This chapter describes the disassembly/assembly procedures to be used for replacing the main
assemblies of the EPL-N1200.

3.1.1 Precautions for Disassembly/Assembly

Follow the precautions below when disassembling/assembling the printer.
Disconnect the power cord before disassembling/assembling the printer.
Be sure to handle the fusing unit carefully, because the unit remains hot for a
while after the
printer stops printing.
If it is necessary to plug in the power cord and operate the printer after
disassembling it,
please be careful of the following:
1. Keep your hands and clothing well away from operating or rotating parts (such
as rollers,
fan motors, etc.).
2. Never touch electric terminals or high-voltage components (such as the charger
and the high
voltage unit).
Do not disassemble the imaging cartridge.
If the imaging cartridge is removed from the printer, do not place it in direct
sunlight.
Do not disassemble the optical unit.
Never turn power on if the optical unit is not installed.
To prevent damage to ICs from static electricity, do not touch the ICs on the
circuit board or
the terminals of peripheral electrical components with your hands.
Use only the recommended tools to ensure safe and efficient maintenance work.
Inappropriate tools may damage the machine.
Never open the top cover until the main motor stops completely. Otherwise, the
gears may
be damaged.
When transporting the printer, remove the imaging cartridge from the printer.
When transporting the printer a long distance, pack up the printer using the
original packing
material.
