3.1 GENERAL INFORMATION

This chapter describes disassembly/assembly procedures to be used for replacing the main
assemblies of the EPL-5500.

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 photoconductor unit and toner cartridge.
If the photoconductor unit 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 upper unit until the main motor stops completely. Otherwise, the gears
may be damaged.
When transporting the printer, remove the photoconductor unit and toner cartridge
from
the printer.
When transporting the printer a long distance, pack up the printer using the original
packing material.
