❏Cleaning the Scanning Glass and Rollers
If scanned images contain streaks or scanned documents become dirty, the scanning glass and rollers inside the scanner may be dirty. Use the procedure below to clean them on a regular basis.
1.Pull the lock lever toward you and then fully open the panel unit.

CAUTION
The open/close movement of the panel unit is linked to the up/ down movement of the document eject tray. Do not press on the document eject tray when you open the panel unit.
2.Use a commercially available air blower to remove any dust and paper particles that have accumulated inside the scanner.
3.Use a clean, dry cloth to wipe any dirt off the scanning glass.
Scanning Glass
Hint
There is one scanning glass for the front side of documents, and another for the back side. Wipe both of them clean.
CAUTION
Do not spray water or detergent directly on the scanner. Doing so may damage precision mechanisms, such as the light source.
IMPORTANT
Scratches on the scanning glass may cause streaks on scanned images, as well as feeding errors. If there are scratches on a scanning glass, contact your local authorized Canon dealer.
