Precautions
1.2 Caution for safety
1.2.1 Precaution related noxious material
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
4.2 System Layout
4.2.1 Feeding section
There is the universal cassette, which automatically loads paper and the manual feeder, which supplies paper one by one. The cassette has the friction pad which separates paper one by one, and it has a sensor, which functions to check the existence of loaded paper.
- Feeding Method: Universal Cassette Type - Feeding Standard: Center Loading
- Feeding Capacity: Cassette-250 sheets (75g/m2, 20lb paper standard) Manual 1 sheet (Paper, OHP, Envelop, etc.)
- Paper detecting sensor: Photo sensor - Paper size sensor: None
4.2.2 Transfer Ass’y
It consists of the PTL (pre-transfer lamp) and the Transfer Roller. The PTL sends a light to the OPC drum, drops the current on the drum surface and improves the transfer efficiency.
The transfer roller transfers toner from the OPC drum surface to the paper. - The life span: Print over 60,000 sheets (in 15~30°C)
4.2.3 Driver Ass’y
- Gear driven power unit. By driving the motor, it supplies power to the feeding unit, the fusing unit, and the distributing unit.
4.2.4 Fixing Part(Fuser)
-The fuser consists of the Heat Lamp, Heat Roller, Pressure Roller, Thermistor, and Thermostat. It adheres toner to the paper with pressure and a heat to complete the printing job.
4.2.4.1 Temperature-Intercepting Device (Thermostat)
The thermostat is the temperature-intercepting device, which cuts off the power for preventing an overheating or a fire when the heat lamp or the heat coil of the heat roller is overheated.
4.2.4.2 Temperature Detecting Sensor (Thermistor)
The Thermistor detects the surface temperature of the heat roller, and it maintains the regular temperature of the heat roller by responding to the information of the temperature.
4.2.4.3 Heat Roller
The heat roller transfers the temperature from the heat lamp to the surface to heat the paper which passes the surface. The melted toner cannot stain the heat roller coated with Teflon.
4.2.4.4 Pressure roller
The pressure roller mounted right under the heat roller is made of the silicon resin, and the surface of the roller is coated with Teflon to fuse the toner on the paper when paper passes between the heat roller and the pressure roller.

SUMMARY OF PRODUCT
4.2.6 LSU (Laser Scanner Unit)
The LSU unit is controlled by the video controller. It scans the video data received from video controller with laser beam by using the rotation principal 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 /HS YNC signal and sends it to the engine when the laser bean of the LSU reaches the end of the polygon mirror, and the engine detects the /HS YNC signal to arrange the vertical line of the image on the paper. After detecting the /HS YNC signal, the image data is sent to the LSU to arrange the its left margin on the paper.
The one side of the polygon mirror is one line for scanning.
