2.8 Print Speeds with Various Settings
Print speed is up to 30 ppm for A4 size and 32ppm for Letter size when loading A4 or Letter
size paper from the paper tray in the plain paper mode.
Actual print speed varies depending on the media type or paper size as shown in the tables
below;
<A4/Letter size>
Media type setting
Plain paper, Recycled paper 30/32 ppm
Plain paper thin 30/32 ppm
Thick paper, Envelope, Envelope thin, Label 15/16 ppm
Thicker paper, Bond paper, Envelope thick 3 ppm
Print speed
(for all models)
<Smaller size than A4 or Letter>
Media type setting
Plain paper, Recycled paper 0 to 90 second 32 ppm,
90 second or later 15 ppm
Plain paper thin 30/32 ppm
Thick paper, Envelopes, Envelopes thick,
Label, HAGAKI
Thicker paper, Bond paper, Envelopes thick 3 ppm
0 to 9 second 16 ppm,
9 second or later 15 ppm
Print speed
(for all models)
Note :
• The print speed may vary according to conditions, such as paper size and paper
tray.
• When a smaller size paper than A4 or Letter is printed, the temperature on both
edges of the fuser unit is much higher than the temperature on the center of the unit
where the paper is fed depending on the setting or model. Therefore, the print
speed is slowed in order to decrease the temperature on the edges after the
specified time, it is maximum print speed when you first start printing.
• The actual print speed varies depending on the paper size.

3.2.1 Scanner unit
The scanner unit is equipment which scans the paper using the CCD unit. This machine
prints the scanning data (copy) or data is sent by fax (fax transmission).
There are two kinds of scanning method of the scanner unit. One is operation to scan with
the scanner unit, the paper is placed on the document glass, the CCD unit moves is the
bottom of it, and it scans the paper, and other is operation to scan in connection with the ADF
unit, scan the paper which has been sent over the immovable CCD unit.
1. CCD unit
The CCD unit includes the charge coupled device (CCD) sensor (Resolution of horizontal
scanning: Max 600dpi, color scanning). The cold cathode fluorescent lamp lights the
document, and the reflection from the scanned image data is transferred to the lens by
the mirror. The lens reduces the scanned data so that the image is generated on the
CCD.
2. Driving of the CCD unit
The CCD unit is supported by the CCD rail and assembled on the CCD drive belt. When
the CCD motor is rotated clockwise, the CCD unit on the CCD drive belt scans the
document while sliding to the right hand side. In this case, the CCD unit has the capacity
to scan at 2,400dpi resolution of sub scanning .
3. CCD unit home position detected (FB home position detected)
The CCD unit is configured at the FB home position to determine the scanning position of
the sub scanning direction. Based on the home position, the position performing the
white level compensation or the scan lock other than the scanning position is configured.
The FB home position is detected when the CCD unit intercepts the home position
sensor in the left side of the inside of the scanner unit.
4. White level compensation
Whenever the variation of the CCD unit by CCD unit, the correction of the time
degradation and the value of the while color scans, in order to make them not different.
The white level compensation keeps a fixed value of the white color by scanning the
white-level reference film inside the scanner unit with the CCD.
5. Function of scanner lock lever
The CCD unit is fixed so that the CCD unit moves and may not be damaged when
product transfer.

6. Scanning operation (The CCD unit moves under the immovable document.)
Open the document cover, place a sheet of the document (or opened book) onto the
document glass, and close the document cover. Then, the machine starts scanning by
the operation of the panel, and the CCD drive mechanism is started and the scanning
operation is started.
The CCD motor is rotated so that its action is transferred to the CCD drive belt through
the gear train.
The CCD unit scans the document while sliding to the right hand side.

3.2.2 ADF unit
The ADF unit is equipment which sends one document or the document for every plurality to
the ADF scanning part of the scanner unit, and performs continuation scanning. As for the
ADF of this machine, the duplex scanning is also possible.
Performance of the ADF
- The number of maximum capacity: Up to 50 sheets
- Maximum resolution: Up to 600dpi
- Maximum scanning speed:
- Maximum input media size: Width 148.0mm, Length 148.0mm
- Minimum input media size: Width 215.9mm, Length 355.6mm
1. Function of each roller
- Pick-up roller
Send the document of the inserted ADF to the inside of the ADF.
- Separation roller
Separate the sent document one by one.
- Paper feed roller 1, 2, 3, 4
Send the document.
- SB (switch back) roller ASSY
When the duplex scanning, this motor is rotated by contraries, draws the sent out
document to the inside of ADF again.
- Eject roller
Eject the document.
32 pages/minute (Letter size) (Simplex scanning)
14 sides/minute (Letter size) (7pages/minute) (Duplex scanning)
2. Function of each sensor
- Document front sensor 1
Detects whether the document is set in the ADF.
- Document front sensor 2
Detects whether the document is sent by the separation roller.
- Document rear sensor
Detect the timing of the scanning start of the document.
- Switch back sensor
When the duplex scanning, detect the timing of the reversing of the SB roller by the
document passed.
- Document cover open sensor
Detects whether the document cover is opened or not. Even if the document is set into
the ADF, the machine starts scanning the document glass ignoring the ADF.
3. Function of each motor/solenoid
-ADF motor
Driving source of overall ADF.
- Paper feed solenoid
The paper feed solenoid stops the driving of the pick-up roller and separation roller
while the document is drawn in order to prevent that the next document is drawn into
the ADF while duplex printing.
- Switch back solenoid
Switches the direction of rotation of the SB roller ASSY.

5. ADF simplex scanning (The document moves over the immovable CCD unit.)
(1) Set the document face up into the document chute. When the machine starts
simplex scanning, the ADF motor is rotated clockwise, the pick-up roller draws the
document, and the separation roller and separation pad send a sheet of the
document to the ADF one by one from the top page of the stacked documents.
(2) The document is passed through the paper feed rollers 1, 2 and 3, and is passed
over the CCD unit so that the document is scanned. Then, the document is ejected
to the document cover LGL by the eject roller.

3.3.1 Plate-up Function of the Paper Tray
The plate ASSY in the paper tray is pushed up with the motor drive and not with the spring in
order to maintain the constant pressure to the feed roller and to give the paper feeding
performance.
When the paper tray (Tray1 cassette) is installed into the printer, the lift gear 46 is rotated,
and the motor drive is transmitted to the plate ASSY so that it is pushed up.

3.3.3 Paper registration
After the paper top position is detected by the regist actuator front, the paper, separated into
individual sheets by the separation roller, is fed further for a specified time, and the paper top
position reaches the regist roller so that the paper skew is adjusted. Then, the regist
solenoid is turned on, the regist roller starts turning, and the paper is fed to the transfer roller
in the drum/toner ASSY.

3.3.4 Paper eject
After the printing image on the exposure drum is transferred onto the paper, the paper is fed
to the fuser unit to fix unfixed toner onto the paper by the heat roller and the pressure roller in
the fuser unit.
Afterwards, the paper is ejected from the fuser unit. The paper eject actuator detects
whether the paper is ejected correctly or not.
After the paper exits from the heat roller, the paper is turned by the back cover and ejected
face down into the top output tray through the eject roller.

3.3.6 Paper feeding from the MP tray
The separation roller MP is connected with the feed roller through the gear in the MP roller
holder ASSY. When the separation roller is driven, therefore, the feed roller is also driven. At
this time, the recording paper is drawn out of the MP tray by rotation of the paper feed roller
MP contacted with the recording paper. The drawn recording paper is separated into
individual sheets by the separation roller MP.

3.4 Toner Cartridge
3.4.1 Methods for Detecting Toner Life
When the machine detects the toner life end, "Replace Toner" is displayed. The toner life is
displayed through the following two ways. First, such indication is displayed when detection
is performed by the toner sensor; second, it is displayed at the time when a rotation rate of
the develop roller reaches its upper limit.
(1) Detection by the toner sensor
The low amount of toner remaining can be detected by checking the imperviousness to
light of the toner in the cartridge by means of the transmissive photosensor.
(2) Detection by means of rotation rates of the develop roller reached its upper limit
The machine counts the accumulated number of the develop roller.

Confidential
3.4.2 Cartridge life
A new toner cartridge can print approximately 3,000 (standard toner) or approximately 8,000
(high yield toner) A4 or Letter size single-sided pages at normal duty (ISO/IEC19752). In the
case of low-duty printing, if the number of printed pages are reached the cartridge life,
"Replace Toner" message appears on the LCD before the toner runs out because the
developer roller surface or other toner sealing is worn out due to a rotation of the rollers.

Memo :
• If reached the cartridge life end, "Replace Toner" message appears even if the

<Cartridge Life>
As the deterioration of toner will be less in case of printing more pages continually once time
than usual, the more printing pages per job, the more printable pages of toner cartridge.

Increasing the number of times of power switch ON and warming operation in company with
opening or closing cover will also cause the deterioration of toner, so the more frequency
those operations be taken, the less pages the toner cartridge can print.

3.4.3 New toner detection
(1) The main motor will drive gear (4) through the interconnection of other gears.
(2) When gear (4) is rotated, rib A on that gear will push against the new toner actuator; the
new toner sensor will detect the actuator motion, and the toner sensor detects that a
new toner cartridge has been installed.
(3) The standard toner cartridge has Rib A and Rib B on gear (4).
When the toner actuator is pushed twice, the two signals that are generated by the new
toner sensor, tell the machine that a standard toner cartridge has been installed.
(4) The high yield toner cartridge only has Rib A on gear (4).
When the toner actuator is pushed once, the signal that is generated by the new toner
sensor, tell the machine that a high yield toner cartridge has been installed.

When the new toner detection switch detects that the toner cartridge is replaced with a new
one, the developing bias voltage is initialized at the same time.
The toner used for the printer has a property that print density is light first and gradually
darker in the course of usage. The developing bias controls the toner property so that the
print density is constant from first to last.

To obtain a print result of a constant density all the time, the printer counts the number of print
pages immediately after the toner cartridge is replaced and changes the bias voltage
according to the accumulated number of prints with the toner cartridge.
The bias voltage is changed with the steps described below:
(1) When the new toner sensor detects that the toner cartridge is replaced with a new (full)
one, the developing bias is set to 400V (initialized).
(2) After that, the bias voltage is stepped down according to the number of prints. Ultimately,
the bias voltage is 300V.

3.5 Print
3.5.1 Basic Principle
The printing process consists broadly of 5 processes: electrification, exposure, development,
transfer and fusing.
1. Charging: The surface of an exposure drum is electrically charged.
2. Exposure: A printed image is formed on the surface of the drum by applying laser beam.
3. Development: Toner is adhered to the surface of the drum.
4. Transfer: The toner on the surface of the exposure drum is transferred to paper.
5. Fusing: The transferred toner is fused into place on the paper.
After these processes, the image is printed on the paper.

3.5.2 Print Process
(1) Charging
The flow of the ion charge is controlled by constant voltage of the grid 850 V to ensure it is
distributed evenly on the drum surface. In order to coat toner on the exposure drum, the
drum needs to be evenly electrified. Ions are produced by supplying high-voltage power to
the corona wire.

Memo :
• The level of ozone expelled from the machine is less than 3.0 mg/h therefore not
harmful to the human body. Applicable safety standards have been complied.
2-26
Confidential
(2) Exposure
The laser beam radiated from a laser diode inside the laser unit is concentrated into a
constant width by a slit in the CO lens cell and then reflected by a polygon mirror rotating at
high speed. The evenly charged exposure drum is irradiated with reflected light and exposed.
Surface potential is lowered by such exposure and a printed image is formed.

Polygon mirror

Exposure drum

(3) Development
Toner is attracted to a printed-image area on the exposure drum where surface potential is
lowered due to exposure.
By controlling developing bias voltage supplied to the develop roller, the amount of toner
taken to the drum is adjusted to keep printing density constant.

(5) Fusing
The toner transferred on paper passes between the heat roller and the pressure roller in the
fuser unit, being fused by heat and pressure. The thermistor detects surface temperature of
the heat roller and turns ON/OFF the halogen heater lamp. The temperature is kept constant.

1. INTRODUCTION
Troubleshooting is the countermeasure procedures that the service personnel should follow
if an error or malfunction occurs with the machine. It is impossible to anticipate all of the
possible troubles which may occur in future and determine the troubleshooting procedures,
so this chapter covers some sample troubles. However, those samples will help the service
personnel pinpoint and repair other defective elements.
1.1 Precautions
Be sure to observe and follow all the precautions to prevent any secondary problems from
happening during troubleshooting.
(1) Always turn off the power and unplug the power cable before removing any covers or
PCBs, adjusting the machine and so on. If you need to take voltage measurements with
the power switched on, take the greatest of care not to receive an electric shock.
(2) When connecting or disconnecting cable connectors, make sure that you hold the
connector body and not the cables.
(3) Electronic devices are sensitive to static build up; make sure that you touch a metal
portion of the machine to discharge yourself before accessing the PCBs.
Handle PCBs with care when repairing them.
(4) Follow the warning by all means.
warning
The fuser unit becomes extremely hot during operation. Wait until it has cooled down
sufficiently before replacing consumable items. DO NOT remove or damage the
caution label located on or around the fuser.
(5) Verify again that the repaired portion works properly.

1.3 Initial Check
Check the following items before attempting to repair the machine.
■ Operating Environment
(1) Put your machine on a flat, stable surface such as a desk that is free of vibration and
shocks.
(2) Use the machine in a well-ventilated room; use the machine within the following ranges
of temperature and humidity: temperature between 10°C and 32.5°C (50°F to 90.5°F),
and the relative humidity is maintained between 20% and 80%.
(3) The machine is not exposed to direct sunlight, excessive heat, moisture, or dust.
■ Power Supply
(1) The AC input power supply described on the rating plate of the machine should be within
±10% of the rated voltage.
(2) The AC input power supply is within the regulated value.
(3) The cables and harnesses are connected correctly.
(4) The fuses are not blown.
■ Paper
(1) A recommended type of paper is being used.
(Refer to "2.6.2 Media specifications" in Chapter 1.)
(2) The paper is not damp.
(3) The paper is not short-grained paper or acid paper.
■ Consumable Parts
(1) The drum unit (including the toner cartridge) is installed correctly.
■ Others
(1) Condensation
When the machine is moved from a cold place into a warm room, condensation may
occur inside the machine, causing various problems as listed below.
• Condensation on the optical surfaces such as the scanner window, lenses, the
reflection mirror and the protection glass may cause the print image to be light.
• If the exposure drum is cold, the electrical resistance of the photosensitive layer is
increased, making it impossible to obtain the correct contrast when printing.
• Condensation on the charge unit may cause corona charge leakage.
• Condensation on the plate and separation pad may cause paper feed failures.
If condensation has occurred, leave the machine for at least 2 hours to allow it to reach
room temperature.
If the drum unit is unpacked soon after it is moved from a cold place to a warm room,
condensation may occur inside the unit which may cause incorrect images. Instruct the
end user to allow the unit to come to room temperature before unpacking it. This will take
one or two hours.
