To clean the scanner glass

Clean the scanner glass only if dirt is visible, or if you are experiencing a decrease in
copy quality, such as streaking.

Clean the scanner glass by wiping it gently with a clean, slightly damp, lint-free cloth.
Use an ammonia-based surface cleaner only when a water-dampened cloth does not
clean the scanner glass.


Do not pour or spray liquids directly onto the scanner glass. Do not press hard on the glass
surface. (You could break the glass).
