Minor debris can accumulate on the white document lid backing that is located underneath the all-in-
one lid.


Turn off the all-in-one, unplug the power cord from the electrical socket, and raise the lid.


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.


Wash the backing gently to loosen debris; do not scrub the backing.


Dry the backing by using a chamois or soft cloth.


Do not use paper-based wipes because they might scratch the backing.


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.


Cleaning the all-in-one



In certain areas of California, air pollution control regulations restrict the use of

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.
