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.

2.2.4.2 Imaging unit

1) Printing process overview

This mono printing system includes the LSU with a laser beams, a toner cartridge and transfer roller.
This machine uses single toner cartridge and dual laser beams for mono printing. The toner cartridge

consists of Drum unit and Development unit. The Drum unit has an OPC drum, cleaning blade.
The OPC drum is charged with a negative voltage by the scorotron 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 and electric filed.
The toners(real image) on the OPC drum are moved to the transfer media by the positive bias applied to the
transfer roller.

1. Charging the OPC drum: The scorotron gives the drum negative charges.

2. Laser exposure: Light produced by a laser diode irradiates the charged OPC through the lens and mirrors.

3. Development: This machine uses a dual-component development system . The magnetic roller carries negatively

charged toner to the latent image on the drum surface.

4. Transfer: The transfer rollers opposite the OPC drums transfer toner from the drums to the transfer media (e.g.
paper, OHP film, etc).

5. Cleaning for OPC drum: The cleaning blade removes remaining toners on the drum surface after image transfer

to the paper.

2.2.4.3 Fuser unit

It is consisted of a halogen lamp, heat roller, pressure roller, thermistor and thermostat. It sticks the toner on
a paper by heat and pressure to complete the printing job.

1) Thermostat

When a heat lamp is overheated, a Thermostat cuts off the main power to prevent over- heating.

- Thermostat Type : Non- Contact type THERMOSTAT

- Control Temperature : 170℃ ± 5℃

2) Thermistor

It is a temperatrue detecting sensor.

- Temperature Resistance : 7㏀ (180℃ )

3) 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 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, toner adheres to the surface of a
paper permanently.

5) Halogen Lamp

- Voltage 120 V : 115 ± 5 %

2.2.4.4 LSU (Laser Scanning Unit)

It is the core part of the LBP which switches from the video data received to the controller to the electrostatic
latent image on the OPC drum by controlling laser beam, exposing OPC drum, and turning principle of
polygon mirror. The OPC drum is turned with the paper feeding speed. The /HSYNC signal is created when
the laser beam from LSU reaches the end of the polygon mirror, and the signal is sent to the controller.
The controller detects the /HSYNC signal to adjust the vertical line of the image on paper. In other words,
after the /HSYNC signal is detected, the image data is sent to the LSU to adjust the left margin on paper.
The one side of the polygon mirror is one line for scanning.
