FAQs & Troubleshooting

Replace the drum unit.

Follow the procedure below to replace drum unit.


The Brother machine has separate consumables - the toner cartridge and the drum unit. Verify you replace only the drum unit and not the toner cartridge. If you want to know their difference, refer to "What is the difference between the toner cartridge and the drum unit?"


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.



For the order number (Order No.) of the drum unit, please refer to the User's guide provided with your Brother Printer or the Consumables & Options page of your model on Brother Solutions Center. To visit Consumables & Options page, click your model name link (e.g. HL-XXXX * ) on the top section and then click "Consumables & Options" link on the opened page. * XXXX stands for your model name.

  1. Open the top cover of the printer.
  2. Pull out the drum unit assembly (drum unit with the toner cartridge).
  3. Push down the blue lock lever and take the toner cartridge out of the drum unit assembly.
  4. Unpack the new drum unit.
  5. Put the toner cartridge into the new drum unit. If you insert the cartridge properly, the blue lock lever is lifted automatically.


    Make sure you install the toner cartridge properly, or it may separate from the drum when you pick up the drum unit.

  6. Put the drum unit assembly in the printer.
  7. Reset the drum counter following the instructions we have supplied with the new drum unit.

  8. Close the top cover of the printer.
