How can I clean the inside of the printer?

Clean the inside of the printer 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.

When you clean the inside of the printer, pay attention to the following:

 

  • 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.
  • The fusing unit and the parts around it are hot! Never touch the shaded areas shown below.
  • Never touch or clean the transfer roller because print quality may be adversely affected.
  • Be careful not to inhale the toner.

 

  1. Turn off the printer power switch and unplug the printer.
