  • Perform this task after every few months.
  • Damage to the printer caused by improper handling is not covered by the printer warranty.
  1. Turn off the printer, and then unplug the power cord from the electrical outlet.

  2. Remove paper from the standard bin and multipurpose feeder.

  3. Remove any dust, lint, and pieces of paper around the printer using a soft brush or vacuum.

  4. Wipe the outside of the printer with a damp, soft, lint‑free cloth.


    • Do not use household cleaners or detergents, as they may damage the finish of the printer.
    • Make sure that all areas of the printer are dry after cleaning.
  5. Connect the power cord to the electrical outlet, and then turn on the printer.

    CAUTION—POTENTIAL INJURY:  To avoid the risk of fire or electrical shock, connect the power cord to an appropriately rated and properly grounded electrical outlet that is near the product and easily accessible.
