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, 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.

Clean the exterior

Use a soft cloth or slightly moistened sponge to wipe dust, smudges, and stains off the case. The interior of the HP All-in-One does not require cleaning. Keep fluids away from the control panel and the interior of the HP All-in-One.

CAUTION: To avoid damage to the exterior of the HP All-in-One, do not use alcohol or alcohol-based cleaning products.

Check the estimated ink levels

You can easily check the ink supply level to determine how soon you might need to replace an ink cartridge. The ink supply level shows an estimate of the amount of ink remaining in the ink cartridges.

NOTE: The HP All-in-One can only detect the ink levels for genuine HP ink. The ink levels in ink cartridges that are refilled or have been used in other devices might not register accurately.

NOTE: Ink from the cartridges is used in the printing process in a number of different ways, including in the initialization process, which prepares the device and cartridges for printing, and in printhead servicing, which keeps print nozzles clear and ink flowing smoothly. In addition, some residual ink is left in the cartridge after it is used. For more information, see www.hp.com/go/inkusage.
