Replace the Drum Unit
Before starting the replacement procedure, see Related Information: Replace Supplies.
- Make sure the machine is turned on.
- Press the front cover release button and open the front cover.
- Hold the drum unit's green labeled handle. Pull the drum unit out of the machine until it stops.
- CAUTION
- We recommend placing the toner cartridge and drum unit assembly on a clean, flat surface with disposable paper underneath it in case you accidentally spill or scatter toner.
- Holding the green labeled handles of the drum unit, lift the front of the drum unit and remove it from the machine.
- IMPORTANT
-
Hold the handles of the drum unit when you carry it. DO NOT hold the sides of the drum unit.
- Unpack the new drum unit.
- Remove the protective cover.
- Hold the handle of the toner cartridge and pull the toner cartridge up and out of the drum unit. Repeat this for all toner cartridges.
- Reinsert the toner cartridge into the new drum unit. Make sure that you match the toner cartridge colour to the same colour label on the drum unit. Repeat this for all toner cartridges.

Make sure you put the toner cartridge in correctly or it may separate from the drum unit. - Gently slide the drum unit into the machine until it stops.
- Using the green labeled handle, push the drum unit back into the machine until it locks in place.
- Close the machine's front cover.
- NOTE
-
- Drum wear and tear occurs due to use and rotation of the drum and interaction with paper, toner, and other materials in the paper path. In designing this product, Brother decided to use the number of rotations of the drum as a reasonable determinant of the drum life. When a drum reaches the factory-established rotation limit corresponding to the rated page yield, the product’s LCD will advise you to replace the drum. The product will continue to function; however, print quality may not be optimal.
- If an unpacked drum unit is placed in direct sunlight (or artificial light for long periods of time), the unit may be damaged.
There are many factors that determine the actual drum life, such as the temperature, humidity, type of paper, type of toner used and so on. Under ideal conditions, the average drum life is estimated at approximately 100,000 pages based on 3 pages per job [A4/letter simplex pages]. The number of pages may be affected due to a variety of factors including but not limited to media type and media size.
Because we have no control over the many factors that determine the actual drum life, we cannot guarantee a minimum number of pages that will be printed by your drum.
For best performance, use only Brother Original toner.
- The machine should be used only in a clean, dust-free environment with adequate ventilation.
Printing with a non-Brother drum unit may reduce not only the print quality but also the quality and life of the machine itself. Warranty coverage does not apply to problems caused by the use of a non-Brother drum unit.
