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

Please follow the steps below to replace the toner cartridge:

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

  1. Make sure that the machine is turned on.

  2. Press the front cover release button and then open the front cover.


  3. Hold the green handle of the drum unit. Pull the drum unit out until it stops.


  4. Hold the handle of the toner cartridge and slightly push it toward the machine to unlock it. Then pull it out of the drum unit. Repeat this for all the toner cartridges.


    • DO NOT put a toner cartridge into a fire. It could explode, resulting in injuries.

    • DO NOT use cleaning materials that contain ammonia, alcohol, any type of spray or any type of flammable substance to clean the inside or outside of the machine. Doing this may cause a fire or electrical shock.

    • Be careful not to inhale toner.


    • We recommend that you place the drum unit and/or the toner cartridge on a clean, flat, level, stable 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 avoid print quality problems, DO NOT touch the shaded parts shown in the illustration.

    • Be sure to seal up the toner cartridge tightly in a suitable bag so that toner powder does not spill out of the cartridge.

    • Go to for instructions on how to return your used consumable items to the Brother collection program. If you choose not to return your used consumable, please discard the used consumable according to local regulations, keeping it separate from domestic waste. If you have questions, call your local waste disposal office.
