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 eld 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 classied as “anti-static”
can generate electrical charges sufcient to damage ESDs.
5. Do not use Freon-propelled chemicals. When sprayed, these can generate electrical charges sufcient 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 oor, can generate static electricity sufcient to damage an ESD.

LSU(Laser Scan Unit)
The LSU unit is controlled by video controller. It scans the video data received from video controller with
laser beam by using the rotation principle of the polygon mirror to create the latent image on the OPC drum. It is the core part of LBP. The OPC drum rotates as the same speed as the paper feeding speed. It creates the /HSYNC signal and sends it to the engine when the laser beam of the LSU reaches the end of the polygon mirror, and the engine detects the /HSYNC signal to arrange the vertical line of the image on the paper. After detecting the /HSYNC signal, the image data is sent to the LSU to arrange the its margin on the paper.
• Consisted of LD(Laser Diode) and Polygon Motor Control.
Error Phenomenon
Polygon Motor Error The Rotation of Polygon Motor can not reach stable
Hsync Error Though the rotation of Polygon Motor reach stable, the signal of Hsync is
not occurred

2nd Transfer Ass’y
• The life span: Print over 100,000 sheets (in 15~30 )
Fuser Ass’y
This unit consists of Heat Roller, a Thermostat and a Thermistor. It melts and fuses the toner, transferred
by the transfer roller onto the paper, by applying pressure and high temperature to complete printing job.
* Heat Lamp : Kunckle Type * Fusing system : 3-Roll Fusing type
- Heat roller : Pipe type (Lamp inside)
- Pressure roller
- Pressure roller Shaft * Thermistor - Temperature-Measuring Device * Thermostat - Critical Temperature-Detecting Device * The life span – 100k(black)/color(25k)
Thermostat
When a heat lamp is overheated, a Thermostat cuts off the main power to prevent over-heating.
- Non-Cotact type Thermostat
Heat roller
The heat roller transfers the heat from the lamp to apply a heat on the paper. The surface of a heat
roller is coated with Teon, so toner does not stick to the surface.
Pressure roller
A pressure roller mounted under a heat roller is made of a silicon resin, and the surface also is coated
with Teon. When a paper passes between a heat roller and a pressure roller, toner adheres to the surface
of a paper permanently.
