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.
