EPSON EPL-N1600

4.1 OVERVIEW

This chapter explains how to disassemble the printer and its various
mechanisms. Except where otherwise indicated, the reassembly
procedure is the reverse of the disassembly procedure.

4.1.1 Precautions

This section describes the precautions you must take to prevent
accidents during disassembly and reassembly work. Be sure to carry
out all work in accordance with the precautions and general instructions
provided in this manual.

The following three safety switches are provided to
protect against equipment breakdown or possible
injury. DO NOT MODIFY THESE SWITCHES:
<INTERLOCK SWITCH>
This safety switch goes OFF when the Cover Assy.
Exit opens, cutting the 24V power to the control
circuitry and the engine.
<5V INTERLOCK SWITCH>
This switch goes OFF when the Cover Assy. Exit is
opened, cutting the power to the laser-diode circuit.

Make sure to unplug the printer before beginning
disassembly.

Be aware that the fuser unit remains hot for some time
after the printer goes off. Allow the unit sufficient time
to cool down before you touch it.

Take care to avoid catching hands in movable parts
(rollers, fan, etc.).

Never touch conductive areas of the printer (the HPS
ASSY primary side, the chassis, or the high-voltage
components) while the printer is plugged in.

Never remove the cover of the ROS ASSY.

Be careful to avoid injury from frame edges and other
sharp or protruding areas of the printer.

Do not disassemble the Imaging Cartridge.

Keep Imaging Cartridges away from direct sunlight.

Do not disassemble the ROS ASSY.

Avoid touching IC elements with bare hands, so as to
prevent possible damage from electrostatic
discharge. If you need to touch these areas, wear
appropriate electrostatic protection gear
(electrostatic wrist band, etc.).

To ensure work efficiency and safety, use only the
tools specified in this manual.

Do not open the upper case until the main motor has
come to a complete stop.

Remove the Imaging Cartridge before transporting
the printer.

Before transporting the printer, pack it correctly into
its dedicated packaging.

The printer uses screws of many different types. Be
sure to note the correct location for each screw
before removing it. Inserting screws into the wrong
places may strip or damage the screw holes.
