4.1 Overview
This section provides warnings and cautions about disassembling and
assembling the printer, and information about tools and screws. It also
describes how to check the printer after you repair it to make sure it is
operating properly.
4.1.1 Precautions
Follow the precautions below when disassembling or assembling the
printer.
WARNING
Before disassembling, assembling, or adjusting
the printer, disconnect the power supply cable
from the AC power socket. Failure to do so can
cause physical injury.
The power switch is wired in the secondary
circuitry of the power supply board. Therefore,
the power supply’s primary circuitry remains
live even after the printer is turned off.
Never touch primary parts of the power supply
unit (including the heat sink) while the printer is
plugged in.
CAUTION
To maintain efficient printer operation:
Use only recommended tools for repair or
maintenance work.
Use only recommended lubricants and
adhesives. (See Chapter 6.)
Adjust the printer only as described in this
manual.
