Routine Cleaning

If the original is not copied clearly, clean the following parts of the machine. For
high-quality printouts, we recommend cleaning these parts once or twice a month.
•
Platen glass
•
Underside of the platen cover
•
Feeder/Feeder's roller
WARNING
•
When cleaning the machine, first turn OFF the main power switch, and
disconnect the power cord. Failure to observe these steps may result in a fire or
electrical shock.
•
Do not use alcohol, benzene, paint thinner, or other solvents for cleaning. Doing
so may result in damage to the plastic parts.
•
Disconnect the power cord from the power outlet regularly, and clean the area
around the base of the power plug's metal pins and the power outlet with a dry
cloth to ensure that all dust and grime is removed. If the power cord is
connected for a long period of time in a damp, dusty, or smoky location, dust
can build up around the power plug and become damp. This may cause a short
circuit and result in a fire.

Platen Glass and Underside of the Feeder/Platen Cover

Clean the platen glass and the underside of the feeder/platen cover by following the
procedure below.
IMPORTANT
If the platen glass or the underside of the feeder/platen cover is dirty, the original may not
be scanned clearly, or the size of the original may be detected incorrectly.
NOTE
Cleaning the underside of the platen cover is necessary only if the platen cover is
attached.
