The genuine Brother DR-4000 drum unit is an integral part of your laser printer, and needs to be replaced around about every three to four TN-4100 toners you have depleted. Your printer will warn you when the drum will soon need to be renewed. The drum unit does not contain any toner - it's function is to transfer the image onto the page. With Brother laser products the toner and drum work independently – this is cheaper to run than those where the two units are combined. If one runs out, you don't have to replace both items simultaneously, substantially reducing waste, saving precious resources and your cash. Ensure crisp clear prints every time using Original Brother consumables.
