This chapter describes the disassembly/assembly procedures to be used for replacing the main
assemblies of the EPL-N2000.

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,
take the following precautions:
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).
Be sure to close the top cover when operating the printer. This printer uses an invisible
laser beam which could cause damage or loss of eyesight. Therefore never energize the
interlock switch to connect current with the top cover open.
Handle frame edges with care since this printer has a considerable amount of metal
materials.
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 printhead assembly.
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.
When transporting the printer, remove the Imaging cartridge.
When transporting the printer a long distance, pack it using the original packing
material.
