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 otherwise
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. Samsung recommend that this machine be disconnected from
the power source when such weather conditions are expected. Do not touch the machine or the power cord if it
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.

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 Samsung 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

Precautions
Samsung Electronics Service Manual

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 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 sufficient to
damage an ESD.
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.

3.7 FUSER AC POWER CONTROL
The Fuser(HEAT LAMP) gets heat from AC power. The AC 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/off with
taking signal from engine control part.
When the 'HEATERON' signal is turned on at engine,the LED of PC102 (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 off, the PC102 is off, the voltage is cut off at the gate of Triac, the Triac
becomes off, and then the heat lamp is turned off.
1) Triac feature : 12A, 600V SWITCHING
2) Phototriac Coupler (PC102)
- Turn OnIf Current : 15mA~50mA(Design : 16mA)

5.1 General Precautions on Disassembly
When you disassemble and reassemble components, 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 removing any component from the machine, note the cable routing that will be affected.
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 posi-
tion.
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.

• Description While Power turned on, the printer is not working in the printing mode.
Check and Cause Solution
1. Run Self-Test Mode : Turn the power on and pressing
“System Data List” by pressing Menu-Reports-System
Data.
2. Check if the PC and the printer is properly connected
and the toner cartridge installed.
3. Printing is not working in the Windows.
4. Check if the printer cable is directly connected to periph-
eral devices
1.Check the power of the printer and perform the Self-
Test. If the test printing works, that means no prob-
lems in the printer itself. If the test printing does not
work, that means bad functioning of the printer(not
because of software).
2. Replace the printer cable. If the problems not solved
even after the cable replaced, check the amount of
the remaining toner.
3. Check if the connection between PC and printer port
is proper. If you use windows, check if the printer dri-
ver in the controller is set up. If the printer driver is
properly set up, check in which program the printing
is not working. The best way to find out is to open the
memo pad to check the function of printing. If it is not
working in a certain program, adjust the setup the
program requires. Sometimes, the printout is normal
within the Windows basic programs, but it's not work-
ing in a particular program. In such case, install the
new driver again. If not working in the Windows basic
program, Check the setup of the port of CMOS is on
ECP. And check the address of IRQ 7 and 378

6.4.2 The printer is not working (2)
• Description After receiving the printing order, no response at all or the low speed of printing
occurs due to wrong setup of the environment rather than malfunction of the printer itself.
Check and Cause Solution
1. Secure more space of the hard disk.
2. Printing error occurs even if there is enough space in
the hard disk.
3. Check the parallel-port-related items in the CMOS
Setup.
4. Reboot the system to print.
1. Not working with the message 'insufficient printer
memory' means hard disk space problem rather than
the RAM problem. In this case, provide more space
for the hard disk. Secure more space using the disk
utilities program.
2. The connection of the cable and printer port is not
proper. Check if the connection is properly done and
if the parallel port in CMOS is rightly set up.
3. As a printer port, Select ECP or SPP among
SPP(Normal), ECP, and EPP modes(increase print-
ing speed) SPP normal mode support 8-bit data
transfer, while ECP Mode transfer the 12-bit data.
4. If the regular font is not printing, the cable or the
printer driver may be defective.
Turn the PC and printer off, and reboot the system
to print again. If not solved, double-click the printer in
my computer If the regular fonts are not printed this
time again. the cable must be defective so replace
the cable with new one.

6.9 Toner Cartridge Service
Only toner cartridges supplied by Samsung should be used. Printing defects or set damage caused by the use of
non-approved toner cartridges or un-licensed toner refills are not covered by the guarantee.
6.9.1 Precautions on Safe-keeping of Toner Cartridge
Excessive exposure to direct light for more than a few minutes may cause damage to the cartridge.
6.9.2 Service for the Life of Toner Cartridge
If the printed image is light due to the toner supply becoming low you can temporarily improve the print quality by
redistributing the toner (Shake the toner cartridge), however you should replace the toner cartridge to solve the problem
permanently.
6.9.2.1 Redistributing Toner
When the toner cartridge is near the end of its life, white streaks or light print occurs. The LCD displays the warning mes-
sage, “Toner Low.” You can temporarily reestablish the print quality by redistributing the remaining toner in the cartridge.

- Explanation: The toner cartridge is empty
- Solution: Replace the cartridge.
6.9.4.3 Drum Warning
- Explanation: This message appears when the OPC drum is nearing the end of its life (14,000pages). This means
that the life of the mechanical parts in the cartridge has expired (this is not an indication of toner remaining).
- Solution: After printing about 15,000 pages, in a worst case scenario, the waste toner collector might overflow and it
may cause the system to fail. Also after 15,000 pages the OPC drum surface will be becoming worn and print quality
will degrade, print images will become misty. It is therefore necessary to replace the cartridge even though there may
be toner left in it.
When this message occurs there are approximately 1,000 pages left.

2. Check that the PC and the printer are properly
connected and that the toner cartridge installed
correctly.
3. Printing is not working in the Windows.
4. Check that the printer cable is directly connected to the
printer.
1. If the test print works that means there are no
problems in the printer itself. If the test printing does
not work that means the printer is faulty and the
problem is not due to computer software or driver
settings.
2. Replace the printer cable. If the problem is not
solved even after the cable is replaced, check the
amount of the remaining toner. (refer to Toner
Cartridge Service 7-6, Page 7-25)
3. Check that the connection between PC and printer
port are correcct. If you use windows, check that the
printer driver in the controller is set up correctly set
up, the correct port is selected and ‘Use On-line’is
selected in the driver. If the printer driver is properly
set up try printing a test page from the driver proper-
ties. Check in which program printing is not working.
Try opening ‘Note Pad’and printing. If the printer is
not working in a certain program, adjust the setup
within that program.
Sometimes, the printout is normal within the
Windows basic programs, but it's not working in a
particular program. In this case, uninstall and re-
install the new driver. If the printer is not working in
the Windows basic programs and you are printing
using the parallel port check the port setting in
CMOS is on ECP and that the address is IRQ 7
and 378 (for parallel port 1). Try using USB instead
of parallel – or vice versa.
4. If you have other devices that need to share the
printer port try temporarily disconnecting these
devices and perhaps even uninstalling their drivers)
to ensure the printer works by itself. If you are using
a USB hub try connecting directly to the back of the
PC instead.

1. Ensure you have sufficient free hard disk space for the
temporary work files created during printing.
2. Printing error occurs even if there is enough space in
the hard disk.
3. Check the parallel-port-related items in the CMOS
Setup.
4. Reboot the system to print.
1. Not working with the message 'insufficient printer
memory' means there is a hard disk space problem
rather than a printer RAM problem. In this case pro-
vide more space on the hard disk. Secure more
space using the disk utilities program.
2. The connection of the cable and printer port is not
correct. Check that the cable is properly connected
and if you are using the parallel port check that the
port settings in CMOS is correct.
3. For the printer port, Select ECP. SPP and normal
normal modes support 8-bit data transfer, while
ECP Mode supports 12-bit data transfer.
4. If the regular font is not printing, the cable or the
printer driver may be defective.
Turn the PC and printer off, and reboot the system
to print again. If not solved, double-click the printer
in my computer If the regular fonts are not printed
this time again. the cable must be defective so

the printer. 1. Check that the LAN cable is connected to the printers. If an IP
address is assigned to the computer and printer ensure that the
Ping command can see the printer.
If an IP address is not allocated to the printer or it is in a different
LAN segment then ensure that either IPX/SPX or DLC/LLC pro-
tocols are enabled on the computer.
2. Print the network configuration. If the TCP/IP or Network proto-
cols are disabled in the printer either use the front panel to re-
enable them or ensure that DLC/LLC protocol is installed in the
computer.
3. In SyncThru use the Settings / Protocol Selection menu option to
select either TCP/IP or IPX protocols and then use the
View/Refresh option to scan the network again.
4. Ensure that the network cable and wall socket are functioning
correctly.
5. Ensure that the version of SyncThru is the same as or newer
than the version supplied with the printer.
6. Ensure that there is no router between the printer and the
computer as SyncThru will not work through a router.
7. Ensure there are no Switch or Router VLAN or Access Control
Lists which are blocking communication between the printer and
the computer.
Note Windows XP does not support DLC/LLC protocols.
The printer does not print via a
network connection. 1. Connect the printer using a Parallel or USB cable and ensure
that the computer can print. If not check that the printer drivers
are installed correctly
2. If the printer can print via a local connection check Printer
Properties / Ports and ensure that a TCP/Ip port has been allo-
cated to the printer.
