INTRODUCTION
iv
The following rules apply throughout this Service Manual:
1. Each chapter contains sections explaining the purpose of specific functions and the re-
lationship 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 sig-
nal.
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 ma-
chines 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 Ser-
vice Manual and all relevant Service Information bulletins and be able to identify and isolate
faults in the machine.

When the self-diagnostic program ends normally, the boot program also stored in the boot
ROM will start up. The boot program reads the system software from the HDD into the sys-
tem area of the SDRAM.
When the write operation ends, the system software in the SDRAM starts up to initialize
the various parts of the machine, at the end of which the control panel will indicate the nor-
mal operation screen and, at the same time, the Start key LED changes from red to green to
indicate that the machine is ready to accept a job.
The machine’s system software consists of multiple modules, and those modules that are
needed for a specific task in question will be called into the system area of the SDRAM for
use.

2.2 Input Image Processing
The image data from the reader unit is processed for the following:
2.2.1 Image Data from the Reader Unit
The image signals from the reader unit are 8-bit, 256-gradation intensity image signals
which have been subjected to shading correction.
The signals arrive from two signal lines (for even- and odd-numbered pixels).
2.2.2 Enlargement/Reduction (main scanning direction)
An image is enlarged or reduced by processing image data when writing it into or reading
it from image memory.
2.2.3 Edge Emphasis
For each mode (text, text/photo, print photo, film photo), edge emphasis is executed so as
to increase sharpness while suppressing moire.
2.2.4 Editing
The machine provides various editing functions: negative/positive reversal, mirror, fold.
2.2.5 Density Conversion (LUT)
In this block, the intensity image signals are converted into density image signals, and
processing is executed so as to enable the best output density curve for a specific mode in
question.
a. LOG Conversion
Using a LOG conversion table, intensity image signals based on reflected light are con-
verted into density image signals based on density data.
b. Density Adjustment (F-value conversion)
The F-value table most suited to the setting of the Density key in the control panel is used
to adjust the density; it, however, will not be executed in memory copy mode.
c. Density Correction (γγ
γγ
γ conversion)
The γ conversion table best suited to each specific mode (test, text/photo, print photo, film
photo) is used to correct density.

CHAPTER 2 MAIN CONTROLLER
2-9 S
2.2.6 Binary Processing (error diffusion method T-BIC)
In the error diffusion method (T-BIC), the texture is controlled to process the data for op-
timum printing effects; 8-bit image density signals of each mode (text, text/photo, print
photo) are converted into 1-bit image density signals (binary).
2.2.7 Binary (dither screen method)
In the dither screen method, the texture is controlled to process the data for optimum
printing effects; 8-bit image density signals for film photo mode are converted into 1-bit im-
age density signals (binary).
Although expressed in binary, the resulting signals enable reproduction in 256 gradations
(dither screening of 40×40 pixels).
2.3 Image Memory Control
The image data after binary processing is controlled for the following:
2.3.1 Compression/De-Compression, Rotation, and Enlargement/Reduc-
tion
The binary data generated as the result of the foregoing processes is subjected to the fol-
lowing: compression/de-compression (for electronic sorting), rotation, resolution conver-
sion.
2.3.2 SDRAM
The image data subjected to image memory control is temporarily stored in SDRAM.
2.3.3 HDD
The HDD functioning as an image server is used to store image data for the Box function.

2.4 Output Image Processing
The output image data to the printer unit is subjected to the following processing:
2.4.1 Smoothing
a. When Generating Read Images
In the case of text or test/photo mode, the input image of 600×600 dpi is converted into
1200*×600 dpi by means of smoothing.
*Equivalent.
In smoothing, image data is compared against a template consisting of several combina-
tions of pattern matrixes for replacement of selected pixels.
In addition, notch processing is also executed at the same time as a pattern unique to read
image.
b. When Generating Printer (PDL) Images
The image data is subjected to the type of smoothing best suited to PDL, in which
600×600 dpi is converted into 2400*×600 dpi.
*Equivalent.
2.4.2 Binary-Binary Density Conversion (read image output only)
This processing is used as an auxiliary means for adjusting the density of images.

5 New Functions
5.1 Hard Disk Spool
In hard disk spool, print data is not directly sent to memory for printing, but spooled on
the HDD before printing, thus releasing the application program running on the host PC
sooner than otherwise.
When this function is used, a print job from the PC is stored in the spool area of the
HDD. (The spool area is as large as about 300 MB.) Once spooled, the jobs are then sent to
the RIP processing block in the order they have been received.
The jobs are removed from the spool as they are printed, and as many as 100 jobs may be
spooled at a time.
The following diagram shows the flow of data, from spooling on the HDD to execution:

5.2 SMB Printing
SMB has been developed so as to use NetBIOS, which specifies an address by means of a
computer name, for use solely with a specific protocol. SMB over TCP/IP is designed for
use in combination with the TCP/IP protocol, enabling the machine to print data directly
from Windows 95/98/ME without going through a Windows NT/2000 sever as is in the case
of LPR printing and without the need for an LPR utility. (A Windows work group may be
made use of, but Windows NT/2000 cannot be called into the domain.)
On a TCP/IP network an address must be specified by means of an IP address, not the
name of the computer in question, requiring conversion of a computer name into an IP ad-
dress. If a WINS (Windows Internet Name Service) server exits on the network, the function
may also be made use of. If it does not exist or is not used, the PC will contact all devices
on the network to find out the IP address of the machine before it sends a print job to the
machine.

in advance of the delivery of the machine:
1. There must be a power outlet that may be used exclusively for the machine and rated as
indicated (±10%).
2. The temperature of the room must be between 7.5° and 30°C (59° and 86°F) and humid-
ity, between 5% and 80%. Avoid areas near a water faucet, water boiler, humidifier, or
refrigerator.
3. The site must not be near a source of fire or must not be subject to dust or ammonium
gas. If the site is exposed to direct rays of the sun, provide curtains.
4. The level of ozone generated by the machine in operation will not affect the health of
the individuals around it. Nevertheless, some may find the odor unpleasant, requiring
good ventilation of the work place.
5. The floor of the site must be level so that the feet of the machine will remain in contact
and the machine itself will remain level.

2 Unpacking and Installation
2.1 Before Starting the Work
Keep the following in mind for the work:
1. If the machine is brought in from a cold to warm place, its pickup/feed-
ing assembly can develop condensation, leading to image faults. Leave
the machine alone for at least one hour, and start the work after the ma-
chine has become used to the room temperature.
The term condensation refers to the symptom that occurs when a piece of
metal is brought in from a cold to warm place, cooling the vapor in the
air rapidly and turning it into droplets of water on the metal surface.
2. The machine weighs about 80 kg. Be sure to work in a group of four.

A loop-back address is returned before it reaches the network PCB; therefore, executing
PING using it will enable a check on the TCP/IP settings made on the machine.
1) Enter the loop-back address (127.0.0.1) in the PING field.
• If ‘NG’ is indicated, check the TCP/IP settings of the machine once again, and execute
PING once again.
• If ‘OK’ is indicated, go to 2.12.3.
2.12.3 Making a Check Using a Local Host Address
The local host address is the IP address of the machine, and executing PING using it will
enable a check on the network PCB (it is retuned after it reaches the network PCB).
1) Enter the IP address of the machine in the PING field.
• If ‘NG’ is indicated, perform the following check/correction, and execute PING once
again:
a. If the IP address of the machine is wrong, check the IP address settings made on the ma-
chine once again, or find out if the IP address assigned to the machine is correct or not
by consulting the user’s system administrator.
b. If the network has faulty connection, check the connector of the network PC for connec-
tion.
c. If the network PCB is faulty, replace the network PCB.
• If ‘OK’ is indicated, suspect a problem in the user’s network environment; report to the
user’s system administrator, and ask for corrective measures.

The major functions of the original exposure system are as follows:
Description
Xenon lamp
In book mode: by moving the scanner.
With ADF in use: by stream reading while holding the No. 1
mirror base fixed in position.
By scanner HP sensor (PS400)
[1] Using the Copyboard: 25% to 800%
• In main scanning direction, image processing is per-
formed by the controller unit.
• In sub scanning direction, the speed of the No. 1 mirror
base is changed (50% or higher and lower than 400%),
in addition, the image data is processed by the control-
ler unit (lower than 50% and 400% or higher).
[2] Using the ADF: 25% to 200%
• In main scanning direction, the image data is processed
by the controller unit.
• In sub scanning direction, the speed at which the origi-
nals are moved is changed (50% or higher and lower
than 200%), in addition, the image data is processed by
the controller unit (lower than 50%and 200% or
higher).
The No.1/No.2 mirror base is controlled by means of a step-
ping motor (M400).
Lens array (fixed in position)
[1] Turned on by an inverter circuit.

[1] When the copyboard cover is used, the ratio may be between 25% and 800% and the
speed of the scanner is controlled.
[2] When the ADF is used, the ratio may be between 25% and 400% and the speed of
moving the originals is controlled.
1.3.1 Changing the Reproduction Ratio in Main Scanning Direction
For main scanning direction, the original is read at 100% (for both copyboard and ADF);
the size is changed by processing data in the main controller unit.
[1] To reduce, data units are skipped when writing image data to the line memory.
[2] To enlarge, data units are read multiple times when reading image data from the line
memory.
1.3.2 Changing the Reproduction Ratio in Sub Scanning Direction
For sub scanning direction, the speed of the scanner/movement of the original is changed.
However, for a reduction between 25% and 49% and enlargement between 401% and 800%,
data processing in the main controller assembly is also used in combination.
[1] For enlargement, the speed of the mirror/original is reduced from that used in Direct:
e.g., at 200%, the speed is 1/2 of the speed used in Direct.
[2] For reduction between 50% and 99%, the speed of the mirror/original is increased;
e.g., at 50%, the speed is twice as high as that used in Direct.
F02-103-01
[3] To reduce to between 25% and 49%, the image data read at 50% and 98% is subjected
to skipping (1/2) in the main controller unit.
[4] For an enlargement between 401% and 800%, image data read at 200% to 400% is
sub-jected to repeating (doubling) in the main controller assembly.

3 Controlling the Scanning Lamp (LA2)
3.1 Outline
The system used to control the scanning lamp is constructed as follows and the items of
control include the following:
[1] Turning on and off the scanning lamp.
[2] Monitoring the scanning lamp for errors.
F02-301-01
3.2 Scanning Lamp
The machine’s scanning lamp is a xenon lamp of a non-electrode discharge type, in which
xenon gas is sealed in a tube.
On the outside of the glass tube, two electrodes are arranged parallel to the tube axis, and
the inner side of the glass tube is coated with fluorescent material.
The internal gas discharges and, as a result, the fluorescent material glows when a high-
frequency voltage is applied across the electrodes.
F02-302-01
3.3 Turning On/Off the Lamp
The scanning lamp is turned on/off in response to the drive signal (LAMP_ON) from the
CPU on the reader controller PCB. When the signal is generated, the inverter generates a
high-frequency voltage using the drive voltage (+24 V) supplied by the reader controller
PCB to turn on the xenon tube.

3.4 Detecting an Error
The reader controller circuit generates the error signal (INV_ERR) in response to an error
(e.g., output open, short circuit, leak) in the inverter circuit. A fault in the lamp (low inten-
sity, activation failure) will be identified as an activation error caused by lack of intensity
during initial activation (e.g., at time of shading correction).

It is used to indicate a fault in the inverter PCB.
E225
It is used to indicate a fault in the scanning lamp (xenon tube).

4 Detecting the Size of Originals
4.1 Outline
The machine automatically identifies the size of originals based on the combination of in-
tensities measured by reflection type sensors and CCD at specific points.
• For main scanning direction, the CCD is used to take measurements (if AB, 4 points; if
Inch, 2 points).
• For sub scanning direction, a reflection type photosensor is used (1 point).
4.2 Points of Detection
For main scanning direction, the No. 1 mirror base is moved to the following points in re-
lation to the position of the original to measure the intensity at each point.
For sub scanning direction, on the other hand, measurements are taken while holding the
sensor in place at a specific point.
F02-402-01
4.3 Outline of Detection
The machine identifies the size of originals in the following two steps:
[1] Detecting External Light (main scanning direction only)
While keeping the scanning lamp off, the CCD level at each point of detection in main
scanning direction is measured. A point at which external light is detected will be iden-
tified as indicating the absence of an original, enabling the identification of the width
of an original.
[2] Detecting the Sensor Output Level
The scanning lamp is turned on, and the CCD level at each point of detection in main
scanning direction is measured. In addition, the reflection type photosensor in sub
scanning direction is turned on to measure the sensor output.
The combination of these output measurements is used to identify the size of the origi-
nal. For specific movements, see the pages that follow.

When the copyboard cover is brought
down to 25°, the Copyboard cover sensor
detects the “closed” state, and original size
detection starts.

lamp is turned on, and the CCD checks for
reflected light (4 points).
For sub scanning direction, the original
sensor starts detection.
[5] The copyboard cover is fully closed.
The changes in the output level of each
sensor are monitored until the copyboard
cover is fully closed. The absence of a
change is identified as indicating the ab-
sence of paper, and the size of the original
is identified based on the combination of
changes in level at five points (T02-404-

2 Analog Image Processing
2.1 Outline
Analog image processing is performed by the CCD PCB and the reader controller PCB,
which has the following major functions:
[1] Drives the CCD.
[2] Corrects the gain in the CCD output, corrects offset.
[3] Performs parallel/serial conversion of CCD output.
[4] Performs A/D conversion of CCD output.
F03-201-01
2.2 Driving the CCD
The machine’s CCD sensor is a single-line linear image sensor, and is composed of 7450
pixel photo cells.
The signals subjected to phtoconversion in the light-receiving segment are sent out in two
types of analog signals: even-number (EVEN) pixels and odd-number (ODD) pixels.

2.3 Gain Correction and Offset Correction of the CCD Output
To correct discrepancies in the efficiency of photoconversion among pixels, the analog
video signals from the CCD are corrected: in gain correction, the rates of amplification are
standardized; in offset correction, on the other hand, the output voltage in the absence of in-
coming light is set to a specific level.
2.4 A/D Conversion of the CCD Output
The analog video signals of odd-number and even-number pixels after correction are con-
verted into 8-bit digital signals that correspond to specific pixel voltage levels by the A/D
converter.

3 Digital Image Processing
3.1 Outline
Digital image processing is performed by the reader controller PCB, which has the fol-
lowing major functions:
[1] Shading correction
[2] Auto density adjustment (AE)
F03-301-01
3.2 Shading Correction
3.2.1 Outline
The output of the CCD will not necessarily be uniform because of the following factors
even if the density of the original in question is perfectly uniform:
1) The level of sensitivity of a CCD pixel differs from that of another.
2) The level of penetration of light differs between the center and the periphery of a lens.
3) The intensity of the scanning lamp differs between the middle and the ends of the
lamp.
4) The scanning lamp is subject to deterioration.
Shading correction is executed to correct discrepancies in the output of the CCD, and it
may be of either of the following two: shading adjustment used to determine a target level in
service mode and shading correction executed when scanning each original.
To make up for the fluctuations in the intensity of light occurring at short intervals, edge
area gain correction is also executed.

3.2.2 Shading Adjustment
In this adjustment, the density of white paper and that of the standard white plate are mea-
sured, and the results are stored in memory.
The data is computed for use as the target level during shading correction. The adjustment
is designed for service mode and is used upon installation of the machine, after replacement
of the scanning lamp, or when correcting changes in the intensity of the scanning lamp oc-
curring over time.
3.2.3 Shading Correction
This correction is executed each time an original is scanned. The density of the standard
white plate is measured and the result is compared against the target value stored in the
shading correction circuit. The difference is used as the shading correction value, which will
be used to correct the variation in CCD pixels, thereby ensuring a specific level of image
density.

3.2.4 Edge Gain Correction (ADF in use)
In stream reading with the ADF in use, the No. 1 mirror base is fixed in position. To
check for changes in the intensity of the scanning lamp, the edge gain correction plate (gray;
mounted at the edge of read position) is read, and a gain that enables the attainment of a
specific intensity is computed.
The result is used to correct the data which otherwise would be affected by changes in the
intensity of light.

3.3 Auto Density Adjustment (AE)
3.3.1 Outline
As in the case of a newspaper, some originals have a dark background. Auto density cor-
rection is executed to reproduce the information (text, graphics) of such originals by remov-
ing the background.
This adjustment is enabled in density auto mode or when text mode is selected and data is
processed by the ABC circuit.
3.3.2 ABC Circuit
A colored background is identified as being white by changing the height of the dynamic
range according to the chromatic level of the background as shown in the following figure
for the CCD output level (8-it) of digital image signals (A/D converted).

1 Safety
1.1 Safety of Laser Light
Laser light can prove to be harmful to the human body. The machine’s laser system, how-
ever, is sealed inside a protective housing and external covers to prevent leakage of laser
light to its outside, ensuring the safety of the user as long as the machine is used for its in-
tended functions.
1.2 CDRH Ordinances
The Center for Devices and Radiological Health (CDRH) of the US Food and Drug Ad-
ministration put into force ordinances related to laser products on August 2, 1976.
These ordinances apply to laser products manufactured on and after August 1, 1976, and
sale of laser products is prohibited within the US unless they bear a certificate of compli-
ance.
The following is the label that indicates compliance with the CDRH ordinances, and it
must be found on all laser products sold in the US.

1.3 Handling the Laser System
You must take extra care when servicing the area around the machine’s laser system, as by
not bringing a high-reflectance screwdriver into the laser path.
Take such precautions as removing the watch and rings before starting the work (to pre-
vent reflection of laser light to the eye).
The machine’s laser light is red, and covers that can reflect laser light are identified by the
following label. Take full care whenever servicing areas of the machine behind these covers.
This label is attached to all covers inside the machine where hazards from
laser light exist.

1.4 Safety of Toner
The machine’s toner is a non-toxic product consisting of plastic, iron, and small amounts
of dyes.
If your skin or clothes have come into contact with toner, try removing as much of it as
possible with dry paper tissues, and wash off with water. (Do not use warm water, as it
would turn the toner jelly-like and become fused with the fibers of the fabric.)
In addition, avoid bringing toner into contact with plastic material, as it tends to dissolve
easily.
Do not throw toner into fire to avoid explosion.

Part 2>Chapter 4>1.1 “Outline of Laser Exposure System”
The reader controller PCB serves to read image signals from the CCD and send image
signals to the main controller assembly. The video signals from the main controller assem-
bly are converted by the DC controller PCB into laser drive signals, and are turned into laser
intensity signals to suit signal levels by the laser driver PCB.
The laser intensity signals are used to cause the laser unit to generate a laser beam, which
is directed to the photosensitive drum for the formation of latent static images.

The edge of paper re-picked in double-sided mode is detected by the horizontal registra-
tion sensor to measure the displacement to the rear/front. Based on the measurement, the
timing of laser activation is changed with reference to the BD signal so that the image will
be placed at a specific position on the paper without fail.

3 Laser Driver Circuit
3.1 Controlling the Laser Unit
The laser driver circuit is used to drive the semiconductor laser according to the laser
drive signal from the DC controller PCB.
The laser driver circuit performs the following:
1. Turning on/off the laser.
2. Controlling the light intensity of the laser (APC control).
The signals have the following meanings and functions:
[1] Laser drive signal; used to drive the semiconductor laser.
[2] Sample laser activation signal; used to turn on the laser for intensity sampling (the result
is used for activation for imaging).
[3] Laser enable signal; goes ‘0’ when the laser is ready after the Start key is pressed.
[4] Image leading edge signal; used to start laser writing when paper reaches the image
leading edge sensor (PS12) mounted in front of the photosensitive drum.
[5] Used to monitor the laser intensity when the laser is turned on for sampling, and feeds
back the level appropriate to the intensity to the laser driver circuit.
[6] Used to control the output so that the feedback level and the reference level from the DC
controller will be identical.
[7] Laser intensity reference signal; used as the laser activation reference level determined
by the DC controller.
[8] Horizontal registration paper detection signal; used to adjust the image position by
changing the timing of laser activation with reference to the result of detection of the
edge of paper re-picked in double-sided mode by the horizontal registration sensor
(PS11).

2 Controlling the Primary Charging Roller Bias
2.1 Outline
Part 2>Chapter 5>4.4 “Controlling the Primary Charging Roller Bias”
The machine’s primary charging is a direct charging method that uses a charging roller. In
addition to a DC bias, the charging roller is subjected to an AC bias to ensure stable charg-
ing.
The following items relate to the control of primary charging:
[1] Turning on/off the bias.
[2] Controlling the DC bias to a specific level of voltage.
[3] Controlling the AC bias to a specific level of current.
[4] Controlling the photosensitive drum resistance detection mechanism (APVC control).
[5] Controlling the AC bias based on the readings of the environment sensor (humidity) and
the soft counters.
[6] Controlling the DC bias based on the reading of the drum sensor (temperature).

2.2 Turning On/Off the Bias
The primary charging roller bias is turned on/off as follows:
2.2.1 DC Bias
[1] When the primary charging output enable signal from the DC controller PCB goes ‘0’,
the DC bias output control signal (pulse signal) is generated.
[2] The DC bias is sent to the primary charging roller.
2.2.2 AC Bias
[1] When the primary charging output enable signal from the DC controller PCB goes ‘0’,
the AC bias output control signal is generated.
[2] The AC bias is generated to the primary charging roller.
2.3 Controlling the Current Voltage/Current to a Specific Level
The output level of the DC/AC bias applied to the primary charging roller is controlled by
the DC/AC bias output control signal from the PW-CPU.
2.3.1 Controlling the DC Bias to a Specific Level
[1] The output voltage level of the DC bias is fed back to the PW-CPU, and the DC bias
output control signal is varied as needed to suit the level when driving the transformer.
[2] The DC bias is made to assume a specific voltage level.
2.3.2 Controlling the AC Bias to a Specific Current Level
[1] The output current level of the AC bias is communicated to the drive control circuit and
is compared against the reference current level; the result is used to vary the AC bias
output control signal as needed to drive the transformer.
[2] The AC bias is made to assume a specific current level.

2.4 Temperature Correction of the DC Bias
When the temperature inside the machine increases, the resistance of the photosensitive
drum will decrease, thereby lowering the charging characteristics. To ensure a stable poten-
tial level, the drum sensor (U701) mounted to the rear side plate is used to check the tem-
perature inside the machine; when the temperature increases, the absolute value of the DC
bias level is increased.
F04-204-01
2.5 Humidity Correction of the AC Bias
The current level of the AC bias needs to be kept on the higher side to prevent uneven
charging because of a lower changing efficiency occurring in a low-humidity environment.
The AC bias, therefore, is varied as shown in F04-205-01 to suit the readings of the environ-
ment sensor (humidity). When the resistance of the drum surface decreases because of ad-
vancing wear, the current level is decreased to facilitate the flow of current.

2.6 Controlling the Detection of the Photosensitive Drum Re-
sistance (APVC control)
The primary charging efficiency changes because of changes in the site environment (tem-
perature, humidity), deterioration of the charging roller, and wear of the photosensitive
drum. A reference voltage is applied to the charging roller at time of last rotation every 500
prints (cumulative) or when the following service mode is executed:
COPIER>FUNCTION>DPC>D-GAMMA, and the level of output current at the time is
measured and corrected.
[1] When the main power switch is turned on, the reference voltage is applied to the charg-
ing roller, and the output is measured as the current level for use as feedback to the PW-
CPU.
[2] The photosensitive drum is charged (primary charging) using the voltage level deter-
mined by the PW-CPU.
If you have replaced the drum unit with a new one, be sure to execute the
following service mode: COPIER>FUNCTION>DPC>D-GAMMA.

3.2 Turning On/Off the Bias
The transfer charging roller bias is turned on/off as follows:
[1] When the transfer charging output enable signal from the DC controller PCB goes ‘0’,
the transfer bias output signal (serial communication) is generated.
[2] The transfer bias output control signal (pulse) is generated, and the DC bias is sent to
the transfer charging roller.
3.3 Controlling the Detection of the Transfer Charging Roller
Resistance (ATVC control)
The transfer charging efficiency changes because of changes in humidity and deteriora-
tion in the transfer charging roller. The reference current is applied to the transfer charging
roller during initial multiple rotation after the main power switch is turned on, and the re-
sulting output voltage is measured for correction.
[1] The reference current is applied to the transfer charging roller, and the output is checked
as a voltage level for use as feedback to the PW-CPU.
[2] The transfer charging mechanism operate using the voltage level determined by the PW-
CPU.
If you have replaced the transfer charging roller with a new one, be sure to
execute 'clean roller' in user mode ('adjust/clean').

3.4 Controlling the Output by Operating Mode
3.4.1 Types of Modes
The transfer charging output may be any of the following output modes, and the output is
varied to suit each mode. The switch-over among these is based on the combination of trans-
fer output mode signals from the DC controller PCB.
a. Image Transfer Bias
This bias is used to transfer toner from the photosensitive drum to paper, and is a positive
voltage.
b. Cleaning Bias
This bias is used to return toner sticking to the transfer charging roller to the photosensi-
tive drum, and applies a negative voltage.
• During initial rotation after the Start key is pressed
• During last rotation
• During initial rotation after jam removal or error resetting
• During execution of roller cleaning in user mode (‘adjust/clean’; in this case, the pri-
mary charging roller is also cleaned)
c. Reference Bias
It is an application voltage used for the transfer charging roller resistance detection con-
trol (ATVC control) mechanism. For every 1,000 prints (cumulative) or when 'roller clean' is
executed in user mode ('adjust/clean'), the voltage is applied at time of last rotation.
d. Sheet-to-Sheet Interval Bias
This bias is used in a non-image area (between sheets) in continuous print mode; the bias
level is reduced to prevent adhesion of toner to the transfer charging roller.
E064
Indicates the presence of a high-voltage (primary charging, transfer charg-
ing, development) output fault.

3.5 Controlling the Output
The output of the DC bias applied to the transfer charging roller is controlled as follows:

4.2 Turning On/Off the Bias
The separation static eliminator bias is turned on/off as follows:
[1] When the static eliminator bias enable signal from the DC controller PCB goes ‘0’, the
static eliminator bias output ON signal is generated.
[2] A DC bias is sent to the separation static eliminator.
4.3 Controlling the Bias to a Specific Voltage Level
The bias output is fed back to the output control circuit, thereby ensuring a specific level
of voltage.
4.4 Controlling the Output by Paper Type and Environment
Sensor (humidity)
In a low-humidity environment, separation can fail when thin paper is used or when the
second side of a double-sided sheet is hadled. To ensure good separation, the voltage ap-
plied is increased between -2.3 and -3.0 KV with reference to the type of paper and the
reading of the environment sensor (humidity).
The selection of an application voltage is done in response to the static eliminator bias
mode signal (serial communication) from the DC controller PCB.

The machine’s primary charging roller is cleaned by turning on the primary charging
roller cleaning solenoid (SL6) while the primary charging roller is rotating, thereby butting
the cleaning pad against the primary charging roller. At the same time, the cleaning pad is
moved back and forth in the axial direction of the primary charging roller.
Cleaning is executed under the following conditions:
• During last rotation after the cumulative count reaches 500 sheets
• During execution of roller cleaning in user mode (‘adjust/clean’; in this case, the clean-
ing bias is applied to the transfer charging roller pad for cleaning)

7.2.2 Controlling the DC Developing Bias
[1] When the DC bias ON signal from the DC controller PCB goes ‘0’, the bias control sig-
nals (pulse signals) are generated by the PW-CPU of the high-vole power supply PCB.
[2] The DC bias from the high-voltage main transformer is applied to the developing cylin-
der.
[3] The output voltage level of the DC bias is fed back to the PW-CPU.
[4] The pulse width of the DC control signal is varied to suit the return voltage, thereby
maintaining the DC bias to a specific level.
7.2.3 Controlling the AC Developing Bias
[1] When the AC bias ON signal and the AC pulse ON signal from the DC controller PCB
goes ‘0’, the AC transformer is driven.
[2] An AC bias is added to the DC bias and applied to the developing cylinder.
7.2.4 Controlling the Level of the DC Developing Bias
the level of the DC developing bias is varied between image area and non-image area to
prevent stray toner inside the machine.
In memory copy mode, the laser is driven based on binary image data which lacks density
information, not enabling adjustment using a density correction curve for the density of the
image being generated. To make up for the lack, the DC developing bias is varied for den-
sity adjustment.

7.3 Detecting the Level of Toner
A toner sensor (S1) of a piezoelectric oscillation type is mounted inside the developing
assembly for detection of the level of toner. The DC-CPU on the DC controller PCB reads
the output of the toner sensor as long as the developing clutch (CL3) remains on; it keeps
track of the ‘0’ state of the toner sensor (most recent two readings), and indicates the Add
Toner message as needed.

8.2 Monitoring the Waste Toner Case
The machine checks the waste toner case in reference to two levels.
The amount of waste toner inside the waste toner case is monitored by the waste toner
case full sensor (S2); the sensor is a pair of photosensors (light-emitting unit piece and
light-receiving piece). The machine will assume that the waste toner case has become full
when waste toner blocks the light between the two photosensors.
The DC controller PCB checks the waste toner case full sensor when the power is tuned
on and at time of delivery; it will assume a “waste toner full warning” after making a total of
100 prints after the waste toner case has become full, thereby indicating the Waste Toner
Case Full message on the control panel.
After the message Waste Toner Case Full is displayed in the control panel, the machine
will indicate 'E019' in its control panel if the case remains full upon generating about 2000
prints (cumulative).
If the waste toner case is not set, the light-blocking plate will block the light between the
photosensors, causing the Waste Toner Case Full message to appear.
Memo
The light between the photosensors is not visible to the eye.

3.2 Outline
The paper inside the cassette is held up by the lifter, and remains in contact with the
pickup roller when pickup takes place:
(1) The pickup motor (M2) is used to drive the pickup roller. The pickup roller is moved
down in relation to the feeding roller, and is brought into contact with paper only when
pickup takes place.
(2) The pickup roller is moved down when the cam released by the DOWN solenoid
(SL1) rotates by the drive of the main motor (M1).
The feeding roller and the separation roller serve to make sure that only one sheet of pa-
per from the pickup roller is sent to the feeding path; the No. 2 registration roller and the
vertical path roller then forwards the paper as far as the registration roller.
The drive for the vertical path roller and the No. 2 registration roller is provided by the
pickup motor (M2) through the vertical path clutch (CL1).
The registration roller is driven by the registration motor (M9).

3.4 Operation of the Cassette Lifter
The lifter is operated as necessary in the course of printing to maintain the stack of sheets
to a specific height.
3.4.1 Operation of the Lifter During Printing
The lifter is controlled by the movement of the pickup roller shaft. When the pickup roller
shaft pushes the lifter trigger lever, the cam is released, and the lifter starts to move up until
the lifter trigger lever stops the cam.
1) Each time the pickup roller DOWN so-
lenoid (SL1) goes ON, the pickup roller
shaft [2] moves down to initiate pickup
operation.
2) When the sheets [6] decrease and, as a
result, the descent distance [3] of the
pickup roller increases, the pickup roller
shift pushes down the lifter trigger lever
[4].
3) When the lever is pushed down, the cam
[5] is released, causing it to rotate.
4) The rotation of the cam turns the eccen-
tric cam [3] mounted to the same shaft.
The eccentric cam operates the lifter UP
lever [2] to move up the lifter gear [1].
5) The lifter moves up and, as a result, the
paper stack moves up; when the pickup
roller shaft reaches a specific height, the
lifter trigger lever is drawn back by the
work of a spring, thereby stopping the
cam. F05-304-01
The foregoing series of operation is repeated to maintain the height of the paper stack to a
specific level. The cassette pickup operation ends when paper runs out and the cassette pa-
per sensor detects the absence of paper.

CHAPTER 5 PICK-UP/FEEDING SYSTEM

3.4.2 Releasing the Lifter
The lifter is released mechanically when the cassette is slid out. When the machine is in
standby state, the lifter gear is held in place by the lifter gear retaining lever. When the cas-
sette is slid out, the lifter gear retaining lever is freed, thereby allowing the lifter to move
down.
If the main power is cut while the lifter is moving up, the lifter is held up
with the claw used to move up the lifter remaining in contact with the lifter
gear; the lifter will not be fully released in this condition, and damage can
occur if the cassette is forced out. Be sure to turn off and then on the main
power so that the machine will be in standby state whenever the cassette
must be slid out.

3.5 Cassette Pickup Operation
3.5.1 Rotating the Pickup Roller
The drive used to rotate the pickup roller is transmitted through gears. The cassette motor
rotates clockwise and counterclockwise to initiate pickup operation of the cassette 1/2.
3.5.2 Switching the Pickup Roller Drive
When the pickup roller rotates clockwise, the gear 1 moves up to drive the pickup roller
of the upper cassette holder; when the motor rotates counterclockwise, on the other hand,
the gear 1 moves down to drive the pickup roller of the lower cassette holder. The figure be-
low shows how the drive of the pickup roller is controlled.
3.5.3 Pickup Roller Shaft Reference
The up and down movement of the pickup roller when the cassette is set in the machine is
driven with reference to the position of the pickup roller shaft.

The pickup roller and the feeding roller are supported by a roller holder, and the pickup
roller is moved up and down in relation to the feeding roller. In standby state, the pickup
roller is at the uppermost position; during pickup operation, on the other hand, it moves
down to reach the paper surface. It operates as follows to pick up a single sheet of paper:
1) When the pickup solenoid (SL1) goes ON, the drive of the main motor (M1) causes the
cam 1 to rotate.
2) The rotation of the cam 1 causes the pickup lever to swing.
3) The swing of the lever causes the pickup roller to move down to come into contact with
the paper, and the pickup motor (M2) starts pickup operation.
4) The rotation of the cam 1 moves up the pickup roller shaft.

When a delay is detected by a pickup sensor because of wear on the pick roller, pickup
retry operation is executed. If a delay is still detected after a retry, the control panel indicates
the Jam message.
3.7.1 Conditions for Detecting a Delay
Paper does not reach the retry sensor when it has been moved over a specific distance af-
ter the pickup DOWN solenoid (SL1) has gone ON.

3.7.2 Paper Retraction
If a delay is detected once again after a retry and the jam must be removed, the paper can
become torn if an attempt is made form the cassette side. To enable removal from the right
cover side, the following operation takes plate:
1) After detecting the jam, the retracting roller is driven for a period equivalent to a dis-
tance over which paper may be moved 10 cm. The paper will be moved to a point where
it is in view when the right cover is opened.
2) The control panel indicates an instruction to the effect that the jam may be removed
from the right cover side.
3) The right cover may be opened to remove the jam. If the jam is not in view when the
right cover is opened, it may be removed from the cassette side.

2) Moving Up the Lifter
When the main power is turned on with the cassette set in the machine or the cassette is
slid in while the machine is in standby state, the pickup roller shaft moves down to push
down the lifter trigger lever.
The cam is released when the pickup roller shaft pushes one side of the lifter trigger lever,
and the drive from the main motor (M1) move sup the lifter.
When the pickup roller remaining in contact with the paper surface moves up to a specific
height, the movement of the levers cause the pickup roller shaft to return to the uppermost
position to end the upward movement of the lifter.

7.3.2 Operation
1) Timing of Detecting Home Position
When the main power switch is turned on, During jam recovery, When the front cover is

2) Start Position
The detection start position is set at a point about 10 mm from the edge of paper whose
movement is ideal with reference to the data on the paper width collected from the slide
guide on the manual feed tray and the cassette size when the registration sensor goes ON.
3) Detectiong operation
When paper fed to the duplex feeding assembly reaches the registration roller, the hori-
zontal registration motor (M3) goes ON, and the duplex horizontal registration sensor
(PS11) starts paper edge detection. The detection takes place for each time a double-sided
print is made.
The detection of paper position is done with reference to the start position, and the dis-
placement from the actual paper position is identified with reference to the drive pulses from
the motor (1 pulse = about 0.16 mm).

9 Disassembly and Assembly
The discussions that follow cover the machine’s mechanical characteristics and how to
disassemble/assemble the machine. Keep the following in mind whenever you work with the
machine:
1. The power plug must remain disconnected for safety when disassembling/assembling
the machine.
2. Unless otherwise noted, the machine may be assembled by reversing the steps used to
disassemble it.
3. The screws must be identified by type (length, diameter) and location.
4. The mounting screws used for the grounding wire and the varistors come with a washer,
which must not be left out when assembling the machine.
5. As a rule, the machine must not be operated with any of its parts removed.
6. The door switch or the main power switch must be turned off whenever the duplex unit
or the fixing/feeding unit must be slid out.
7. The toner must not be disposed of into fire to avid explosion.
8. Do not operate the machine without locking the feeding assembly in place to avoid dam-
age.

The fixing motor (M4) is faulty. The fixing film sensor (P26) is faulty.
If a code from E000 through E003 is indicated, the indication will not be
reset even when the main power switch is turned off and then on, requiring
clearing of the error in service mode
(COPIER>FUNCTION>CLEAR>ERR).
If E001 or E003 is detected within 3sec after the front cover switch is iden-
tified as being open/closed, however, the error indication will be reset when
the main power switch is turned off and then on. This is to prevent the user
from placing a service call in response to an error detected while the switch
operation is not stable (as occurring immediately after the switch is turned
on/off).

4 Disassembly and Assembly
The discussions that follow cover the machine’s mechanical characteristics and how to
disassemble/assemble the machine. Keep the following in mind whenever you work with the
machine:
1. The power plug must remain disconnected for safety when disassembling/assembling
the machine.
2. Unless otherwise noted, the machine may be assembled by reversing the steps used to
disassemble it.
3. The screws must be identified by type (length, diameter) and location.
4. The mounting screws used for the grounding wire and the varistors come with a washer,
which must not be left out when assembling the machine.
5. As a rule, the machine must not be operated with any of its parts removed.
6. The door switch or the main power switch must be turned off whenever the duplex
unit or the fixing/feeding unit must be slid out.

3.5 Protective Functions
The machine’s each power supply PCB is equipped with an overcurrent protection circuit
designed to cut off the output of each power supply when they go ON.
While the signals RMT1 and RMT2 from the main controller PCB are used to turn on the
output of each power supply PCB, if 3VB stops from the composite power supply PCB be-
cause of a fault in the high-violate output or melting of the fuse, all outputs of power will be
cut.

CHAPTER 8 PAPER DECK-L1
8-1 P
1.1 Pickup
1.1.1 Outline
The paper deck (hereafter, “deck”) is capable of accommodating as many as 2500 sheets
(A4/LTR, B5; 80 g/m2 paper) at a time, and is designed to operate in response to control
signals from the DC controller of its host machine.
The lifter of the deck is driven by the deck lifter motor (M2D), and paper is picked up and
moved by the drive of the deck main motor (M1D).
1.1.2 Pickup Operation
The paper placed inside the deck is held up by the lifter, and is kept in a specific pickup
position.
When the Start key is pressed and the deck pickup clutch (CL2D) goes ON, the drive of
the deck main motor (M1D) rotates the pickup roller to pick up paper; at this time, the
pickup/feeding roller and the separation roller serve to make sure that only one sheet of pa-
per is moved forward. When the deck pickup sensor (PS1D) detects paper thereafter, the
deck pickup roller releasing solenoid (SL1D) goes ON so that the pickup roller leaves the
stack of paper.
The deck feeding roller starts to rotate when the deck feeding clutch (CL1D) goes ON.
The picked paper is moved to the registration roller of the host machine, and is made to arch
for removal of the slack.
The registration roller is controlled so that the leading edge of paper will match the image
on the photosensitive drum.

1.2 Detecting Paper in the Deck
1.2.1 Detecting the Presence/Absence of Paper
The presence/absence of paper inside the deck is detected by the deck paper absence sen-
sor [1] (PS2D). When the paper [3] placed on the lifter [2] runs out and, as a result, the pa-
per detecting lever [4] of the pickup roller assembly leaves the deck paper absent sensor, the
control panel of the host machine will indicate the absence of paper.

1.2.3 Detecting the Level of Paper in the Deck
The deck uses the deck paper supply position sensor (PS8D), deck paper level sensor
(PS7D), and deck paper absent sensor (PS2D) to find out how much paper remains inside its
compartment and to indicate an approximate level in the control panel of the host machine
as shown in the following table (indicating combinations of paper levels and sensor states):
Paper level PS2D PS8D PS7D Indication in

CHAPTER 8 PAPER DECK-L1
8-6 P
1.3 Deck Lifter
1.3.1 Detecting the Presence/Absence of Paper
The lifter of the deck is connected to a reel by means of a cable, and is driven by the deck
lifter motor (M2D), whose direction of rotation changes the direction (up/down) of the
movement of the lifter.
When the compartment is slid inside the deck, the deck open detecting switch (SW1D) is
pushed; the deck then starts to move up when the deck open sensor (PS9D) detects the light-
blocking plate. It will stop to move up when the deck lifter position sensor (PS4D) detects
the top face of the stack of paper placed on it.
If, for some reason, the lifter fails to stop moving up after the sensor lever blocks the deck
lifter position sensor, the deck lifter upper limit sensor (PS3D) will go ON to stop it and
thereby to prevent image.
When the deck open switch (SW100D) is pushed, on the other hand, the lifter starts to
move down, and continues to move down until it leaves the sensor lever of the deck paper
supply position sensor (PS8D; falling edge of the sensor output).
When supplied, the paper pushes the lever of the deck paper supply position sensors, and
the lifter will move farther down until the stack of paper leaves the sensor lever.
Each time paper is supplied, the lifter repeats its descent movement until the deck lifter
lower limit detecting switch (SW2D) is pushed (point of maximum paper supply).

1.3.2 Indicating the Level of Paper (deck front cover)
The drive of the deck lifter motor [1] (M2D) is received by a coupling [2], and is for-
warded to the rack [4] by way of the drive belt [3]. The rack is equipped with a black belt
[4] designed to move inside the window [7] in the deck front cover [6] in keeping with the
movement of the rack.
When the paper starts to run out and the lifter moves up to the pickup position as a result,
the area of the black belt in the window accordingly increases (while the white area de-
creases), indicating the increasing level of paper.

1.4 Opening/Closing of the Compartment
1.4.1 Opening/Closing of the Compartment
When the deck open switch (SW100D) is pushed, the deck open solenoid (SL2D) goes
ON, and the compartment is released; as a result, the compartment is pushed several centi-
meters forward. At the same time, the deck lifter motor (M2D) starts to rotate, and the lifter
inside the compartment moves down.
When the compartment is pushed inside the deck by hand, the deck open sensor (PS9D)
will detect the light-blocking plate of the compartment, and the lifter will move up to the
pickup position.
When the deck lifter motor starts to rotate, the deck open indicator (LED100D) on the
open switch PCB will go ON or start to flash.

1.5.2 Controlling the Deck Lifter Motor (M2D)
The deck lifter motor control circuit is found on the side deck driver PCB. F08-105-02 is
a block diagram of the PCB.
The combination circuit found in the figure consists of various logic circuits, and a spe-
cific combination is used to rotate the deck lifter motor clockwise or counterclockwise: out-
put signals from sensors and deck lifter motor drive command and deck lifter ascent com-
mand from the DC controller of the host machine.
If the deck lifter position sensor (PS4D) does not detect the lifter within a specific period
of time in spite of the presence of the deck lifter UP signal, an alarm (code: 05) will be indi-
cated in service mode: DISPLAY>ALARM1>BODY.

grammed in the DC controller of the host machine. When the DC controller of the host ma-
chine identifies a jam, the machine will deliver the sheets that are ahead of the jam, and will
stop the operation; thereafter, the host machine will indicate instructions for jam removal in
its control panel.

3 Disassembly and Assembly
The discussions that follow cover the machine’s mechanical characteristics and how to
disassemble/assemble the machine. Keep the following in mind whenever you work with the
machine:
1. The power plug must remain disconnected for safety when disassembling/assembling
the machine.
2. Unless otherwise noted, the machine may be assembled by reversing the steps used to
disassemble it.
3. The screws must be identified by type (length, diameter) and location.
4. The mounting screws used for the grounding wire and the varistors come with a washer,
which must not be left out when assembling the machine.
5. As a rule, the machine must not be operated with any of its parts removed.

form the following two tasks:
Adjusting the Paper Level Indicator
1) Move the drive belt [2] of the paper
level indicator behind the front cover
[1] by hand so that the white area inside
the window [3] increases, i.e., in the di-
rection for the arrow [4]; move it until a

The urethane sponge used on
the deck separation roller is
pink upon foaming, and
changes over time to orange and
then yellow, accelerating the
rate of change if exposed to
light.
This is a general characteristic
of urethane sponge, and does
not affect its performance. (The
part is not offered in different
colors.)
3.4.7 Adjusting the Deck Separation Roller Pressure
If double feeding or pickup failure occurs
when the deck is used as the source of pa-
per, move the position of the pressure
spring [2] of the deck separation roller [1].
• If pickup failure occurs, move the
spring in the direction of arrow A.
• If double feeding occurs, move the
spring in the direction of arrow B.

3 Disassembly and Assembly
The discussions that follow cover the machine’s mechanical characteristics and how to
disassemble/assemble the machine. Keep the following in mind whenever you work with the
machine:
1. The power plug must remain disconnected for safety when disassembling/assembling
the machine.
2. Unless otherwise noted, the machine may be assembled by reversing the steps used to
disassemble it.
3. The screws must be identified by type (length, diameter) and location.
4. The mounting screws used for the grounding wire and the varistors come with a washer,
which must not be left out when assembling the machine.
5. As a rule, the machine must not be operated with any of its parts removed.

5 Making Adjustments
5.1 Outline
If you want to use envelopes with a different configuration in the envelope feeder, you
need to replace the spring to suit the new envelope.
The spring may be painted either green or red; one is already fitted, and the other is ex-
pected to be stored by the user near the host machine.
Be sure to check that the correct spring is fitted whenever you want to switch to envelopes
of a different configuration.
5.1.1 Envelopes and Type of Spring
• Use the green-painted spring for COM10, Monarch, DL, and YOUKEI 4.
• Use the red-painted spring for C5 and B5.
5.2 Replacing the Spring
5.2.1 Replacing the Spring
1) Remove the two mounting screws [1]
each, and detach the side guide plate [2]
(front, rear) and the lifter [3].
F11-502-01
2) Holding the bottom (1st, 2nd loops) of
the spring [1], turn it clockwise to free
it from the envelope feeder.

CHAPTER 11 ENVELOPE FEEDER ATTACHMENT-B1
11-8 P
3) Thread the edge of the spring [1] that
comes as an attachment so as to fit it
through the catch 1 [2] and then the
catch 2 [3].
4) Holding the bottom (1st and 2nd loops)
of the spring, fit it through the catch 3
[4]; then, thread it until distance A is
about 15 mm from the catch 2 [3].
At this time, check to make sure that the
spring is firmly on the bottom plate.
F11-502-03
5.3 Changing the Size
5.3.1 Changing the Size
1) Match the lifter [1] and the side guide
plate [2] against the size positioning
line of the envelope feeder in relation to
the edges of the side guide plate; then,
secure them in place by using two
mounting screws [3] each.
F11-503-01
Take care so that the side guide
plate will not extend beyond the
envelope feeder (as by choosing
the wrong mounting hole). See
the next page for the correct
mounting hole.

If any such problem is noted, adjust the
height of the side member as follows;
otherwise, these steps need not be per-
formed:
5.9.2 Making Adjustments
1) Connect the machine to the host ma-
chine.
2) Take out the paper from the deck.
3) Remove the right cover of the machine.
4) Loosen the two fixing screws [2] of the
side member [1].
5) With the side member in contact with
the floor, tighten the fixing screws. At
this time, refer to the index so that the
left and right screws match against the
same index.

6) Disconnect the machine from the host
machine, and then connect it once
again. If it can be done without extra
force, mount the right cover for the ma-
chine, and put the paper back into the
deck. If extra force is needed, go to the
next step.
7) Check the index of the side member.
8) Loosen the fixing screws of the side
member.
9) While referring to the index, raise the
side member 1 mm, and then tighten the
fixing screws.

1 Making Initial Checks
1.1 Checking the Site of Installation
1. There must be a source of power rated as indicated (rated voltage ± 10%). The source
must be exclusively of the machine, and the power plug must remain connected through-
out the night.
2. The machine must not be in a high-temperature/-humidity area (near a water faucet, wa-
ter boiler, humidifier), must not be cold or subject to dust. There must not be a source of
fire nearby.
3. The machine must not be subjected to ammonium gas.
4. The machine must not be subjected to the direct rays of the sun; as necessary, curtains
must be provided.
5. The room must be well ventilated.
6. The floor must be flat to keep the machine level.
7. The source of power must provide power night and day.
Check the sight against the above requirements.
1.2 Checking the Originals
Check to find out if the symptom is caused by the originals used or by the machine:
1. The copy density is optimum if set to index 5 ± 1.
2. Originals with a reddish tone tend to prevent reproduction of good contrast.
3. Originals of specific densities can produce copies that can be mistaken as faulty.
Memo
• An original with a reddish tint can produce copies with poor contrast.
• Diazo copies used as originals or originals with a high degree of trans-
parency can produce copies that can be mistaken as “light copies.”
• Originals prepared in pencil or with a greenish tint can produce copies
that can be mistaken as “light copies.”
1.3 Checking the ADF Platen, Copyboard cover, and
Copyboard glass (standard white plate)
If the ADF platen, copyboard cover, or copyboard glass is soiled, clean it with a solution
of mild detergent; if scratched, replace it.

1.4 Charging Roller and Static Eliminator
1. Check the transfer charging roller and the separation static eliminator for dirt and a fault
(damage).
2. Check to make sure that the transfer charging roller and the separation static eliminator
are correctly mounted.
1.5 Checking the Developing Assembly
1. Check to make sure that the members on both ends of the drum are in contact. Other-
wise, light images can result.
2. Check to see the surface of the developing cylinder is coated with an even layer of toner.
Otherwise, light images or uneven density can result.
1.6 Checking the Paper
1. Check to see if the paper used is of a recommended type. Advise the user that paper not
of a recommended type may fail to bring about expected results.
2. Check to see if the paper is moist. Moist paper can adversely affect transfer, causing
poor images or separation faults (leading to jams and wrinkles). Advise the user on the
correct method of storing paper.
1.7 Checking the Periodically Replaced Parts
Check with the scheduled servicing chart and the table of periodically replaced parts. Re-
place parts that have reached the ends of their lives.
1.8 Image Adjustment Basic Procedure
If the copies have uneven density (difference between front and rear), light images, or
foggy background, try the Image Adjustment Basic Procedure first to see if the problem is
corrected.

1.9 Others
In winter, bringing a machine from a cold to warm place can cause condensation inside
the machine, causing various problems.
Memo
1. Condensation in the optical system (glass, mirror, lens) can cause dark
images.
2. Condensation in the charging system can cause leakage.
3. Condensation on the pickup/feeding guide can cause feeding faults.
If condensation is noted, dry wipe the part, or leave the machine pow-
ered and alone for 60 min.

6.1.2 Checking the Photointerrupters
The photointerrupters are checked in service mode; go through the tables attached to the
lists of electrical components to find out the state* of a specific sensor, which may be any of
the following:
a. Paper Sensor
Move the sensor lever by hand to simulate the presence of paper; then, check the Service
Mode screen.
If it is difficult to check the Service Mode screen while moving the sensor lever, put paper
over the point of detection, and then check the Service Mode screen.
b. Open/Closed Sensor
Check the Service Mode screen while opening/closing the cover/unit in question.
c. Position Sensor, Presence/Absence Sensor
Move the unit in question by hand. Try removing and then mounting it. If the I/O level
changes in response to operation, the sensor may be assumed to be normal.
To check a photointerrupter found inside a unit which is detached in con-
junction with a drawer connector, be sure to check the Service Mode while
the unit in question is set.
*The state of a sensor refers to any of the following:
• For a paper sensor, the presence or the absence of paper.
• For an open/closed sensor, the state in which the cover/unit is closed.
• For a home position sensor or a set sensor, the item in question is in home position or
set in place.

6.7 Variable Resistors (VR), Light-Emitting Diodes, and Check
Pins by PCB
Of the variable resistors, light-emitting diodes, and switches used in the machine, those
needed for service work in the field are discussed:
1. Some LEDs emit dim light when they are off because of leakage cur-
rent; this is a normal condition, and must be kept in mind.
2. VRs that may be used in the field:
VRs that must not be used in the field:
Do not touch those VRs and check pins not discussed herein; they are for
exclusive use in the factory, and require high accuracy and special instru-
ments.

6.7.1 Main Controller PCB
F04-607-01
The DIP switch (SW1002) is designed for adjustments at the factory, and is not normally
used in the field.
<When Replacing the PCB>
a. Transfer the following from the old to new PCB:
• shorting connector of J1060
• BOOT ROM of J1010
• SDRAM
• counter memory PCB
b. Protect the back-up data as follows:
1) Back up all data using the Service Support Tool.
2) Replace the main controller.
3) While holding down the keys ‘2’ and ‘8’ of the control panel, turn on the main power (to
start download mode). You will not be able to perform the following if you start up in
the usual way, since the Box text file data and control data on the hard disk will be ini-
tialized.
4) Download all data using the Service Support Tool.

1 Upgrading
1.1 Outline
The machine is upgraded either by downloading data from a PC or by replacing its
DIMM/ROM.
The following five items are upgraded by downloading from a PC:
• BOOT ROM (machine J1009 DIMM ROM)
• HD Format (machine HDD; formatting)
• Language (machine HDD)
• RUI (machine HDD)
• System (machine HDD)
• DADF-H1 (CPU; Use the downloader PCB) See 1.6 Downloader PCB
• Finisher-J1 (CPU; Use the downloader PCB) See 1.6 Downloader PCB
As indicated, the language module may also be downloaded.
The machine may be connected to a network when downloading data from a PC.
For instructions on upgrading by means of replacing the DIMM/ROM, see 1.7 “Upgrad-
ing by Replacing the DIMM/ROM.”
1.1.1 Download Mode
The machine provides two types of download modes; although any of the two may be
used to download all files, select with care if you want to format the hard disk (select the
HD Format), as a specific partition must be selected.
You can use any of the two when using a parallel cable; however, the use of a network
cable will require you to start up the machine’s network environment, necessitating the use
of downloading in service mode.
• Downloading in Download Mode
To start download mode,
1) While holding down ‘2’ and ‘8’ on the keypad at the same time, turn on the power
switch.
2) Hold down ‘2’ and ‘8’ on the keypad until the bottom of the touch panel indicates the
message “Download Mode.”

If you use the Service Support Tool while the machine is not in download
mode, the machine will treat data from the interface as a local print job and,
accordingly, will increment the job count.
When you use the Service Support Tool, be sure to switch the machine to
download mode in advance by following the instructions on the screen.
1.1.2 Making Pre-Checks
Prepare the following:
• PC to which the Service Support Tool (version 1.25 or later) has been installed
• System CD (for iR2200/iR2800/iR3300)
• Connection cable
The type of cable depends on how the machine is to be connected to the PC.
• In the case of a bi-Centronics interface,
obtain a parallel cable (indicating IEEE 1284Std-compliant).
• Using a Network Cable
Connect the machine with the PC using a cross Ethernet cable or a straight Ethernet
cable and a HUB.
The following shows how a cross Ethernet cable may be used.

Memo
Differences in Connection Between Bi-Centronics Cable and Network
Cable
Each has its own advantages and disadvantages; select one to suit specific
needs:
Connection with a Bi-Centronics Cable (using a parallel cable)
Advantages:
• You can use the Service Support Tool without considering the environ-
ment of the user’s network.
• If the system is not installed on the hard disk, the system may be installed
or the hard disk may be formatted using download mode.
Disadvantages:
• The specifications of the PC used or the chip set may not allow the use of
high-speed mode, i.e., it has a low level of compatibility.
• The PC must have a parallel interface.
• You can not use high-speed mode on Windows NT or Windows 2000.
Connection with a Network Cable
Advantages:
• It is relatively high speed.
• It is less dependent on the PC to be used.
• The use of a cross cable enables direct connection.
Disadvantages:
• You must change the network settings of the machine or the PC to suit the
user’s network environment. More importantly, you must change the ma-
chine back to its initial settings after the task.
• You must have a good knowledge of networking.
• The system must start up normally and the network settings must be cor-
rect.
Memo
Points to Note When Using a Bi-Centronics Interface and a Network
The Service Support Tool allows you to select one of two interfaces to suit
specific needs. If both are in use, you must turn the machine off and then on
first before making a switch-over (i.e., from Bi-Centronics to Network or
vice versa), thereby preventing errors in the event of simultaneous writing
operations.

Memo
About the Language Module (Language)
A language module is a unit containing the language data needed to indi-
cate messages in the control panel, each module designed for a specific lan-
guage. Install only those language modules you need, thus saving time
spent for downloading. You can switch among installed language modules
in user mode: common settings> display language. At time of shipment,
five modules (languages) are installed. The modules will be lost once you
format the had disk, requiring you to install them once again to suit the
needs of the user. To check the version of the modules, make the following
selections: COPIER>DISPLAY>VERSION>LANG-XX. Check to make
sure that the version of each language module matches the version of the
installed system software; otherwise, use the langue module built into the
system software to start up. The built-in module is not part of the modules
that may be selected as the display language; for this reason, you will not
be able to make use of the language switch unless you have installed mod-
ules independently of the system software. If you replace an existing lan-
guage module with a module of an inappropriate version, ‘E744-0001’ will
be indicated when the machine is started up for the first time; to reset the
error, install a module of the correct version.

2) Turn off the machine’s main power switch, and disconnect the power plug and the net-
work cable.
Memo
Limits on Preparing the BOOT ROM
You will not be able to prepare the BOOT ROM unless the following condi-
tions are met:
On this screen, it is in the case of iR8500.
• The model of the machine is the same; e.g., you cannot use the iR2200
BOOT ROM data to upgrade an iR5000.
• The parameter “function” (COPY or PRINTER) must match when down-
loading the system software; i.e., you cannot use the iR2200N (PS/PCL
model) BOOT ROM data to upgrade an iR2200. (The same is true of
from PS/PCL model to COPY.)
Any attempt made in disregard of the above will cause a mismatch error
when the machine runs a check before writing.
