What Exactly is a Printer Drum Cartridge?

A drum unit is a maintenance item for your Brother printer (or other manufacturer Laser printer) that will occasionally required to be replaced but not as frequent as a toner cartridge.

A drum unit is a green metal cylinder or tube that carries a static electrical charge that attracts the toner powder from the printer toner cartridge and applies or “draws” it to the paper as it passes through the laser printer. Therefore, you will always find that drum unit is attached to the printer toner cartridge. They work hand in hand to produce excellent quality print out.
