5) Do not install the printer on a sloping or unstable surface. After installation, double check that the printer is stable.

1. 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.

- This roller picks up the paper from the tray.
• Forward roller (Tray 1,2,3,4 and MP Tray)
- This roller is placed against the reverse roller. It transports the paper from the pick up roller to feed roller.
• Reverse roller (Tray 1,2,3,4 and MP Tray)
- This roller is placed against the forward roller and transports only one sheet to the feed roller. When two sheets of
paper or more are transported from the pick up roller, the load of the torque limiter of the reverse roller is heavier
than the frictional force between the sheets. As a result, the reverse roller is stopped and the lower paper does
not advance any further.
• Feed roller
- This roller transports the paper sent from the forward/reverse roller to the registration roller.
• Registration roller
- This roller aligns the leading edge of the paper and transports the paper to the transfer roller Assy.
• Registration sensor
- This sensor detects that the leading edge of the paper is arrived to the registration roller and the tail edge passed
by the registration roller.
• Exit Sensor

2.5. Image Creation
2.5.1. Printing process overview
This machine uses a toner cartridge, transfer roller, and LSU for mono printing.
The toner cartridge as integrated type consists of the toner bottle, drum unit and development unit. The drum unit
consists of an OPC drum, charge roller, cleaning roller, and cleaning blade. The development unit consists of the deve.
roller, supply roller, Dr.blade, and agitator.
The OPC drum is charged with a negative voltage by the charge roller and is exposed by the light from the LSU (Laser
Scanning unit).
The light produced by a laser creates a latent image by discharging on the surface of the OPC drum. The negatively charged
toners are attracted to the latent image due to the electric field. The toner(real image) on the OPC drum are moved to the
paper by the positive bias applied to the transfer roller.
1) OPC drum charge : The charge roller gives the OPC drum a negative charge.
2) Laser exposure : Light produced by a laser diode(LD) hits the charged OPC drum through the lens and mirrors. The
machine controls the laser beam on/off for the latent image.
3) Development : The developing roller carries the negatively charged toner to the latent image on the OPC drum surface.
4) Transfer : The negatively charged toner is transferred to the paper by transfer voltage.
5) Cleaning for OPC drum : The cleaning blade remove remaining toner on the OPC drum surface after image transfer
to the paper.

2.5.2. Toner Cartridge
The toner cartridge as integrated type consists of the toner bottle, drum unit and development unit.
The OPC drum diameter is 24.03 mm (circumference : about 75.4mm). / Deve roller diameter is 14.07mm (circumference :
about 37mm).
The toner cartridge uses non magnetic 1 element shatter type toner, the remaining toner is detected by CRUM as Dot
Count method.
After the image is moved to transfer roller, the remaining toner on the OPC drum is removed by the cleaning blade.
The CRUM chip in toner cartridge stores information like a serial number, count.
Development
The toner is supplied to the Agitator-Toner 1 by the Agitator-Toner2 and moves from the supply roller to deve roller.
After the supplied toner on deve roller exits from the Dr.blade, it forms a developer brush. Then toner is attracted to the
surface of the OPC drum only in areas the corresponds to the image area.

2.6. Fuser unit
It is consisted of a halogen lamp, heat roller, pressure roller, thermistor and thermostat. It fuses the toner on a paper by
heat and pressure to complete the printing job.
Thermistor
Thermostat
Heat Roller
Halogen Lamp
Pressure Roller2
Pressure Roller
1) Thermostat
When a heat lamp is overheated, a Thermostat cuts off the main power to prevent overheating.
• Thermostat Type : Non- Contact type
• Control Temperature : 190℃ ± 5℃
2) Thermistor
It is a temperature detecting sensor.
• Temperature Resistance : 7 KΩ(180℃ )
• Rated B-value R25/85 3370K±3% (The Rated B-value is calculated from the zero-power resistance measured
at 25℃ and 85℃)
3) Heat roller
The heat roller transfers the heat from the lamp to apply heat on to the paper.
The surface of a heat roller is coated with Teflon, so toner does not stick to the surface.
4) Pressure roller
A pressure roller mounted under a heat roller is made of a silicon resin, and the surface also is coated with Teflon.
When a paper passes between a heat roller and a pressure roller, the toner fuses to the surface of a paper permanently
through this combination of heat and pressure.
