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 feeder
● Feeder's rollers
•
When cleaning the machine, fi rst turn OFF the
main power switch, and disconnect the power cord.
Failure to observe these steps may result in a fi re or
electrical shock.
•
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 fi re.
IMPORTANT
•
When cleaning with a cloth, do not dampen it too
much, as this may damage the original or break the
machine.
•
Do not use alcohol, benzene, paint thinner, or other
solvents for cleaning. Doing so may result in damage to
the plastic parts.
NOTE
The feeder is an optional product.
Cleaning the Platen Glass and
Underside of the Feeder
If the platen glass or the underside of the feeder is dirty,
the original may not be scanned clearly, or the size of the
original may be detected incorrectly. Clean the platen
glass and the underside of the feeder by following the
