Do I need a toner or a drum? Customers always ask us this question, and the answer is YES, you need them both to use your Brother printer. Toner cartridges hold the toner powder to create a print and the drum unit transfers and applies the toner powder to the page. For this printer, the toner cartridge clicks into the drum unit and the two components install into the machine together as one piece. Toner cartridges usually need to be replaced first, while the drum unit generally lasts for 3-4 toner cartridges.
