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.
