If the automatic document feeder picks up multiple pages or if it does not pick up plain
paper, you can clean the rollers and separator pad. Lift the automatic document feeder
cover to access the pick assembly inside the automatic document feeder, clean the rollers
or separator pad, and then close the cover.
If you have lines or dust appearing on scanned documents or faxes, clean the plastic strip
in the ADF.

To clean the rollers or separator pad

Remove all originals from the document feeder tray.
2. Lift the automatic document feeder cover (1).

This provides easy access to the rollers (2) and separator pad (3), as shown below.

4. Lift the automatic document feeder mechanism.

5. Clean the plastic strip with a soft cloth or sponge slightly moistened with a nonabrasive

glass cleaner.

CAUTION: Do not use abrasives, acetone, benzene, or carbon tetrachloride on
the plastic strip, since they can damage it. Do not place or spray liquid directly on
the plastic strip. The liquid might seep under the glass and damage the device.

plastic strip, and then close the cover of the automatic document feeder.

NOTE: If you still see dust or lines on scans after cleaning the plastic strip, you
may need to order a new plastic strip. For more information, see
