4.1 OVERVIEW
This section describes various points to note when disassembling and
assembling the printer.
4.1.1 Precaution
Following the precautions below for disassembly or assembly.
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. Therefore, the printer’s primary
circuitry remains live even after the power
switch is turned off.

unit (including the heat sink) while the power
supply cable is connected to the AC power
socket.
