6.1 Overview

This section gives information necessary for maintaining the printer in its optimum
condition.
In maintenance and checks, never fail to observe the following precautions.
To ensure the safety during servicing (to prevent electric shocks
W A R N I N G
or damage to the circuit), before servicing, be sure to unplug
the power cable from the AC inlet of the printer, unless power
to the printer is required for, say, printing or operation check.
The FUSER ASSY and other high-temperature parts remain at
hazardous temperature for a certain period of time even after
stop of operation and turning off of the power. To prevent
suffering a burn, be sure to wait after power turning off until
the temperature of the parts cool down to a safe level, and then
start working on the printer.
Always wear gloves for maintenance and checks to avoid injury
from sharp metal edges.
Take great care not to expose yourself to the laser beam;
otherwise, you could suffer injury (blindness).
When you perform maintenance or service of the laser printer,
never open any cover on which a warning label about laser
beam is affixed.
Understand how the laser beam functions and take maximum
precautions not to injure yourself or anyone around you.
To avoid dust explosion or ignition, never bring any
consumables close to flame or throw them into fire.
Do not use alcohol, paint thinner, or any other such solvents.
C A U T I O N
Do not clean the roller surface of the Transfer Roller (BTR
Assy). If the roller is particularly dirty, try printing some sheets
to remove the dirt, or take out the Transfer Roller Unit and
blow the dirt off using a compressed air gun.
