The contents are subject to change without notice.
CAUTION
This product is a class 1 laser product that complies with 21CFR 1040 of the CDRH standard and
IEC825. This means that this machine does not produce hazardous laser radiation. The use of controls,
adjustments or performance of procedures other than those specified herein may result in hazardous
radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved
on the eye’s retina, there is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of
servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a
unit, not as individual parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, toner
cartridge, and drum cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected
when removing and installing the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

before use.
Do not install your copier in areas that are:
• damp, humid, or very dusty
• exposed to direct sunlight
2. Cautions on handling
Be careful in handling the copier as follows to maintain the performance of this copier.
Do not drop the copier, subject it to shock or strike it against any
object.
Do not expose the drum cartridge to direct sunlight.
Doing so will damage the surface (green portion) of the drum cartridge,
causing poor print quality.
• poorly ventilated
• subject to extreme temperature or humidity changes, e.g., near an
air conditioner or heater.
The copier should be installed near an accessible power outlet for easy
connection.
Be sure to connect the power cord only to a power outlet that meets
the specified voltage and current requirements.
Also make certain the outlet is properly grounded.
Be sure to allow the required space around the machine for servicing
and proper ventilation.
Store spare supplies such as drum cartridges and TD cartridges in a
dark place without removing from the package before use.
If they are exposed to direct sunlight, poor print quality may result.
Do not touch the surface (green portion) of the drum cartridge.
Doing so will damage the surface of the cartridge, causing poor print
quality.

2. Outline of print process
This printer is a non-impact printer that uses a semiconductor laser
and electrostatic print process. This printer uses an OPC (Organic
Photo Conductor) for its photoconductive material.
First, voltage from the main corona unit charges the drum surface and
a latent image is formed on the drum surface using a laser beam. This
latent image forms a visible image on the drum surface when toner is
applied. The toner image is then transferred onto the print paper by the
transfer corona and fused on the print paper in the fusing section with
a combination of heat and pressure.
Step-1: Charge
Step-2: Exposure
* Latent image is formed on the drum.
Step-3: Developing
Latent image formed on the drum is then changed into visible
image with toner.
Step-4: Transfer
The visible image (toner image) on the drum is transferred
onto the print paper.
Step-5: Cleaning
Residual toner on the drum surface is removed and collected
by the cleaning blade.
Step-6: Optical discharge
Residual charge on the drum surface is removed, by
semiconductor laser beam.
3. Actual print process
Step-1: DC charge
A uniform negative charge is applied over the OPC drum surface by
the main charging unit. Stable potential is maintained by means of the
Scorotron charger.
Positive charges are generated in the aluminum layer.
Step-2: Exposure (laser beam, lens)
A Laser beam is generated from the semiconductor laser and
controlled by the print pattern signal. The laser writes onto the OPC
drum surface through the polygon mirrors and lens. The resistance of
the OPC layer decreases for an area exposed by the laser beam
(corresponding to the print pattern signal). The beam neutralizes the
negative charge. An electrostatic latent image is formed on the drum
surface.

Step-3: Developing (DC bias)
A bias potential is applied to the MG roller in the two component
magnetic brush developing method, and the toner is charged negative
through friction with the carrier.
Non-image area of the drum surface charged with negative potential
repel the toner, whereas the laser exposed portions where no negative
charges exist, attract the toner. As a result, a visible image appears on
the drum surface.

Step-5: Separation
Since the print paper is charged positively by the transfer corona, it is
discharged by the separation corona. The separation corona is
connected to ground.
Step-6: Cleaning
Toner remaining on the drum is removed and collected by the cleaning
blade. It is transported to the waste toner collecting section in the
cleaning unit by the waste toner transport roller.
AL-1457 COPY PROCESS 6 - 3
Step-7: Optical discharge (Semiconductor laser)
Before the drum rotation is stopped, the semiconductor laser is
radiated onto the drum to reduce the electrical resistance in the OPC
layer and eliminate residual charge, providing a uniform state to the
drum surface for the next page to be printed.
When the electrical resistance is reduced, positive charges on the
aluminum layer are moved and neutralized with negative charges on
the OPC layer.
Semiconductor laser
Charge by the Scorotron charger
Function
The Scorotron charger functions to maintain uniform surface potential
on the drum at all times, It control the surface potential regardless of
the charge characteristics of the photoconductor.
Basic function
A screen grid is placed between the saw tooth and the
photoconductor. A stable voltage is added to the screen grid to
maintain the corona current on the photoconductor.
As the photoconductor is charged by the saw tooth from the main
corona unit, the surface potential increases. This increases the current
flowing through the screen grid. When the photoconductor potential
nears the grid potential, the current turns to flow to the grid so that the
photoconductor potential can be maintained at a stable level.
Start
1) Because the grid potential is at a low level, the drum potential is at
about -400V. (Carrier may not be attracted though the carrier is
pulled towards the drum by the electrostatic force of -400V.
2) Developing bias (-400V) is applied when the photoconductor
potential is switched from LOW to HIGH.
3) Once developing bias (-400V) is applied and the photo conductor
potential rises to HIGH, toner will not be attracted to the drum.
Stop
The reverse sequence takes place.
Retaining developing bias at an abnormal occurrence
Function
The developing bias will be lost if the power supply was removed
during print process. In this event, the drum potential slightly abates
and the carrier makes deposits on the drum because of strong static
power. To prevent this, the machine incorporates a function to retain
the developing bias for a certain period and decrease the voltage
gradually against possible power loss.
Basic function
Normally, the developing bias voltage is retained for a certain time
before the drum comes to a complete stop if the machine should stop
before completing the normal print cycle. The developing bias can be
added before resuming the operation after an abnormal interruption.
Therefore, carrier will not make a deposit on the drum surface.
Process controlling
Function
The print pattern signal is converted into an invisible image by the
semiconductor laser using negative to positive (reversible) developing
method. Therefore, if the developing bias is added before the drum is
charged, toner is attracted onto the drum. If the developing bias is not
added when the drum is charged, the carrier is attracted to the drum
because of the strong electrostatic force of the drum.
To avoid this, the process is controlled by adjusting the drum potential
and the grid potential of the Scorotron charger.
Basic function
Voltage added to the screen grid can be selected, high and low. To
make it easily understood, the figure below shows voltage transition at
the developer unit.

switch (PPD1), and detected by it. After about 0.15 sec from
detection of paper by PPD1, the tray paper feed solenoid (PFS)
turns on so that the clutch sleeve projection comes into contact
with the paper feed latch to stop the pick-up roller. Then the pickup roller rotates for about 0.15 sec so that the lead edge of the
paper is evenly pressed on the resist roller, preventing against
skew feeding.

3) After about 0.1 sec from when the main motor start rotating, the
tray paper feed solenoid (PFS) turns on for a moment.
This disengages the paper feed latch from the projection of the
clutch sleeve, transmitting rotation of the pick-up drive gear to the
paper feed roller shaft, rotating the pick-up roller to feed the paper.

6) To release the resist roller, the tray paper feed solenoid and the
resist solenoid are turned on by the paper start signal to disengage
the resist start latch from the clutch sleeve, transmitting rotation of
the resist drive gear to the resist roller shaft. Thus the paper is
transported by the resist roller.
7) After the resist roller starts rotating, the paper is passed through
the pre-transfer guide to the transfer section. Images are
transferred on the paper, which is separated from the OPC drum
by the drum curve and the separation section.

4) After more than half rotation of the pick-up roller, the paper feed
latch is brought in contact with a notch on the clutch sleeve,
stopping rotation of the pick-up roller.

1) Before paper feed operation, the manual paper feed solenoid
(MPFS) is turned OFF as shown in the figure below.

operation from the tray. (Refer to A-5 - 8.)

A. Copy magnification ratio adjustment
The copy magnification ratio must be adjusted in the main scanning
direction and in the sub scanning direction. To adjust, use SIM 48-1.
(1) Outline
The main scanning (front/rear) direction magnification ratio adjustment
is made automatically or manually.
Automatic adjustment: The width of the reference line marked on the
shading correction plate is scanned to perform the main scanning
(front/rear) direction magnification ratio adjustment automatically.
Manual adjustment: The adjustment is made by manual key
operations. (In either of the automatic and manual adjustments, the
zoom data register set value is changed for adjustment.)
The magnification ratio in the sub scanning direction is adjusted by
changing the carriage (scanner) scanning speed.
(2) Main scanning direction magnification ratio adjustment
a. Cases when the adjustment is required
1) When the main PWB is replaced.
2) When the EEPROM in the main PWB is replaced.
3) When "U2" trouble occurs.
4) When repairing or replacing the optical section.
b. Necessary tools

(3) Image process ASIC (HG73C119HF)
a. General
The ASIC is composed of the three major blocks: the image process
section, the print control section, and the I/F section.
Image process section:
With image data from the CCD PWB in the operation mode determined by the register setup, shading, AE process, input γ correc-
tion, area separation, filter process, resolution conversion, zoom
process, output γ correction, binary conversion (error diffusion,
dither method, simple binary conversion) are performed.
Print control section:
When copying, the image-processed data are outputted to the LSU
according to the LSU writing timing. When scanning, the image
data are made into 8bit width and outputted to the I/F section
(USB).
I/F section:
Controls the DRAM which is the image data buffer, and processes
data send/receive between the USB I/F and the IEEE1284 I/F.
The ASIC is controlled by writing the operation mode and the necessary setup values of the operation mode into the ASIC control register
before starting each operation. (For ASIC Pin configuration, refer to the
table at the end of this document.)

Thermistor
Heat Roller
The lower the heat roller surface temperature is, the greater the thermistor resistance is, and vise versa.
Therefore, the lower the heat roller surface temperature is, the higher
the thermistor terminal voltage is, and vise versa. The thermistor terminal voltage is inputted to the CPU analog port.
The CPU controls ON/OFF of the heater lamp by this input voltage
level.
AL-1457 ELECTRICAL SECTION 12 - 8
[High temperature protect circuit in case of CPU hung up]
For IC120 3pin (reference voltage), +3.3V is divided by the resistor.
The thermistor terminal voltage is inputted to IC120 2pin.
When, the voltage at 2pin becomes lower than the voltage at 3pin
(when the heat roller temperature is about 220 – 230°C), IC120 1pin
becomes HIGH, and the HL signal is lowered to the GND potential
through IC124, stopping generation of the heater lamp ON signal.
(IC120 1pin is normal LOW.)
[When the heat roller surface temperature is lower than the set
level]
1) Since the thermistor terminal voltage is higher than the set level,
the HL signal from the CPU becomes HIGH.
2) The HL signal is turned to be the HLOUT signal through IC124 protect circuit, and inputted to the photo triac coupler on the power
PWB.
3) When the internal triac turns on, a pulse is applied to the gate of the
external triac. Consequently a current flow from the power source
through the heater lamp to the triac, lighting the heater lamp.
[When the heat roller surface temperature is higher than the set
level]
1) Since the thermistor terminal voltage becomes lower than the set
value, the HL signal from the CPU becomes LOW.
2) The HL turns LOW, the photo triac coupler on the power PWB turns
OFF, the external triac turns OFF, and the heater lamp turns OFF.
[In case of the thermistor open]
The voltage at IC120 6pin over the voltage at 5pin to drive the output
THOPEN at 7pin to LOW. This is passed to the CPU and the trouble
code "H2" is displayed.
(6) Toner supply motor drive circuit
The IC129 is the motor control IC, which generates the pseudo AC
waveform with the pulse signals (TM, TM-) outputted from ASIC, driving the toner supply motor.
(5) Driver circuit (Solenoid)
a. Outline
Since the load signal from the CPU or the ASIC cannot drive the load
directly, it is passed through the driver IC to drive the load.
b. Operation
The driver circuit forms a Darlington circuit with transistors. Therefore a
large drive current is obtained from a small current (ASIC output current). When the driver input voltage (base resistance input) is HIGH
(+3.3V), the transistor turns ON to flow a current in the arrow direction,
operating the load. When the driver is ON, the driver output terminal
voltage is 0V.

(7) Main motor drive circuit
The main motor is driven by the MMD signal from ASIC. While the
main motor is rotating, the MMD signal is driven to HIGH and passed
through IC125 to the control circuit in the main motor to rotate the main
motor. When the main motor speed reaches the specified rpm, the
MMLD signal is turned LOW and passed through IC115 to the CPU.

(8) Mirror motor control circuit, Duplex motor control circuit
Stepping motors are employed for the mirror motor, the SPF motor,
and the duplex motor. The driver for IC127 (for mirror motor) is the
bipolar drive L6219DS, and the driver for IC128 (for SPF) is the unipolar drive IC MTD1361F. For control, the SPF outputs the drive signal
from the CPU to the IC, and the mirror outputs the drive signal to the IC
with the ASIC. They drive each motor in 1-2 phase excitement or 2phase excitement.
Each motor switches the motor current value in each magnification
ratio.

The DC power circuit directly rectifies the AC power and performs
switching-conversion with the DC/DC converter circuit, and rectifies
and smoothes again to generate a DC voltage.
The constant voltage control circuit is of +5VEN. +24V and +12V are of
the non-control system by winding from the +5VEN winding. As shown
in fig (1), +24V, +12V, and +5V are provided with the ON/OFF function
by external signals. +3.3V is outputted from +5VEN to the regulator IC.
Refer to the block diagram, fig (1).

(1) Noise filter circuit
The filter circuit is composed of L and C. It reduces common noises
and normal mode noises generated from the AC line.
The common noise means that generated in each line for GND. Its
noise component is delivered through C001, C003, and C007 to GND.
The normal noise means that overlapped in the AC line or the output
line. It is attenuated by C002, L001, C006, and L002. Refer to fig (2).

fig (4) Inverter and control circuit
This circuit is one-stone separate excitation DC-DC converter called
flyback converter, as shown in fig (4).
When an electromotive voltage of IC is applied through D012, R005,
and R006 to IC002, IC002 oscillates to conduct Q001.
As a result, a voltage is applied to the primary winding of the converter
transformer (T001) and at the same time a voltage is generated in the
driving winding of IC002 to operate IC002. Then IC002 turns ON/OFF
Q001 at the frequency of about 70KHz determined by R016.
Under the ON state, the voltage in the secondary winding is reversed
to the diode D103 and no current flows through the secondary winding
of T001.
Under the OFF state, the current flowing through the primary winding is
in the same direction as the primary winding, conducting D103 and
transmitting energy to the secondary winding. Refer to fig (4).
fig (3) Rush current prevention, rectifying/smoothing circuit
Since the AC power is directly rectified, if there were not this rush current prevention resistor (TH001), an extremely large rush current
would flow due to a charging current flowing through the smoothing
capacitor C010 when turning on the power.
To prevent against this, the rush current prevention resistor TH001 is
provided between the rectifying diode D002 and the smoothing diode
C010, suppressing a rush current.
The rectifying/smoothing circuit rectifies a 50/60Hz AC voltage with the
rectifying circuit, and smoothes it with the smoothing capacitor C010.

AL-1457 ELECTRICAL SECTION 12 - 12
The control circuit is subject to negative feedback from the secondary
side as shown in fig (4). A photo coupler (PC002) is employed to insulate between the primary side and the secondary side to feed back the
control signal to the primary side.
When the output voltage is increased by energy transmission from
T001, the voltage detected by R109 and R111 is compared with the
reference voltage of IC102. When it exceeds the reference voltage, the
current flowing through IC102 (that is, the photo diode current of
PC002) is increased and transmitted to the primary side. Then the
potential at the feedback pin (2 pin) of IC102 is decreased to control
Q001. Therefore, the change in the output voltage on the secondary
side is passed through IC102 and PC002 to control Q001, stabilizing
the output voltage.
(4) Overcurrent protection circuit (Primary side)
The inverter circuit of the primary side is connected with the current
detection resistor R102. When an overcurrent occurs in the secondary
side, the current flowing through the primary side inverter Q001 is
increased. The current is detected by R012, and passed through R013
to IC701 overcurrent restricting pin (3 pin) to turn OFF Q002, shutting
off all power. To resupply the power, turn off and on the power. Refer
to fig (4).
(5) Rectifying/smoothing circuit (+5V)
fig (6) Rectifying/smoothing circuit
The high frequency pulse generated by the inverter circuit is
decreased by the converter transformer, rectified by the high frequency
diode D103, and smoothed by C103 and C104.
