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/platen cover
• Feeder scanning area
• White plate, 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, as
this may result in plastic parts becoming deformed.
CAUTION
• Unplug the power plug from the outlet at least once a year, and clean the plug’s
metal pins and the area surrounding them to ensure all dust is removed. If dust
accumulates in this area, it may result in a fire.
• Do not dampen the cloth too much, as this may damage the original or damage
the machine.
• 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.
