This document has been published to be used 

for after sales service only. 

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. 

LASER WAVE – LENGTH : 770 ~ 795nm 

Pulse times : 11.82µs/7mm 

Out put power : 0.17mW ± 0.01mW 

CAUTION

At the production line, the output power 

of the scanner unit is adjusted to 0.57 

MILLI-WATT PLUS 20 PCTS and is 

maintained constant by the operation of 

the Automatic Power Control (APC). 

Even if the APC circuit fails in operation 

for some reason, the maximum output 

power will only be 15 MILLI-WATT 0.1 

MICRO-SEC. Giving and accessible 

emission level of 42 MICRO-WATT 

which is still-less than the limit of 

CLASS-1 laser product. 

The foregoing is applicable only to the 220V 

model, 230V model and 240V model.

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. 

About 

DC5.5KV 

( 580V/ 390V) 


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-4: Transfer 

The visible image on the drum surface is transferred onto the print 

paper by applying a positive charge from the transfer corona to the 

backside of the print paper. 

About DC 5.2kV 

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.

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. 

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. 

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. 


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.

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. 


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.

2. Scanner section 

A. Scanner unit 

The scanner unit in the digital copier scans images. 

It is composed of the optical unit and the drive unit. The optical unit 

performs scanning in the main scan direction with the light receiving 

elements (color CCD). The drive unit performs scanning in the sub 

scanning direction by moving the optical unit. 

B. Optical system 

Two white lamps are used as the light source. 

Light radiated from the light source is applied to the document on the 

document table. The reflected light from the document is reflected 5 

times by No. 1 - No. 3 mirrors and passed through the reduction lens to 

form images on the light-receiving surface of 3-line CCD. 

The light-receiving surface of the color CCD is provided with 3 line 

scanning sections for RGB. Separate images scanned in each color 

section are overlapped to complete color scanning. (When PC scanning) 

The resolution is 600dpi. 

When copying, only the green component is used to print with the 

printer. 

The color component for printing can be switched to red or blue by the 

service simulation.

3. Laser unit 

The image data sent from the MCU (image process circuit) is sent to 

the LSU (laser unit), where it is converted into laser beams. 

A. Basic structure 

The LSU unit is the writing section of the digital optical system. 

The semiconductor laser is used as the light source, and images are 

formed on the OPC drum by the polygon mirror and fθ lens, etc. 

The laser beams are passed through the collimator lens, the cylindrical 

lens, the polygon mirror, the fθ lens, and the mirror to form images on 

the OPC drum in the main scanning direction. The laser emitting PWB 

is provided with the APC (auto power control) in order to eliminate fluctuations 

in the laser power. The BD PWB works for measurement of 

the laser writing start point.

(2) Separator pawl 

Three separator pawls are used on the upper heat roller. The separator 

pawls are Teflon coated to reduce friction with the roller and prevent 

a smear on the paper caused by the separator pawl. 

(3) Thermal control 

1) The heater lamp, thermistor, main PWB, DC power supply PWB, 

and triac within the power supply unit are used to control the 

temperature in the fuser unit. 

To prevent against abnormally high temperature in the fuser unit, a 

thermal breaker and thermal fuse are used for safety purposes.

2) The surface temperature of the upper heat roller is set to 165 - 

190°C. The surface temperature during the power save mode is 

set to 100°C. 

3) The self-check function comes active when one of the following 

malfunctions occurs, and an "H" is displayed on the multicopy 

window. 

a. When the heat roller surface temperature rises above 240°C. 

b. When the heat roller surface temperature drops below 100°C during 

the copy cycle.

(4) Fusing resistor 

Fusing resistor 

This model is provided with a fusing resistor in the fusing section to 

improve transfer efficiency. 

Since the upper heat roller is conductive, when using copy paper that 

contains moisture and the distance between the transfer unit and the 

fusing unit is short, the transfer current may find a path to ground via 

the copy paper, the upper heat roller and the discharging brush.

sheets. 

The front loading system allows you to install or remove the tray from 

the front cabinet. 

The general descriptions on the tray paper feed and the manual paper 

feed operation are given below.

(1) Cassette paper feed operation 

1) The figure below shows the positions of the pick-up roller, the 

paper feed clutch sleeve, and the paper feed latch in the initial 

state without pressing the COPY button after lighting the ready 

lamp. 

The paper feed latch is in contact with the projection of the clutch 

sleeve. 

2) When the COPY button is pressed, the main drive motor starts 

rotating to drive each drive gear. 

The pick-up drive gear also is driven at that time. Since, however, 

the paper feed latch is in contact with the projection of the clutch 

sleeve, rotation of the drive gear is not transmitted to the pick-up 

roller, which does not rotate therefore. 

PFS 

OFF 

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.

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. 


5) At this time, the paper is fed passed the paper entry detection 

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. 

PFS 

ON 

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.

1) Before paper feed operation, the manual paper feed solenoid 

(MPFS) is turned OFF as shown in the figure below.

2) When the PRINT button is pressed, the manual paper feed 

solenoid (MPFS) turns on to disengage the manual paper feed 

latch.

4) The lead edge of the transported paper is pressed on the resist 

roller by the transport roller. Then the paper is stopped temporarily 

to allow synchronization with the lead edge of the image on the 

OPC drum. 

From this point, the operation is the same as the paper feed 

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

[9] ADJUSTMENTS 


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 

• Screwdriver (+) 

Scale 

c. Adjustment procedure 

Automatic adjustment 

In the first place, perform SIM48-1 (Main scanning direction 

magnification ratio adjustment and black level correction (CCD dark 

component target value setup)). 

To perform the automatic adjustment, place the gray gradation chart 

(UKOG-0162FCZZ) face down so as to fit with the left center of the 

platen with the darker side (Density 10) on the left of OC. 

10 1 

Back of the chart 

In the case of the automatic adjustment, when the PRINT switch is 

pressed, the mirror base unit moves to the white plate for shading to 

scan the width of the reference line, calculating the correction value 

and displaying and storing this value. 

After completion of the automatic adjustment, press the density 

adjustment Down key, and the black level will be displayed in 

hexadecimal number (3 digits) of 12bits. 

After execution of the automatic adjustment, go out from the simulation 

mode and make a copy to check the magnification ratio.

6) Check that the copy magnification ratio is within the specified 

range. If it is not within the specified range, perform the following 

procedures. 

7) Execute SIM 48-1 to select the main scanning direction copy 

magnification ratio adjustment mode. 

To select the adjustment mode, use the copy mode select key. 

If the magnification ratio is not in the specified range (100±1.0%), 

manually adjust as follows. 

8) Set the adjustment mode to Manual with the copy mode select key. 

9) Enter the new set value of main scanning direction copy 

magnification ratio with the copy quantity set key, and press the 

COPY button. 

10) Change the set value and repeat the adjustment until the ratio is 

within the specified range. 

When the set value is changed by 1, the magnification ratio is 

changed by 0.1%.

(1) Lead edge adjustment 

1) Set a scale to the center of the paper lead edge guide as shown 

below, and cover it with B4 or 8 1/2" x 14" paper. 

2) Execute SIM 50 - 01 

3) Set the print start position (AE lamp ON) (A), the lead edge void 

amount (TEXT lamp ON) (B), and the scan start position (PHOTO 

lamp ON) (C) to 0, and make a copy of a scale at 100%. 

4) Measure the image loss amount (R mm) of the scale image. 

Set C = 10 X R (mm). (Example: Set the value of C to 30.) 

When the value of C is increased by 10, the image loss is 

decreased by 1mm. (Default: 50) 

5) Measure the distance (H mm) between the paper lead edge and 

the image print start position. 

Set A = 10 X H (mm). (Example: Set the value of A to 50.) 

When the value of A is increased by 10, the image lead edge is 

shifted to the paper lead edge by 1mm. (Default: 50) 

6) Set the lead edge void amount to B = 50 (2.5mm). 

When the value of B is increased by 10, the void amount is 

increased by about 1mm. For 25 or less, however, the void amount 

becomes zero. (Default: 50) 

(Example) 

Distance between paper lead 

edge and image: H = 5mm

4) If the measurement value is out of the specified range, change the 

set value and repeat the adjustment procedure. 

The default value is 50. 

Note: The rear edge void cannot be checked with the first sheet after 

entering the simulation mode, the first sheet after turning off/on 

the power, or the first sheet after inserting the cassette. Use the 

second or later sheet to check the rear edge void. 

(3) Center offset adjustment 

1) Set the self-made test chart for the center position adjustment so 

that its center line is aligned with the center mark of the document 

guide.

4) If the measured value is out of the specified range, change the set 

value and repeat the adjustment procedure. 

When the set value is increased by 1, the copy image is shifted by 

0.1mm toward the rear frame. 

For the manual paper feed, change the manual paper feed 

adjustment mode and perform the similar procedures. 

Since the document center offset is automatically adjusted by the 

CCD which scan the reference lines (F/R) on the back of document 

guide, there is no need to adjust manually.

3. High voltage adjustment 

A. Main charger (Grid bias) 

Note: 


Use a digital multi meter with internal resistance of 10MΩ or more 

measurement. 

After adjusting the grid LOW output, adjust the HIGH output. Do not 

reverse the sequence. 

Procedures 

1) Set the digital multi meter range to DC700V. 

2) Set the positive side of the test rod to the connector CN11-3 

(GRID) of high voltage section of the power PWB and set the 

negative side to the frame ground (power frame). 

3) Execute SIM 8-3. (The main charger output is supplied for 30 sec 

in the grid voltage LOW output mode.) 

4) Adjust the control volume (VRG2) so that the output voltage is 

– 390 ±20V. 

5) Execute SIM 8-2. (The main charger output is supplied for 30 sec 

in the grid voltage HIGH output mode.) 

6) Adjust the control volume (VRG1) so that the output voltage is 580 

±12V. 

B. DV bias check 

VRG1

Note: A digital multi meter with internal resistance of 1GΩ must be 

use for correct check. 

The adjustment volume is locked, and no adjustment can be 

made. 

Procedures 

1) Set the digital multi meter range to DC500V. 

2) Set the positive side of the test rod to the connector CN-10-1 (DV 

BIAS) and set the negative side to the frame ground (power 

frame). 

3) Execute SIM 25-1 to output the developing bias for 30sec, and 

check that the output is – 400 ±8V. 

VRDV

4. Duplex adjustment 

A. Adjusting the paper reverse position in memory 

for duplex copying 

This step adjusts the front surface printing (odd-number pages of a 

document set) in the S-D mode copying and the leading edge position 

of an image on even-number pages in the D-S mode. 

That is, it covers the adjustment of the second surface printing mode 

(image loss at the front edge of an image) in which image data is once 

stored in memory. 

The image data is read, starting from its front end in the document 

delivery direction (Reference direction of document setting in the OC 

mode)and stored in memory. 

This stored image data is printed starting at the printing start position, 

in the order of last-stored data to the first-stored data. 

In other words, the front edge image loss of the image can be adjusted 

by changing the document read end position. 

(Adjustment procedure) 

1) Preparing test chart (Draw a scale at the rear end of one side of a 

sheet of A4 white paper or letter paper) 

5 10 

2) Set the test chart so that the scale is positioned as shown below, in 

the S-D mode and the D-S mode. 

Scale (S-D mode) Scale (D-S mode) 

3) Execute simulation 50-18 to make a copy and check the front edge 

image loss at the area where the scale is printed. 

Adjust the setting so that the front edge image loss is less than 4.0 

mm in the R-SPF mode. 

An increase of 1 in setting represents an increase of 0.1 mm in 

image loss.

Void area 


B. Adjusting trailing edge void in duplex copy mode 

This is the adjustment of the first surface printing mode (rear end void) 

in duplex copying. 

In a duplex copying operation, the paper is delivered starting from the 

rear end of the first printing surface. It is therefore necessary to make a 

void area at the rear end on the first printing surface to prevent paper 

jam at the fusing part. 

There are two adjustment modes: 

1) Image cut rear end void quantity (R-SPF) 50-19(AE) 

The size (length) of a document read from the R-SPF is detected, 

the image at the trailing edge of the first printing surface is cut to 

make a void area. (The adjustment of void quantity at the time 

when the cassette paper size is not recognized.) 

2) Paper trailing edge void quantity 50-19 (TEXT) 

This adjustment is made when the cassette paper size is 

recognized. The trailing edge void quantity can be adjusted by 

changing the trailing edge image laser OFF timing. 

The paper void quantity should be first adjusted before the image cut 

trailing edge void quantity (R-SPF) is adjusted. 


(1) Paper trailing edge void quantity 

1) Preparing test chart (Draw a scale at the rear end of one side of a 

sheet of A/4 white paper or letter paper) 

2) Set the test chart on the document glass as shown below. 

3) Using the user simulation [18], set the paper size of the first 

cassette. 

Letter paper: 4 

A4 paper: 3 

2nd printing surface where scale is printed (lower side)

4) Execute simulation 50-19 to turn on the TEXT lamp and make the 

printing mode in OC-D mode. 

Make a copy of the test chart to check the void area of the scale on 

the image. 

Paper 

Void position to be check 

The trailing edge void on the first printing surface 

is shown above. 

Adjust the setting so that the void area is 4 - 5 mm. An increase in 1 of 

setting represents 0.1 mm in void area. 

(2) Image cut trailing edge void quantity (R-SPF) 

1) Set the test chart so that the scale is positioned as shown below. 

Scale (D-D mode) 

2) Execute simulation 50-19 to turn on the AE lamp(on the operation 

panel) and make the printing mode in the D-D mode. 

3) Remove and reinsert the cassette. 

Note: Make sure to carry out this step before making a copy during 

this adjustment. 

4) Make a copy and check the void area of the scale on the image. 

Adjust the setting so that the void area is 2 - 4 mm. An increase of 

1 in setting represents an increase of 0.1 mm in void area.

document rear edge section. 

When, therefore, the output image print position adjustment is required, adjust as follows: 

In the reverse memory copy operation, if the document scan direction is in the direction of the arrow in the figure, the scan rear edge 

section of the image is printed first. 

When, therefore, the print lead edge is shifted, set the reference chart so that the reference position is in the rear edge section, and use 

this simulation to adjust so that the print image lead edge comes to the lead edge. 

Since printing is performed by processing the scanned image from the scan end position to the scan lead edge, the print lead edge 

position adjustment is performed by changing the end data position stored in memory with the simulation setup value.

(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 correction, 

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.)

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.

This circuit detects ON/OFF of power to control start/stop of each circuit. 

The 3.3V voltage of the main PWB is detected by the reset IC to 

generate the reset signal. 

When the power voltage reaches the specified level, the circuit operations 

are started. Before the power voltage falls below the specified 

level, the circuit operations are stopped to prevent against malfunctions.

[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.)

Control)

[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

(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.

(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.

(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.

Image data scanned by the CCD are inputted to the AFE (AD9826), 

and subject to CDS, amplification, and AD-conversion. Then digital 

data are outputted to the MCU PWB and to the ASIC, which performs 

image process of the digital data. 

c. Lamp inverter PWB 

The transformer is controlled by the lamp control signal from the MCU 

PWB. The transformer output controls lighting of the cool cathode ray 

tube. 

B. DC power circuit 

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).

(2) Rush current prevention circuit and rectifying/ 


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.

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).

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.
