Clean the exterior
WARNING! Before cleaning the device, turn off the power and unplug the power
cord from the electrical socket.
Use a soft, damp, lint-free cloth to wipe dust, smudges, and stains off of the case. The
exterior of the device does not require cleaning. Keep fluids away from the interior of the
device, as well as from the device control panel.
Clean the automatic document feeder (ADF) (Some models only)
NOTE: The ADF is available for some models only.
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
1. 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.
1 Automatic document feeder cover

3. Lightly dampen a clean lint-free cloth with distilled water, then squeeze any excess
liquid from the cloth.
