Why choose the genuine Brother BU-223CL belt unit
The BU-223CL is the genuine belt unit of Brother HL-L3200, DCP-L3500 and MFC-L3700 color laser printers and all-in-ones. It receives the four colors laid down by the DR-243CL drum and transfers them onto the sheet in a single pass. Rated for about 50,000 pages, it is replaced far less often than the toners; a genuine belt avoids color misregistration, marks and jams.
Belt, drum and toner: three different consumables
The toner holds the powder, the DR-243CL drum (18,000 pages) lays it on the belt, and the BU-223CL belt transfers it onto the sheet. The belt lasts about 50,000 pages, i.e. several drums and many toners. The printer shows "Replace belt unit" at end of life; regular marks or color misregistration are the other sign.
Printers compatible with the BU-223CL
The BU-223CL is compatible with 9 Brother models (manufacturer list):
Check the exact reference on the label at the back or underneath the printer; the suffixes (D, DW, DN, CDW) matter.
Page yield
About 50,000 pages according to the manufacturer. Actual life depends on the type of jobs: one-page jobs wear the belt faster than long runs. Per page, the belt cost is low; it is shown next to the price for comparison.
Installation and maintenance
Tool-free replacement: open the front cover, remove the drum + toner assemblies, lift out the used belt by its handles, insert the new BU-223CL, put the assemblies back and close the cover; the printer resets the counter. Do not touch the belt surface. Used Brother parts can be returned free of charge through the Brother recycling program.
Use and tips
The BU-223CL belt (50,000 pages) is designed to last the life of most moderately used printers (over 4 years at 1,000 pages per month); replace it when "Replace belt unit" is displayed.
Keep the part in its packaging until installation and do not touch the belt surface. Color misregistration or regular marks across the full width indicate a worn belt; the printer resets the counter after replacement.

Frequently asked questions
Is the BU-223CL compatible with my Brother printer?
Yes if it appears in the list above (HL-L3210CW to MFC-L3770CDW). If in doubt, compare the exact reference of your printer, suffix included.
When should the belt unit be replaced?
When the printer shows "Replace belt unit", about every 50,000 pages. Color misregistration or regular marks across the full width of the page are the other sign.
Does the belt come with the drum or the toner?
No. The BU-223CL is a separate part; the DR-243CL drum and the toners are replaced independently, each at its own pace.
Can the belt be cleaned instead of replaced?
No. The surface must not be touched or cleaned; a belt at end of life is replaced.
Where can I find the safety data sheet (SDS) for the BU-223CL?
