Cleaning the Scanning Glass and the Rollers
If scanned images contain streaks, or if the scanned documents
become dirty, the scanning glass or rollers inside the scanner may
be dirty. Clean them periodically.
1 Open the document feed tray. Press the OPEN button and pull open
the front unit toward you.
2 Use compressed air to remove dust and paper particles from the
inside of the scanner.
3 Clean the scanning glass.
Wipe the scanning glass with a cloth that has been dampened with water and
thoroughly wrung out, and then use a dry, soft cloth to wipe away any moisture.
Do not spray water or neutral detergent directly on the scanner.
Precision mechanisms, such as the light source, may get wet, and
cause a malfunction.
Scratches on the scanning glass may cause marks on the images, as
well as feeding errors. If there are scratches on the scanning glass,
contact your local authorized Canon dealer or service representative.
