The Part That Keeps Your Colours Lined Up

The genuine Brother BU-320CL is a colour laser belt unit - the part that carries toner from the drum to the page and keeps the four colours in register - rated by Brother at approximately 20,000 pages at one page per job or approximately 50,000 pages at five pages per job.

A colour laser has four wear parts, not one: the toner cartridges, the drum, the belt unit and the waste toner box. The belt is the one most people have never heard of, and it is the one that governs colour alignment. Brother's own fault guidance for colour offset and for a failed colour registration ends with the same instruction - install a new belt unit. If your colours are very slightly out of line with each other, this is the part to look at before anything else. Brother Australia has removed this printer generation from its website, so there is no compatibility list on the product page any more. Brother's own support site still lists this belt unit against the HL-L8250CDN, HL-L8350CDW, MFC-L8850CDW and MFC-L9550CDW. If your machine is not named here, send us the model and we will confirm before you order.

Brother rates this belt unit two ways, and the gap between them is the point: approximately 20,000 pages at one page per job, and approximately 50,000 pages at five pages per job. Like a drum, it wears by how often the machine cycles rather than purely by sheets, so short jobs consume it faster per page. Work out which pattern your office actually prints before you plan around either number.

Your printer will warn you before it stops. Brother's display shows Belt End Soon first, which is the point at which to order, and Replace Belt when it is due. One step people miss: after fitting a new belt you must reset the belt counter in the machine's Parts Life menu, or the printer keeps counting the old one. It works with the DR-341CL drum, the TN-341 and TN-346 toner range and the WT-320CL waste toner box, and the printer reports each of them separately, so they rarely fall due together. Using the genuine Brother part keeps the printer's own parts-life counters accurate, which is what lets it warn you in advance instead of failing mid-job. Replacement is an end-user job.

FAQs

It carries toner from the drum across to the paper and keeps all four colours in register while it does. Brother's own guidance for colour offset and for a failed colour registration both end with the instruction to install a new belt unit, so it is the part to suspect when colours are slightly misaligned rather than faded.
Yes, and it is easy to miss. You must reset the belt unit counter in the machine's Parts Life menu, otherwise the printer carries on counting the old belt and will not warn you correctly next time. Brother also says not to reset that counter unless you have actually changed the belt.
Because job length changes how fast the part wears. It cycles each time the printer starts a job, so short jobs use it up faster per page. Brother rates it at approximately 20,000 pages at one page per job and approximately 50,000 pages at five pages per job.
The printer tells you, in two stages. It shows Belt End Soon first, which is when to order one, then Replace Belt when it is actually due. It tracks this part separately from the toner and the drum, so they rarely come due at the same time.
Brother Australia has removed this printer generation from its website, so we publish only the models still confirmed on Brother's support site: the HL-L8250CDN, HL-L8350CDW, MFC-L8850CDW and MFC-L9550CDW. Tell us your model and we will confirm the fit rather than guess.
A colour laser has four wear parts. Alongside this one you will eventually need the DR-341CL drum, the TN-341 and TN-346 toner range, the BU-320CL belt unit and the WT-320CL waste toner box. Each is tracked separately by the machine.
