any residual alcohol.
Clean the scanner glass
Dirty glass, from fingerprints, smudges, hair, and so on, slows down performance and affects the
accuracy of special features such as fit-to-page and copy.
NOTE:
If streaks or other defects appear only on copies produced using the automatic document
feeder (ADF), clean the scanner strip (step 3). It is not necessary to clean the scanner glass.
1.
Turn off the product, unplug the power cord from the electrical socket, and raise the lid.
2.
Clean the glass by using a soft, lint-free cloth or sponge that has been moistened with nonabrasive
glass cleaner.
CAUTION:
Do not use abrasives, acetone, benzene, ammonia, ethyl alcohol, or carbon
tetrachloride on any part of the product; these can damage the product. Do not place liquids directly
on the glass. They might seep under it and damage the product.
