Cleaning the Reversing Automatic Document Feeder (optional)
If the scanning area is dirty, it may cause an original jam or result in dirty copies.
Also, if the original transport belt is dirty, the copies may become solid or the original size may be
incorrectly detected.
- Clean the scanning area and the original transport
belt with a cloth moistened with a small amount of
water, alcohol or a neutral detergent, then wipe off
the detergent completely with a dry cloth.
