Cleaning the MFP
To maintain print quality, clean the MFP thoroughly whenever print-quality problems occur
and every time you replace the print cartridge.
WARNING! Avoid touching the fusing area when cleaning the MFP. It can be hot.
CAUTION To avoid permanent damage to the print cartridge, do not use ammonia-based cleaners on
or around the MFP except as directed.
Cleaning the outside of the MFP
● Clean the outside of the MFP if it is visibly marked.
● Use a soft, lint-free cloth dampened with water, or water and a mild detergent.
Cleaning the touchscreen
Clean the touchscreen whenever it is necessary to remove fingerprints or dust. Wipe the
touchscreen gently with a clean, water-dampened, lint-free cloth.
CAUTION Use water only. Solvents or cleaners can damage the touchscreen. Do not pour or spray
water directly onto the touchscreen.
To clean the scanner glass
● Clean the scanner glass only if dirt is visible, or if you are experiencing a decrease in
copy quality, such as streaking.
● Clean the scanner glass by wiping it gently with a clean, slightly damp, lint-free cloth.
Use an ammonia-based surface cleaner only when a water-dampened cloth does not
clean the scanner glass.
CAUTION Do not pour or spray liquids directly onto the scanner glass. Do not press hard on the glass
surface. (You could break the glass).
Cleaning the fuser
Use the MFP cleaning page to keep the fuser free of toner and paper particles that can
sometimes accumulate. Accumulation of toner and particles can cause specks to appear on
the front or back side of your print jobs.
CAUTION Do not attempt to clean the fuser with water or any other liquid. Use only the internal
cleaning page to clean the fuser.
To ensure optimum print quality, HP recommends that you use the cleaning page every time
you replace the print cartridge or on an automatic interval that you can set up.
The cleaning procedure takes about 2.5 minutes to complete. A CLEANING message
appears on the control-panel display while the cleaning is taking place.
