixing heater is faulty and turns off the
relay (RL1). At the same time, the CPU notifies the DC controller of occurrence of the fixing heater failure.
2) If the temperature of the fixing heater rises abnormally and the thermistor (TH1) detects a voltage lower than about 0.7 V (equivalent of 240 deg C), the fixing
heater high temperature detection circuit cuts off the power supplied to the fixing heater.
3) If the temperature of the fixing heater rises abnormally and the thermo switch (TP1) detects a temperature higher than 244 deg C, the thermo switch turns off to
cuts off the power supplied to the fixing heater.
Failure Detection
The CPU performs error detection at intervals of 40 msec. If any one of the cases a to d occurs, the CPU stops the machine completely. To restart the machine,
remove the cause of the failure and carry out initial rotation. If a failure is detected, an error code "EXXX-YYYY" (XXX stands for an error code and YYYY stands
for a detail code) is displayed on the operation panel.
a. Failure at startup
1) The main thermistor has detected temperatures lower than 30 deg C continuously for 400 or more msec since 1 second lapsed after energization of the fixing
heater.
2) The main thermistor has detected temperatures lower than 70 deg C continuously for 400 or more msec since 2 seconds lapsed after energization of the fixing
3) The sub-thermistor has detected temperatures lower than 75 deg C continuously for 400 or more msec since 5 seconds lapsed after energization of the fixing
4) The temperature rise detected by the main thermistor is less than 5 deg C when energization of the fixing heater starts, when the temperature detected by the main
thermistor is less than 100 deg C, or when 1 sec has lapsed since start of energization.
5) The main thermistor has detected temperatures less than 115 deg C continuously for 400 or more msec since 1 second has lapsed after detection of 100 deg C.
8) The target printing temperature is not reached when 30 seconds have lapsed since start of the initial rotation.
b. Low temperature detection during temperature control
During temperature control, the main or sub thermistor has detected low temperatures continuously for 400 or more msec after the target temperature was reached.
c. Abnormally high temperature detection
1) The main thermistor has detected 240 C deg irrespective of whether the fixing heater is of or off.
2) The sub thermistor has detected 295 deg C irrespective of whether the fixing heater is of or off.
3) An abnormally high temperature has been detected in the ASIC irrespective of whether the fixing heater is of or off.
d. Drive circuit failure
1) The zero crossing signal frequency of the power supply has not been detected during initial rotation.
2) During temperature control, no zero crossing signal has been input for 3 seconds.
3) A triac short circuit has been detected in the ASIC.

9.3 Power Supply System
9.3.1 Power Supply
When the main power switch (SW1) is turned on, AC power is supplied to the low-voltage power supply circuit in the power supply PCB.
The low-voltage power supply circuit supplies +3.3 V, +5 V, and +24 V to operate the machine.
+24 V is supplied to the motors, fan, electromagnetic clutch, solenoid, etc. +5 V and +3.3 V are supplied to the sensor, etc.
There are two types of +24 V voltages: +24 V which is normaly supplied from the low voltage power supply and +24 VR which is cut off when the front cover or
the left door is opened. The +24 VR also plays the role of a door open detection signal (DOPEN). This signal allows the CPU to detect that the front cover or the
left door has opened.

12.1.6 Others
If a machine is brought from a cold to warm room, its inside can start to develop condensation, leading to various problems.
a. condensation on the BD sensor is likely to cause problems associated with E100
b. condensation on the dust-proof glass is likely to cause poor image density in sub scanning direction
c. condensation on the contact sensor of the reader unit or on the copyboard glass can cause light images
d. condensation on the pickup or feed guide can cause paper feed problems
If the problem given in d. above has occurred, dry wipe the units in the feed system. Do not open the package containing a toner cartridge, developing unit, or drum
unit right after it has been brought in from a cold to warm place to avoid condensation. Be sure to leave it alone for a while (1 to 2 hr), opening it after it has become
fully used to the temperature of the site.

13.5 FAX Error Codes
13.5.1 Outline
13.5.1.1 Error Code Outline
An error code is used to indicate a fault in a machine, and is indicated in the machine's LCD or reports, showing the nature (symptoms) of the fault. Using the error
code, the user or the service man can readily find out how to correct the fault by simply referring to the User's Manual or service manual.
An error code may be either of the following two types:
User Error Codes
A fault indicated as a user error code is one that can easily be corrected by the user, as by operating the machine. It takes the form of "#+number."
Service Error Codes
If a fault calls for a service man for correction, it is indicated as a service man error code in the form of "##+number" or "SYSTEM ERROR E+number."
A service error code expressed in the form of "##+number" will not appear on the LCD, Error Tx Report, or Activity Report while the machine remains
in factory default state. To check a service error code, shift bit 0 of service soft switch #1 SSSW SW01 to '1'.
Display only the error codes which are newly incorporated in this machine as well as which require remedies unique to the product. For the causes and
countermeasures of other error codes, refer to the separate G3/G4 Facsimile Error Code List (Rev. 2).

Transfer bias pressure reduction mode
Developing assembly idling mode
Black belt addition mode
Post-rotation reduction mode
Flicker reduction mode
Silent mode
Terminal temperature rise noise reduction mode
Select whether to enable or disable transfer bias pressure reduction mode.
Select "Enable" to avoid image defects (black spots) produced by transfer bias leaks occurring in a low-pressure region, such as one at a high altitude. This setting
regulates the transfer bias to keep it from exceeding a predetermined level during printing.
Select whether to enable or disable developing assembly idling mode. Select "Enable" to drive the main motor for a specified period of time to apply idling and
developing bias (AC + DC) to prevent the thinning of the image density when the unit is installed or the developing unit is replaced in a low-temperature, lowhumidity region. This mode works only on a new developing assembly and before a toner cartridge is loaded.
Select whether to enable or disable black belt addition mode. If the user uses paper that causes fixed toner on paper to be fused and adhered to drum, selecting
"Yes" will clean the drum by forming a black band on the drum surface during the reverse rotation which is performed after printing on 50 sheets.
Implementation of this mode could result in a drum life falling short of its life expectancy.
Select whether to enable or disable post-rotation reduction mode. Selecting "Enable" will reduce the noise caused by the polygon motor by stopping the motor
immediately after post-rotation.
Select whether to enable or disable flicker reduction mode. Select "Enable" and enter a count to modify fusing temperature control to cancel fluorescent flicking
during printing.
Implementation of this mode would degrade the throughput.
Select whether to enable or disable silent mode. Select "Enable" to modify the registration loop amount and thus reduce noises or squeaks the registration rollers
produce after picking paper from the individual paper inlets.
Select whether to enable or disable noise reduction mode during terminal temperature rises. Select "Enable" to start slowdown at a temperature lower than normal
when printing on smaller-sized paper than B4. Slowdown control thus enabled prevents the thermal degradation of the fusing film grease, assuring smooth sliding
among the fixing film, heater and film guide to cut squeaks.
Inhibit automatic delivery tray replacement while running Enable
Halt stapling job when out of staples
Inhibit tray full indication while the stapled document
count is exceeded
Select whether to inhibit automatic delivery tray replacement while running jobs with an inner two-way tray mounted in position. Select "Enable" to inhibit automatic tray replacement.
Select whether to halt stapling job when a finisher installed has run out of staples. Select "Enable" to halt staple jobs when the finisher has run out of staples.
Select whether to display a tray full message when the maximum allowable stapled document count is exceeded with a finisher installed. Select "Enable" not to
display the message.
