It is possible to get harmed from noxious material if you ignore the below information.
(1) Do not touch the damaged LCD. This PRINTER has LCD in control panel. Noxious liquid to human body exists in the
LCD. If it is got into mouth, immediately see a doctor. If it is got into eyes or on skin, immediately wash off over 15
minutes with flowing water and see a doctor.
(2) The toner in a printer cartridge contains a chemical material, which might harm human body if it is swallowed.
Please keep children out of the toner cartridge.
1.2.2 Precaution related electric shock or fire
It is possible to get electric shock or burn by fire if you don't follow the instructions of the manual.
(1) Use exact voltage. Please do use an exact voltage and wall socket. If not, a fire or an electric leakage
can be caused.
(2) Use authorized power code. Do use the power code supplied with PRINTER. A fire can be occurred
when over current flows in the power code.
(3) Do not insert many cords into a outlet. If do, a fire can occur due to a over flow of current in an outlet.
(4) Do not put water or extraneous matter in the PRINTER. Please do not put water, other liquid, pin, clip,
etc. It can cause a fire, electric shock, or malfunction. If it happens, turn off the power and remove the
power plug from outlet immediately.
(5) Do not touch the power plug with a wet hand. When servicing, remove the power plug from the outlet
and do not insert or remove it with a wet hand. Electric shock can occur.
(6) Use caution when inserting or taking off the power plug. The power plug has to be inserted completely.
If not, a fire will be caused due to poor contact. When taking off the power plug, grip the plug and
remove it.
(7) Management of power cord. Do not bend, twist, bind or place other materials on it. Do not use stales
around printer. If the power code gets damage, a fire or electric shock can occur. A damaged power
code must be replaced immediately. Do not repair the damaged part or reuse it. Repairing cord with
plastic tape can cause a fire or electric shock. Do not spread chemicals on the power code. Do not
spread insecticide on the power code. A fire or electric shock can occurred due to a thin(weak) cover on
the power code.
(8) Check whether the power outlet and the power plug are damaged, pressed or chopped. When such
inferiorities are found, repair it immediately. Do not press or chop the cord when moving the machine.
(9) Use caution during thunder or lightning storms. It may cause fire or electric shock. Take the power plug
off under these conditions. Do not touch cable and device duing thender or lightening storms.
(10) Avoid damp or dusty areas. Do not install the printer in dusty areas or around humidifiers. A fire can
occurr. Clean plug well with dried fabric to remove dust. Fire can occur if water is dropped into the unit
or if coverd with dust.
(11) Avoid direct sunlight. Do not install the printer near to a window where it directly contacts to the sunlight. If the machine contacts sunlight for a long time, the machine will not work properly, because the
inner temperature of machine will get higher. A fire can beoccur.
(12) Turn off the power and take off the plug when smoke, a strange smell, or sound from the machine is
detected. A fire can occur if unit is used under these conditions.
(13) Do not insert steel or metal pieces inside/outside of the machine. Do not put steel or metal piece into
the ventila-tor. An electric shock can occur.

Precautions
1.3 ESD Precautions
Certain semiconductor devices can be easily damaged by static electricity. Such components are commonly
called “Electrostatically Sensitive (ES) Devices”, or ESDs. Examples of typical ESDs are: integrated circuits,
some field effect transistors, and semiconductor “chip” components.
The techniques outlined below should be followed to help reduce the incidence of component damage caused
by static electricity.
Caution >>Be sure no power is applied to the chassis or circuit, and observe all other safety precautions.
1. Immediately before handling a semiconductor component or semiconductor-equipped assembly, drain off
any electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially available wrist strap device, which should be removed for your personal safety reasons prior to applying power to the unit under test.
2. After removing an electrical assembly equipped with ESDs, place the assembly on a conductive surface,
such as aluminum or copper foil, or conductive foam, to prevent electrostatic charge buildup in the vicinity
of the assembly.
3. Use only a grounded tip soldering iron to solder or desolder ESDs.
4. Use only an “anti-static” solder removal device. Some solder removal devices not classified as “anti-static”
can generate electrical charges sufficient to damage ESDs.
5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufficient to
damage ESDs.
6. Do not remove a replacement ESD from its protective packaging until immediately before installing it. Most
replacement ESDs are packaged with all leads shorted together by conductive foam, aluminum foil, or a
comparable conductive material.
7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch
the protective material to the chassis or circuit assembly into which the device will be installed.
8. Maintain continuous electrical contact between the ESD and the assembly into which it will be installed,
until completely plugged or soldered into the circuit.
9. Minimize bodily motions when handling unpackaged replacement ESDs. Normal motions, such as the
brushing together of clothing fabric and lifting one’s foot from a carpeted floor, can generate static electricity sufficient to damage an ESD.

SUMMARY OF PRODUCT
4.3.4 Sensor input circuit
1) Paper Empty Sensor
The Paper empty sensor (Photo Interrupter) on the engine board informs the state of paper to
CPU, whether it is empty or not with operation of the actuator.
It detects a paper empty state by reading the D0 Bit of CPU, and then informs this fact by selecting
the second LED(yellow) among the panel LEDs.
2) MP Sensing
By operation of Actuator on the frame, the MP Sensor (Photo Interrupter) on the power
board(SMPS) informs the state of paper to CPU whether it is empty or not. It reads the D0 Bit of
CPU for recognizing paper in MP, and paper is fed from MP if there is.
3) Paper Feeding, Toner Cartridge Sensing
When paper passes the actuator (feed sensor part), it detects the signal of Photo interrupter,
informs the paper feeding state to the CPU, and then sends the image data after a certain time. If it
doesn't detect the feed sensor within 1 sec. after paper is fed, paper Jam0 occurs (Red and Yellow
will be turned on among the OP panel LEDs), and whether the developer is inserted or not is
detected with the same principle. After the developer is mounted, the actuator is operated. The signal from the photo interrupter is detected when it is passing the actuator of the sensor part. That
process is called developer ID sensing.
4) Paper Exit Sensing
It detects paper state whether paper gets out from the set with operation of exit sensor on the
engine board and actuator on the frame. Paper detects the on/off time of exit sensor, and the normal operation or jam information is informed to the CPU.
The paper JAM2 is informed.
5) Cover Open Sensing
The Cover open sensor is located on the front cover. After the front cover is opened, +24V (DC fan,
solenoid, main motor, polygon motor part of LSU, HVPS), which is supplied to the each unit, is cut off.
The cover-open sensing is operated by the D0 bit of CPU, and the developer ID sensing is operated.
6) DC FAN / SOLENOID Driving
It is driven by transistor and controlled by D6 bit of CPU.
When it is high, the fan is driven by turning on the TR, and it is off when the sleep mode is selected. There are two solenoids, and they are driven by the paper pick-up and MP signal. Its drive time
is 300ms. The diode protects the driving TR from the noise pulse, which is emiited when the solenoid is de-energizing.
7) Motor Driving
The motor driving circuit is formed when the Driver IC is selected. The A3977 (Motor driver IC) is
used in this case. The resistance Rs value of sensing and the voltage value of the V reference can
be changed by the motor driving voltage value.

SUMMARY OF PRODUCT
4.4.1 HVPS(High Voltage Power Supply)
1) Transfer High Voltage (THV+)
- Function : Voltage to transfer developed toner on OPC drum to a paper.
- Output voltage : +1300V DC±20V
- Error : If THV (+) doesn't output, a ghost status (same character is printed after one cycle (76mm)
of OPC) with a low density occurs due to a toner on OPC drum cannot normally transfer to
a paper.
2) Charge Voltage (MHV)
- Function : It is a voltage to charge entire surface of OPC with -900V ~ -1000V.
- Output voltage : -1550V DC ± 50V
- Error : If MHV doesn't output, a black paper is printed out because toner on developing roller
moves to OPC drum due to the surface of OPC not being charged.
3)Cleaning Voltage (THV-)
- Function : It removes a dirty on a surface by sending a minus toner in a transfer roller to an OPC
drum to recover toners.
- Output Voltage : +300V/-150V
- Error : Toner contamination occurs at the backside of a printed-paper.
4) Developing Voltage (DEV)
- Function: It is a voltage to develop a toner with using a difference of electronic potential on an
exposed part by LSU (Laser Scanning Unit).
* Generally, the electronic potential of exposed OPC is -180V and exposed developer is -350V
when printing, so toner with minus (-) is developed on an exposed part.
- Output voltage: -430V DC ± 20V
- Error: 1. If DEV is GND, a density is going significantly down.
2. If DEV is floating due to instable contacting point of terminal, and etc., a density is significantly going up.
5) Supply Voltage (SUP)
- Function: It is a voltage to supply toner to a developing roller.
- Output voltage: : -630V DC ± 50V (Use ZENER, DEV Gear)
- Error: 1. If SUP is GND, a density is dramatically going down.
2. If SUP is floating due to instable contacting point of terminal, and etc., a density is significantly going down as much as it cannot be recognized with eyes.

4.4.3 Fuser AC Power Control
Fuser (HEAT LAMP) gets heat from AC power. The AC power controls the switch with the Triac, a semiconductor switch. The 'On/Off control' is operated when the gate of the Triac is turned on/off by Photo triac
(insulting part).
In the other words, the AC control part is passive circuit, so it turns the heater on/off with taking signal from
engine control part.
When the 'HEATER ON' signal is turned on at engine, the LED of PC1 (Photo Triac) takes the voltage and
flashes. From the blinking light, the Triac part (light receiving part) takes the voltage, and the voltage is supplied to the gate of Triac and flows into the Triac. As a result, the AC current flows in the heat lamp, and
heat is occurred.
On the other hand, when the signal is off, the PC1 is off, the voltage is cut off at the gate of Triac, the Triac
becomes off, and then the heat lamp is turned off.

SUMMARY OF PRODUCT
4.5 Engine F/W
4.5.1 Feeding
If feeding from a cassette, the drive of the pickup roller is controlled by controlling the solenoid. The on/off
of the solenoid is controlled by controlling the general output port or the external output port. If feeding
from a manual feeder, insert the paper according to the operation of the manual sensor, and by driving the
main motor, insert the paper in front of the feed sensor. While paper moves, occurrence of jam is judged
as below. (Refer to the [6.2 Paper Transfer rout])
4.5.1.1 Jam 0
• After picking up, paper cannot entered due to paper didn’t feed.
• After picking up, paper entered but it cannot reach to the feed sensor in certain time due to slip, etc.
• After picking up, if the feed sensor is not on, repack up. After repacking up, if the feed sensor is not on
after certain time, it is Jam 0.
- It is a status that the leading edge of the paper doesn’t pass the feed sensor.
• Even though the paper reaches the feed sensor, the feed sensor doesn’t turn on.
- It is a status that the leading edge of the paper already passes the feed sensor.
4.5.1.2 Jam 1
• After the leading edge of the paper passes the feed sensor, the tailing edge of the paper cannot pass the
feed sensor after certain time. (The feed sensor cannot be Off)
• After the leading edge of the paper passes the feed sensor, the paper cannot reach the exit sensor after
certain time. (The exit sensor cannot be On)
- The paper exists between the feed sensor and the exit sensor.
4.5.1.3 Jam 2
• After the tailing edge of the paper passes the feed sensor, the paper cannot pass the exit sensor after
certain time.
4.5.2 Drive
By gearing, the main motor drives the rollers such as feeding roller, developing roller, fuser roller, and distributing roller. The step motor is controlled for the sections, acceleration section and fixed speed section.
In the initial stage of the motor run, appoint the acceleration section to prevent the isolation of the motor. It
is controlled by the A3977 motor driver IC. The step signal and the enable signal are sent to make the
phase for driving the motor in CPU.
4.5.3 Transfer
The charging voltage, developing voltage and the transfer voltage are controller by PWM (Pulse Width
Modulation). The each output voltage is changeable due to the PWM duty. The transfer voltage admitted
when the paper passes the transfer roller is decided by environment recognition. The resistance value of
the transfer roller is changed due to the surrounding environment or the environment of the set, and the
voltage value, which changes due to the environments, is changed through AD converter. The voltage
value for impressing to the transfer roller is decided by the changed value.

SUMMARY OF PRODUCT
4.5.4 Fusing
The temperature change of the heat roller’s surface is changed to the resistance value through the thermistor. By converting the voltage value, which impressed to the resistance, to the digital value through the AD
converter, the temperature is decided. The AC power is controlled by comparing the target temperature to
the value from the thermistor. If the value from the thermistor is out of the controlling range while controlling
the fusing, the error stated in the table occurs.

5.1 General Precautions on Disassembly
When you disassemble and reassemble components, you must use extreme caution. The close
proximity of cables to moving parts makes proper
routing a must.
If components are removed, any cables disturbed
by the procedure must be restored as close as
possible to their original positions. Before removing any component from the machine, note the
cable routing that will be affected.
Releasing Plastic Latches
Many of the parts are held in place with plastic
latches. The latches break easily; release them
carefully.
To remove such parts, press the hook end of the
latch away from the part to which it is latched.
Whenever servicing the machine, you
must perform as follows:
1. Check to verify that documents are not stored
in memory.
2. Be sure to remove the toner cartridge before
you disassemble parts.
3. Unplug the power cord.
4. Use a flat and clean surface.
5. Replace only with authorized components.
