Brother DR-3425 Genuine Drum Unit 30,000 Pages

They are two separate parts. The toner cartridge holds the powder that forms the image; the drum unit is the photosensitive cylinder that carries it to the paper. A laser printer needs both, and they wear out at different rates - the drum typically lasts several toner cartridges.

Faded, patchy or light print generally means the toner is low. Marks, bands, lines or ghosting that repeat at the same interval on every page generally mean the drum. Your printer also tracks drum life separately and will display a drum warning when it is due.

Because job length changes drum life. The drum cycles every time the printer starts a job, so short jobs wear it faster per sheet. Brother rates it at approximately 30,000 pages at one page per job and approximately 50,000 pages at three pages per job.

Brother Australia lists the HL-L5100DN, HL-L5200DW, HL-L6200DW, HL-L6400DW, MFC-L5755DW, MFC-L6700DW and MFC-L6900DW. If your model is not on that list, ask us before ordering - drum codes are easy to confuse between neighbouring printer generations.

The TN-3420, TN-3440, TN-3470 and TN-3490 range. A useful rule: the drum code tracks the toner code rather than the printer number, so if you know which toner your machine takes you can identify the drum.

Not usually. The drum outlasts several toner cartridges, so they come due on different cycles. Replace whichever the printer asks for - there is no need to change both together.
