How can I clean the inside of the machine?

Clean the inside of the machine as follows.


Do NOT use flammable substances or any type of spray to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.

Cleaning to prevent paper jams:


  • The fusing unit and the parts around it are hot! Never touch the shaded areas shown below.
  • Be careful not to inhale the toner.
  • When you clean parts inside the machine, use a clean, dry soft, lint-free cloth. Do not use Isopropyl alcohol.
  • If your clothes are smeared with toner, wipe off the toner with a dry cloth. Immediately wash your clothes in cold water to avoid stains.
  • Never touch the transfer roller because print quality may be adversely affected.


  1. Before you clean the inside of the machine, turn off the machine's power switch. Unplug the telephone line cord first, and then unplug the power cord from the AC power outlet. Open the back cover of the machine.


  1. Clean the registration roller and the paper pick-up roller with a dry soft, lint-free cloth to prevent paper jams.


    • Be careful you do not break the actuator while cleaning the registration roller and paper pick-up roller.
    • Make sure you do not put too much pressure on the registration roller and paper pick-up roller. This could damage them and cause poor print quality.
