Brother DR-851CL Genuine Drum Unit 30,000 Pages

One. The DR-851CL is a single drum unit that carries all four colours - the four toner cartridges clip into colour-coded sections of the same part. There are no separate per-colour drums in this range.

The toner cartridges hold the powder that forms the image; the drum is the photosensitive surface that carries it to the paper. A colour laser needs both, plus a belt unit and a waste toner box, and all four are on different replacement schedules.

Because job length changes drum life substantially. Brother rates it at approximately 30,000 pages at one page per job and approximately 100,000 pages at three pages per job. If you print mostly multi-page documents, expect the higher figure. If you print single pages all day, plan on the lower one.

The printer names the part. Faded print is usually toner; repeating marks or bands down the page are usually the drum; colour that is slightly out of register is often the belt unit. The machine tracks the drum, the BU-800CL belt and the WT-800CL waste box separately and will tell you which one it wants.

Brother Australia lists the HL-L9470CDN, MFC-L9630CDN and MFC-L9670CDN. Colour drum codes are easy to confuse between neighbouring generations, so if your model is not on that list, check with us before ordering.

The TN-851 and TN-851XL toner range, the BU-800CL belt unit and the WT-800CL waste toner box. A useful rule: the drum code tracks the toner code rather than the printer number, so if you know your toner you can identify your drum.
