How do I clean the corona wire?

If you have print quality problems, clean the corona wire as follows:
NOTE: Illustrations shown below are from the representative product and may differ from your Brother machine.


Do NOT use flammable substances near the machine. DO NOT use flammable substances, any type of spray, or an organic solvent/liquid that contains alcohol or ammonia to clean the inside or outside of the machine.

  1. Turn off the machine's power switch.
    Unplug the telephone line cord first (for MFC users) and disconnect all cables, and then unplug the power cord from the AC power outlet.

  2. Open the front cover and slowly take out the drum unit and toner cartridge assembly.

  • We recommend that you place the drum unit and toner cartridge assembly on a clean, flat surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.

  • Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.

  • To prevent damage to the machine caused by static electricity, DO NOT touch the electrodes shown in the illustration.

  1. Clean the corona wire inside the drum unit by gently sliding the blue tab from right to left and left to right several times.

Be sure to return the blue tab to the home position (1). If you do not, printed pages may have a vertical stripe.

  1. Put the drum unit and toner cartridge assembly back in the machine.
  1. Close the front cover.

  2. Plug the machine's power cord back into the AC power outlet first, and reconnect all cables and telephone line cord (for MFC users). Turn on the machine's power switch.

To avoid print quality problems, DO NOT touch the shaded parts shown in the illustrations below.
