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.

alcohol to dampen the cloth or sponge, and then wipe the backing thoroughly with a damp cloth
to remove any residual alcohol.
