How to Change a Drum in a Brother Printer

1. Put on latex gloves to protect your hands. Turn on the printer. Open the front cover.
2. Place a cloth or rag next to your printer. Pull the drum/toner cartridge slowly from the unit. Place the cartridge on the rag.
3. Push down on the green lever on the cartridge to free the toner portion from the drum. Throw away the old drum.
4. Unpack the new drum assembly. Place the toner cartridge into the new drum unit until you hear the cartridge click in place. The green lever will lock in an upright position. The toner cartridge will only fit in the drum unit in one direction.
5. Place the cartridge slowly into the printer. Press and hold the white button on the left side of the printer's frame by the drum assembly for four seconds. The lights on the printer will illuminate one by one.
6. Release the button once all four lights illuminate. The drum counter is now reset. Close the front cover.
