Please follow the steps below to solve the problem:

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 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.
    Do Not Use
  • Be careful not to inhale toner.
  • DO NOT unpack a spare drum unit until immediately before you put it into the machine. If drum unit is exposed to sunlight or room light the unit may be damaged.
  • We recommend that you clean the machine when you replace the consumables. For the details of cleaning the printer, please refer to the "Cleaning" section in User's guide or FAQ in the "Maintenance" section of your model.


  1. Make sure that the machine is turned on. Leave the machine for at least 10 minutes to cool down.
