Cleaning to prevent paper
jams
When you clean the inside of the machine,
pay attention to the following:
1
Turn off the machine’s power switch.
Unplug the telephone line cord first, and
then unplug the power cord from the
electrical socket. Open the back cover
of the machine.
2
Clean the registration roller and the
paper pick-up roller with a dry soft,
lint-free cloth to prevent paper jams.
WARNING
■ The fusing unit and the parts around it
are hot! Never touch the shaded areas
shown below.
■ Be careful not to inhale the toner.
CAUTION
■ When you clean parts inside the
machine, use a clean, dry soft, lint-free
cloth. Do not use Isopropyl alcohol.
■ If your clothes are smeared with toner,
wipe off the toner with a dry cloth.
Immediately wash your clothes in cold
water to avoid stains.
■ Never touch or clean the transfer roller
because print quality may be adversely
affected.
