should be avoided, wash any splashes from eyes or skin immediately and contact your doctor . If the liquid gets into  
the mouth or is swallowed see a doctor immediately.  
(2) Please keep toner cartridges away from children. The toner powder contained in the toner cartridge may be harmful  
and if swallowed you should contact a doctor.  
1.2.2 Electric Shock and Fire Safety Precautions  
Failure to follow the following instructions could cause electric shock or potentially cause a fire.  
(1) Use only the correct voltage, failure to do so could damage the printer and potentially cause a fire or electric  
shock.  
(2) Use only the power cable supplied with the printer . Use of an incorrectly specified cable could cause the cable  
to overheat and potentially cause a fire.  
(3) Do not overload the power socket, this could lead to overheating of the cables inside the wall and could lead to  
a fire.  
(4) Do not allow water or other liquids to spill into the printer , this can cause electric shock. Do not allow paper  
clips, pins or other foreign objects to fall into the printer these could cause a short circuit leading to an electric  
shock or fire hazard..  
(5) Never touch the plugs on either end of the power cable with wet hands, this can cause electric shock. When  
servicing the printer remove the power plug from the wall socket.  
(6) Use caution when inserting or removing the power connector . The power connector must be inserted com -  
pletely otherwise a poor contact could cause overheating possibly leading to a fire. When removing the power  
connector grip it firmly and pull.  
(7) Take care of the power cable. Do not allow it to become twisted, bent sharply round corners or other wise  
damaged. Do not place objects on top of the power cable. If the power cable is damaged it could overheat and  
cause a fire or exposed cables could cause an electric shock. Replace a damaged power cable immediately ,  
do not reuse or repair the damaged cable. Some chemicals can attack the coating on the power cable,  
weakening the cover or exposing cables causing fire and shock risks.  
(8) Ensure that the power sockets and plugs are not cracked or broken in any way . Any such defects should be  
repaired immediately. Take care not to cut or damage the power cable or plugs when moving the machine.  
(9) Use caution during thunder or lightening storms. Dell recommends that this machine be disconnected from

is still connected to the wall socket in these weather conditions.  
(10) Avoid damp or dusty areas, install the printer in a clean well ventilated location. Do not position the machine  
near a humidifier. Damp and dust build up inside the machine can lead to overheating and cause a fire.  
(11) Do not position the printer in direct sunlight. This will cause the temperature inside the printer to rise possibly  
leading to the printer failing to work properly and in extreme conditions could lead to a fire.  
(12) Do not insert any metal objects into the machine through the ventilator fan or other part of the casing, it could  
make contact with a high voltage conductor inside the machine and cause an electric shock.

Precautions  
1.2.3 Handling Precautions  
The following instructions are for your own personal safety, to avoid injury and so as not to damage the printer  
(1) Ensure the printer is installed on a level surface, capable of supporting its weight. Failure to do so could cause  
the printer to tip or fall.  
(2) The printer contains many rollers, gears and fans. Take great care to ensure that you do not catch your fingers,  
hair or clothing in any of these rotating devices.  
(3) Do not place any small metal objects, containers of water , chemicals or other liquids close to the printer which if  
spilled could get into the machine and cause damage or a shock or fire hazard.  
(4) Do not install the machine in areas with high dust or moisture levels, beside on open window or close to a  
humidifier or heater. Damage could be caused to the printer in such areas.  
(5) Do not place candles, burning cigarettes, etc on the printer , These could cause a fire.  
1.2.4 Assembly / Disassembly Precautions  
Replace parts carefully, always use Dell parts. Take care to note the exact location of parts and also  
cable routing before dismantling any part of the machine. Ensure all parts and cables are replaced correctly .  
Please carry out the following procedures before dismantling the printer or replacing any parts.  
(1) Check the contents of the machine memory and make a note of any user settings. These will be erased if the  
mainboard or network card is replaced.  
(2) Ensure that power is disconnected before servicing or replacing any electrical parts.  
(3) Disconnect printer interface cables and power cables.  
(4) Only use approved spare parts. Ensure that part number , product name, any voltage, current or temperature  
rating are correct.  
(5) When removing or re-fitting any parts do not use excessive force, especially when fitting screws into plastic.  
(6) Take care not to drop any small parts into the machine.  
(7) Handling of the OPC Drum  
- The OPC Drum can be irreparably damaged if it exposed to light.  
Take care not to expose the OPC Drum either to direct sunlight or to fluorescent or incandescent room  
lighting. Exposure for as little as 5 mins can damage the surface’ s photoconductive properties and will result  
in print quality degradation. Take extra care when servicing the printer. Remove the OPC Drum and store it in  
a black bag or other lightproof container. Take care when working with the covers(especially the top cover)  
open as light is admitted to the OPC area and can damage the OPC Drum.  
- Take care not to scratch the green surface of OPC Drum Unit.  
If the green surface of the Drum Cartridge is scratched or touched the print quality will be compromised.

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 of f any  
electrostatic charge on your body by touching a known earth ground. Alternatively, employ a commercially avail -  
able 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 assem -  
bly.  
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 dam-  
age 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 compa -  
rable conductive material.  
7. Immediately before removing the protective shorting material from the leads of a replacement ESD, touch the pro-  
tective 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 com-  
pletely 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 suf ficient to  
damage an ESD.  
1.4 Super Capacitor or Lithium Battery Precautions  
1. Exercise caution when replacing a super capacitor or Lithium battery . There could be a danger of explosion and  
subsequent operator injury and/or equipment damage if incorrectly installed.  
2. Be sure to replace the battery with the same or equivalent type recommended by the manufacturer.  
3. Super capacitor or Lithium batteries contain toxic substances and should not be opened, crushed, or burned for  
disposal.  
4. Dispose of used batteries according to the manufacture’ s instructions.

FUSER AC POWER CONTROL  
Fuser(HEAT LAMP) gets heat from AC power. The AV power controls the switch with the Triac, a semiconductor switch.  
The ON/OFF control is operated when the gate of the Triac is turned on/off by Phototriac (insulting part).  
In other words, the AC control part is passive circuit, so it turns the heater on/of f with taking signal from engine control  
part.  
When the HEATER ON signal is turned on at engine, the LED of PC501 (Photo Triac) takes the voltage and flashes.  
From the flashing light, the Triac part (light receiving part) takes the voltage, and the voltage is supplied to the gate of  
Triac and flows into the Triac. As a result, the AC current flows in the heat lamp, and heat is occurred.  
On the other hand, when the signal is of f, the PC501 is off, the voltage is cut off at the gate of Triac, the Triac becomes  
off, and then the heat lamp is turned of f.

4.1.10 Toner Cartridge  
In the toner cartridge, the OPC unit and the developer unit are in a body .  
The OPC unit has OPC drum and charging roller, and the developer unit has toner, toner cartridge, supply roller, devel-  
oping roller, and the blade.  
4.1.11 LSU (Laser Scanner 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 sig -  
nal 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 .  
The one side of the polygon mirror is one line for scanning.  
4.1.12 Fixing Part (FUSER)  
The fuser is consisted of the Heat Lamp, Heat Roller , Pressure Roller, Thermistor and Thermostat.  
It adheres the toner to the paper with pressure and a heat to complete the printing job.  
4.1.13 TRANSFER Ass’y  
It is consisted of PTL (pre-transfer lamp) and Transfer Roller. The PTL sends a light to the OPC drum, makes the current  
on the drum surface to low, and improve the transfer efficiency.  
The transfer roller delivers the toner of the OPC drum to the paper .  
4.1.14 Driver Ass’y

Precautions  
5. Disassembly and Reassembly  
5.1 General Precautions on Disassembly  
5
When you disassemble and reassemble compo-  
nents, you must use extreme caution. The close  
proximity of cables to moving parts makes proper  
routing a must.  
If components are removed, any cables disturbed  
by the procedure must be restored as close as  
possible to their original positions. Before remov-  
ing any component from the machine, note the  
cable routing that will be affected.  
Releasing Plastic Latches  
Many of the parts are held in place with plastic  
latches. The latches break easily; release them  
carefully.  
To remove such parts, press the hook end of the  
latch away from the part to which it is latched.  
Whenever servicing the machine, you  
must perform as follows:  
1. Check to verify that documents are not stored  
in memory.  
2. Be sure to remove the toner cartridge before  
you disassemble parts.  
3. Unplug the power cord.  
4. Use a flat and clean surface.  
5. Replace only with authorized components.  
6. Do not force plastic-material components.  
7. Make sure all components are in their proper  
position.
