Clean the drum unit

If you have print quality problems, the drum may have foreign material, such as glue from a label stuck on the drum surface.

Please follow the steps below to solve the problem:

NOTE: Illustrations shown below are from representative product and may differ from your Brother machine.


  • DO NOT use cleaning materials that contain ammonia, alcohol, any type of spray, or any type of flammable substance to clean the outside or inside of the machine. Doing this may cause a fire or electrical shock.
    DO NOT use
  • Be careful not to inhale toner.
  1. Prepare blank A4 or Letter size paper.
  2. Make sure the machine is in Ready mode.
  3. Open the back cover (face-up output tray).

    Open the back cover.

  4. Open the manual feed slot cover.

    Open the manual feed slot cover.

  5. Press Clear and Menu at the same time. The Drum Cleaning message will appear on the LCD.

  6. Using both hands, slide the manual feed paper guides to the width of the paper that you are going to use.

    Set the manual feed paper guides.

  7. Using both hands, put one piece of A4 or Letter size paper until the top edge of the paper touches the paper feed roller. When you feel the machine pull in the paper, let go. The machine will start the Drum Cleaning process.

    Put paper in the manual feed slot.

    • The machine makes a mechanical noise during the Drum Cleaning process because the machine rotates the OPC drum in reverse. This noise is not due to a malfunction of the machine.

    • DO NOT put more than one sheet of paper in the manual feed slot at any one time, as it may cause a jam.

    • If the paper in the manual feed slot is other than A4 or Letter size, the machine will stop the Drum Cleaning process and eject the paper.

    • Make sure that the paper is straight and in the proper position in the manual feed slot. If it is not, it may not be fed properly, resulting in a skewed printout or a paper jam.

    • DO NOT close the back cover (face-up output tray) during the Drum Cleaning process. The machine will stop the Drum Cleaning process and eject the paper. It may cause a jam.

    • If the machine receives a print job before you put the sheet of paper in the manual feed slot, the machine will finish the Drum Cleaning process first, and then print the print job.

  8. When the machine has finished cleaning, the machine returns to Ready mode.

  9. Repeat steps 5 to 8 two more times using a new blank sheet of paper each time. Upon completion please discard the used paper.

If the problem is not solved yet, follow the steps below:
