Cleaning the device
The section contains information about cleaning the device.
To clean the exterior
Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off of the exterior of the
device.
To 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 device, unplug the power cord from the electrical socket, and raise the lid.
2. Clean the glass by using a soft 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 device; these can damage the device. Do not place liquids directly on the
glass. They might seep under it and damage the device.
3. Clean the scanner strip by using a soft cloth or sponge that has been moistened with
