W A R N I N G
„
Disconnect the power cable before disassembling or assembling
the printer. If you need to work on the printer with power
applied, strictly follow the instructions in this manual.
„
Always wear gloves for disassembly and reassembly to avoid
injury from sharp metal edges.
„
To protect sensitive microprocessors and circuitry, use static
discharge equipment, such as anti-static wrist straps, when
accessing internal components.
„
Do not expose yourself to the laser beam to prevent injury
(blindness).
„
When you perform maintenance or service of the laser printer,
never open any cover on which a warning label about laser
beam has been affixed.
„
Understand how the laser beam functions and take maximum
precautions not to injure yourself or anyone around you. When
working on the FUSER ASSY or nearby parts, be sure to wait
until the temperature of the parts cools down to a safe level.
Wait at least 40 minutes before you start working on the printer.
„
To avoid dust explosion or ignition, never bring any
consumables close to flame or throw them into fire.
„
Take great care not to put developer or toner contained in the
consumables into your mouth or eye or not to inhale it.
„
Take due care that no one around you put developer or toner
into the mouth or eye or inhale it. Spread a sheet of paper inside
and around the printer to prevent soiling.
„
When developer or oil stuck to your skin or clothes, wipe it off
with a dry cloth carefully and wash it away with water
completely.
