Clean the glass
Glass that is dirty from fingerprints, smudges, hair, and dust on the main glass surface
slows down performance and affects the accuracy of some features.
To clean the glass
1.
Turn off the HP All-in-One, unplug the power cord, and raise the lid.
2. Clean the glass with a soft cloth or sponge slightly moistened with a nonabrasive
glass cleaner.
Caution Do not use abrasives, acetone, benzene, or carbon
tetrachloride on the glass, since they can damage it. Do not place or spray
liquid directly on the glass. The liquid might seep under the glass and
damage the device.
3. Dry the glass with a dry, soft, lint-free cloth to prevent spotting.
4. Plug in the power cord, and then turn on the HP All-in-One.
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.
