Replace Drum

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. Doing this may cause a fire or electrical shock.

We recommend that you place the drum cartridge on a clean, flat surface with a piece of disposable paper underneath it in case you accidentally spill or scatter toner.
To prevent damage to the machine from static electricity, DO NOT touch the electrodes shown in the illustration.

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