Clean the lid backing
Minor debris can accumulate on the white document backing located underneath the lid
of the HP All-in-One.
To clean the lid backing
1. Turn off the HP All-in-One, unplug the power cord, and raise the lid.
2. Clean the white document backing with a soft cloth or sponge slightly moistened with
a mild soap and warm water.
Wash the backing gently to loosen debris. Do not scrub the backing.
3. Dry the backing with a dry, soft, lint-free cloth.
CAUTION: Do not use paper-based wipes, as these might scratch the backing.
4. If further cleaning is needed, repeat the previous steps using isopropyl (rubbing)
alcohol, and wipe the backing thoroughly with a damp cloth to remove any residual
alcohol.
CAUTION: Be careful not to spill alcohol on the glass or exterior of the HP All-
in-One, as this might damage the device.
5. Plug in the power cord, and then turn on the HP All-in-One.
