Replace the drum unit.
To replace the drum unit follow the instructions listed below:
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.
Just after you have used the machine, some internal parts of the machine are extremely HOT! When you open the front cover of the machine, never touch the shaded parts as shown in the diagram below:
Open the front cover.
Remove the old drum unit. Place the drum unit on a drop cloth or large piece of disposable paper to avoid spilling and scattering the toner.
If you are not sure of them, call your local Sanitation Department.
