Your Brother printer uses a toner cartridge and drum unit to print. A toner cartridge is the container that holds the toner powder. The drum unit is the electrically charged cylinder that transfers that toner powder to paper to create text and images. Toner cartridges and the drum unit are sold separately for this machine. The toner cartridge usually needs to be replaced first, while the drum unit generally should be replaced after the use of 3 or 4 toner cartridges. The toner clicks into the drum and the two consumables install into the printer together as one piece. Learn more about the difference between a toner cartridge and a drum unit in this helpful blog article!
