Cleaning the Scanning Area
Wipe the scanning area (shaded area) with a clean, soft, lint-free cloth moistened
with water, then wipe with a clean, soft, dry, lint-free cloth.
Cleaning the ADF Area
Black lines may appear in copies when the ADF is used to feed documents.
This is caused by paste, ink, correction fluid, or other foreign matters in the read
area of the platen glass (shaded area). Use a clean soft cloth to wipe the read area
clean. Take particular care to clean at the locations where the black lines are
appearing on copies.
If you have trouble getting the glass clean, wipe with a cloth moistened with water
or a mild neutral detergent, and then wipe the glass dry with another cloth.
