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.
To avoid damage to painted parts of the HP All-in-One, do not use
alcohol or alcohol-based cleaning products on the control panel, document
feeder tray, lid, or other painted parts of the device.
