Use a blower to keep the interior of the scanner free of dust and paper particles.

Use a clean dry cloth to wipe dirt off the sensor glass.
Wipe both the top and bottom sensor glasses.
CAUTION
Do not use spray type cleaners to clean the scanner. Precision
mechanisms, such as the light source, may get wet which will
cause a malfunction.
IMPORTANT
Scratches on the sensor glass may cause marks on the images and could cause
feeding errors. If there are scratches on the sensor glass, contact your local
authorized Canon dealer or service representative.

Wipe the rollers with a firmly wrung cloth moistened with water.
IMPORTANT
• Do not use detergent to clean the rollers, since any detergent on the rollers
could cause a feeding error.
• If you cannot freely rotate the rollers, do not force them to rotate. Just clean
the part that you can see. Forcing the rollers to rotate may cause a feeding
error.
