64 Regular Maintenance
IMPORTANT
• 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.
• Be careful not to bend the guide boards that are against the rollers on the
Upper unit.
4.
Remove the pickup roller, feed roller, and retard roller. (See “Removing and
Attaching the Rollers,” on p. 67.)
5.
Wipe the removed rollers with a firmly wrung cloth moistened with water.
CAUTION
Do not use detergent to clean the rollers, since any detergent on
the rollers could cause a feeding error.
6.
Attach the rollers that were removed. (See “Removing and Attaching the
Rollers,” on p. 67.)
7.
Close the Upper unit slowly. Be sure that the Upper unit is completely closed
by pushing on both edges with both hands until you hear a click.
IMPORTANT
Do not force the Upper unit to close. Doing so may damage the scanner.
