Service Manual
6.1.1 Precautions when assembling and disassembling
* Use only approved Samsung spare parts. Ensure that part number, product name, any voltage, current or
temperature rating are correct. Failure to do so could result in damage to the machine, circuit overload,
fire or electric shock.
* Do not make any unauthorized changes or additions to the printer, these could cause the printer to mal-
function and create electric shock or fire hazards.
* Take care when dismantling the unit to note where each screw goes. There are 19 different screws. Use of
the wrong screw could lead to system failure, short circuit or electric shock.
* Do not disassemble the LSU unit. Once it is disassembled dust is admitted to the mirror chamber and will
seriously degrade print quality. There are no serviceable parts inside.
* Regularly check the condition of the power cord, plug and socket. Bad contacts could lead to overheating
and firfe. Damaged cables could lead to electric shock or unit malfunction.
6.1.2 Preautions when handling PBA
Static electricity can damage a PBA, always used approved anti-static precautions when
handling or storing a PBA.
>> Precautions when moving and storing PBA
1. Please keep PBA in a conductive case, anti-static bag, or wrapped in aluminum foil.
2. Do not store a PBA where it is exposed to direct sunlight.
>> Precautions when replacing PBA
1. Disconnect power connectors first, before disconnecting other cables
2. Do not touch any soldered connections, connector terminals or other electronic parts when handling
insulated parts.
>> Precautions when checking PBA
1. Before touching a PBA, please touch other grounded areas of the chassis to discharge any static electrical charge on the body.
2. Take care not to touch the PBA with your bare hands or metal objects as you could create a short circuit or get an electric shock. Take extra care when handling PBAs with moving parts fitted such as sensors, motors or lamps as they may get hot.
3. Take care when fitting, or removing, screws. Look out for hidden screws. Always ensure that the correct
screw is used and always ensure that when toothed washers are removed they are refitted in their original positions.
6.1.3 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.

6.2 Parts for Maintenance and Repair
6.2.1 Replacement interval for parts with a limited life
Some of the parts in this printer have a limited life, shorter than that of the whole machine. These parts
must be replaced periodically.
The table below shows the interval at which these parts should be replaced.
The table shows the life of each part, and is measured when using A4 paper. When servicing a machine
always check the status of these parts using the control panel and ensure that parts are replaced at the
appropriate times otherwise a general degradation in print quality will occur.
* Page: Counted value based on sides of paper printed (Duplex = 2 pages).
* Image: Counted value based on printed monochrome images.
* When printing a color section 1 page = 4 images. (i.e. each side is made up of 4 color images)
The life span of each of these parts is stored in memory. The amount of each 'life' used can be checked at
any time using the control panel.
When a part is replaced it is necessary to reset the 'life used' that is stored in memory.
* How to initialize a the value of part's life span:
From the control panel, select the following items in order:

6.2.2 Printer Cleaning
A printer should be regularly cleaned, especially if it is used in a dusty environment. This will ensure that
print quality remains high and failure due to contamination of printing services is less likely to occur.
* Clean the printer with a soft, lint free, cloth dipped in a "Recommended cleaner"
"Recommended cleaner" can be purchased from our service center. (where available)
* Do not touch the transfer roller when cleaning the inside of the printer. Grease and oils from the
skin will contaminate the surface and reduce print quality.
* Do not touch transfer roller when cleaning inside of machine. If transfer roller gets dirty, printing
quality could be low.
* Please refer to the User Manual for cleaning instructions.

1) Disassembly of the LSU unit
There are no serviceable parts inside the
LSU. Alignment of the mirrors is critical.
Opening the LSU will allow dust into the
laser and significantly reduce print quality.
It is very dangerous to operate or service
a machine with the LSU open or system
interlocks disabled. Exposure to laser
radiation can cause blindness.
2) Disassembly of the ITB unit
Do not disassemble the ITB. The alignment of the home sensor is critical and is
set up in the factory on a special jig.
Incorrect re-assembly will cause print
quality degradation.
3) Care of the OPC unit
If an OPC unit is exposed to direct sunlight for a long time the parameters and
response of the electrostatic surface are
changed causing image transfer and print
quality issues. Also there is no protective
shutter on the OPC drum to prevent
scratching Please take extra care to
ensure the OPC drum is protected from
sunlight and physical contact when servicing the machine.
4) Care of the Toner cartridge
Toner cartridges contain an extremely fine
powder. 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. Take care not to spill toner spillages should be cleaned with a
vacume cleaner and washed in could
water (hot water sets the toner). Do not
touch the developer roller surface as contamination will reduce print quality. Take
care not to damage the roller's surface
when installing or removing a toner cartridge.
5) Disassembly of DEVE drive ass'y
and the main drive ass'y
The alignment of the drive mechanism is
critical and it has been set up in factory
using a jig and a driving gear. It is adjusted for the best gearing alignment. If the
motor is disassembled alignment would
not be maintained and this could cause
operational noise and image problems:
image alignment and toner distribution
may be affected.
6) Disassembly of terminal parts
Do not adjust the variable resistors on the
PBA. They have been already adjusted in
the factory.
7) Disassembly of the fuser unit
- The fuser melts toner onto the paper at
a high temperature: therefore, you need
to take special care not to get burned by
a hot fuser. When removing the fuser
from a set that has recently been operating you need to take extra care.
- Do not touch an AC line (Copper contact) on a main frame even after removing the fuser.
