Cleaning the Touch Screen
This section describes how to clean the touch screen of the machine.
1
Wipe the LCD only with a soft cloth moistened
with neutral detergent or alcohol.
Note • Do not apply too much neutral detergent or
alcohol. Squeeze out excess moisture before
you wipe the LCD if the fluid drips.
• Do not use volatile solvent such as benzene
and paint thinner or insect killer. Doing so
might cause discolored, deformed, or cracked
parts.
• Wipe the panel softly, otherwise, the parts
might be damaged.
Cleaning Document Cover and Document Glass
If the document cover and document glass become soiled, smudges may appear on copies,
faxes, or scanned documents and the machine may not properly detect document sizes.
To ensure clear copies at all times, clean the document cover and the document glass once
a month.
Note • Do not use benzene, paint thinner, or other organic solvents. Doing so might damage paint or coating
on plastic parts.
• Cleaning the machine with an excessive amount of water may cause the machine to malfunction or
damage documents during copying, faxing, or scanning.
