Cleaning the HP All-in-One

  • PrintPrint

Introduction

To ensure that your copies and scans remain clear, you might need to clean the glass or the lid backing.
With normal usage, your HP All-in-One should be cleaned every six months; with high usage, clean it every three months.

Cleaning the all-in-one

Cleaning the glass

Fingerprints, smudges, hair, and dust on the main glass surface slow down performance and affect the accuracy of features such as Fit to Page.
In addition to cleaning the main glass surface, you might also need to clean the small glass strip inside the automatic document feeder. Streaks can occur if the glass strip inside the automatic document feeder is dirty.
To clean the glass
  1. Turn off the HP All-in-One, and raise the lid.
  2. Clean the glass with a soft cloth or sponge slightly moistened with a non-abrasive 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. Turn on the HP All-in-One.

Cleaning 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.
    NOTE:Depending how long the HP All-in-One is unplugged, the date and time might be erased. You might need to reset the date and time when you plug the power cord back in.
  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.

Cleaning 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.

Cleaning the automatic document feeder

If the automatic document feeder picks up multiple pages or if it does not pick up plain paper, you can clean the rollers and separator pad.
Lift the automatic document feeder cover to access the assembly inside the automatic document feeder, clean the rollers or separator pad, and then close the cover.
To clean the rollers or separator pad
  1. Remove all originals from the document feeder tray.
  2. Lift the automatic document feeder cover (1). This provides easy access to the rollers (2) and separator pad (3), as shown below.
    1 - Automatic document feeder cover
    2 - Rollers
    3 - Separator pad
  3. Lightly dampen a clean, lint-free cloth with distilled water, then squeeze any excess liquid from the cloth.
  4. Use the damp cloth to wipe any residue off the rollers or separator pad.
  5. Close the cover of the automatic document feeder.
To clean the glass strip inside the automatic document feeder
  1. Turn off the HP All-in-One, and unplug the power cord.
    NOTE:Depending how long the HP All-in-One is unplugged, the date and time might be erased. You might need to reset the date and time when you plug the power cord back in.
  2. Lift the cover of the automatic document feeder.
  3. Raise the lid as if you were loading an original on the glass.
  4. Lift the automatic document feeder mechanism.
    There is a glass strip under the automatic document feeder.
  5. Clean the glass strip with a soft cloth or sponge slightly moistened with a non-abrasive 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.
  6. Lower the automatic document feeder mechanism, and then close the cover of the automatic document feeder.
