Cleaning the printer
General cleaning
To maintain print quality, clean the printer thoroughly:
● every time you change the print cartridge.
● whenever print-quality problems occur.
Clean the outside of the printer with a lightly water-dampened cloth. Clean the inside with only a
dry, lint-free cloth. Observe all warnings and cautions that appear with the cleaning tasks on the
following pages.
WARNING! Avoid touching the fusing area when cleaning the printer. It can be hot.
CAUTION To avoid permanent damage to the print cartridge, do not use ammonia-based cleaners on or
around your printer.
To clean the printer
1 Before you begin these steps, turn the printer off and disconnect all cables, including the
power cable.
2 Open the front cover of the printer and remove the print cartridge.
CAUTION To prevent damage to the print cartridge, use two hands when removing it from the printer.
Do not expose the print cartridge to light for more than a few minutes. Cover the print cartridge
when it is outside of the printer.
Note If toner gets on your clothes, wipe it off with a dry cloth, and wash your clothes in cold water. Hot
water sets toner into fabric.
