How do I replace the Fuser Unit & Transfer Roll Cartridge?


  • Never touch the labeled area found on or near the heat roller. You can get burnt. To avoid injuries or burns, if a sheet of paper is wrapped around the heat roller, do not try to remove it by yourself. Switch off the printer immediately, and contact Brother Customer Service.
  • Be sure to switch off and unplug the printer before accessing the interior of the printer for cleaning, maintenance, or fault clearance. Access to a live printer's interior can cause electric shock.
  • Never throw a transfer roll cartridge into a naked/open flame. It can cause an explosion and you can get burnt.
  • Do not replace the fuser unit immediately after using the printer. You may get burnt.
  • Do not remove and reinsert the transfer roll cartridge in use.
  • When the message to replace the transfer roll cartridge appears, replace the transfer roll cartridge immediately. Otherwise, the printer will stop printing.

Follow the procedure below to replace the Fuser Unit & Transfer Roll Cartridge.

  1. Turn off the printer power switch and leave it for 30 minutes until the fuser unit cools down.

  2. Remove any paper from the center output tray.

  3. Open the back cover by lifting the lower gray lever at the top left corner of the back of the printer.

    Do not touch any parts inside the printer.
