Cleaning the MFP
General cleaning
To maintain print quality, clean the MFP thoroughly:
● every time you change the print cartridge
● whenever print-quality problems occur
Clean the outside of the MFP with a lightly water-dampened cloth. Clean the inside with only a
dry, lint-free cloth. Observe all warnings and cautions regarding the cleaning tasks.
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.
To clean the paper path
1 Before you begin these steps, turn the MFP off (button out) and disconnect all cables,
including the power cord.
2 Open the front cover of the MFP, rotate the green lever downward to the unlocked position,
and remove the print cartridge.
CAUTION To prevent damage to the print cartridge, use two hands when removing it from the MFP.
Do not expose the print cartridge to light for more than a few minutes. Cover the print cartridge
when it is outside of the MFP.
