3.1.1 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.

Static electricity can damage a PBA, always used approved anti-static precautions when
handling or storing a 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.

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 elec-
trical 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 cir-
cuit or get an electric shock. Take extra care when handling PBAs with moving parts fitted such as sen-
sors, motors or lamps as they may get hot.

screw is used and always ensure that when toothed washers are removed they are refitted in their orig-
inal positions.

ly; release them carefully.
