Clean the scanner lid backing
Minor debris can accumulate on the white document lid backing that is located underneath the scanner
lid.
1. Open the scanner lid.
2. Clean the white document lid backing by using a soft cloth or sponge that has been moistened with
a mild soap and warm water. Also, clean the scanner strip next to the ADF scanner glass.
3. Wash the backing gently to loosen debris; do not scrub the backing.
4. Dry the backing by using a chamois or soft cloth.
CAUTION Do not use paper-based wipes because they might scratch the backing.
5. If this does not clean the backing well enough, repeat the previous steps and use isopropyl alcohol
to dampen the cloth or sponge, and then wipe the backing thoroughly with a damp cloth to remove
any residual alcohol.
Clean the ADF
If the ADF has trouble feeding documents, clean the ADF pickup roller assembly.
1. Turn off the device and unplug the power cord.

NOTE In certain areas of California, air pollution control regulations restrict the use of
liquid Isopropyl Alcohol (IPA) as a cleaning agent. In those areas of California, please
disregard the previous recommendations and use a dry, lint-free cloth. The cloth may be
moistened with water if desired.
