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.

Cassette
•Feeding Method : Cassette Type
•Feeding Standard : Center Loading
•Feeding Capacity : Cassette 150 Sheets(75g/ , 20lb Pa per Standard)
•No Manual Feeder
•Paper Detecting Sensor : Photo Sensor (Empty, Registration, Exit)
•Paper Size Sensor : None
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.

2nd Transfer Ass’y
•The life span: Print over 100,000 sheets (in 15~30 )
•Specification: Similar to CLP-300 Series
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 Teflon, 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 Teflon. When a paper passes between a heat roller and a pressure roller, toner adheres to the surface of a paper permanently.

•Conductive Roller charging
•Applied voltage : -1.1kV
•Charge acceptance : -520V
•OPC coating thickness : 21um
•OPC diameter : Φ60mm
•Eraser system
1.Organic Photoconductor is charged to uniform voltage by conductive roll charging method
2.No ozone is produced because corona is not used
3.Charger roll is cleaned with cleaning roll
4.Toner remained on OPC after T1 process is cleaned by cleaning blade and retrieved into waste toner box by auger and belt driving mechanism
Exposing
•One polygon motor ( 6 facet )
•Single beam LD (1ea)
•LD wavelength : 785nm
•Polygon motor rpm : 29685
•LSU energy : 0.25uJ/cm^2
•OPC exposed potential : -50V
1.Exposing is implemented by laser striking on to OPC with uniform potential
2.Laser beam is modulated according to image to be printed that is from PC
3.Latent Image is formed on OPC, which is developed with toner
Developing
•Non-magnetic, mono component
•Non-contact development
•Developing bias : DC + AC
•AC peak to peak : 1.5 ~ 2.0kV
•Roller diameter : Φ10mm
•Process speed ratio : 1.2 (OPC=1.0)
•Color order : Y -> M -> C -> K
1.Only latent image formed by exposing process is developed with toner
2.AC + DC Voltage is being used to develop toner into latent image on OPC because non-contact developing method is adopted
3.Y, M, C, and K Images are sequentially developed onto OPC and transferred onto Intermediate Transfer Belt (hereafter ITB) to form a color image on ITB
4.Toner Bottles are used to supply toner into developer compartment
5.Toner level is being sensed to control toner supply from toner bottle to developer
