Description
Compatible Models: Brother DCP-B7500D, DCP-B7530DN, DCP-B7535DW, DCP-B7520DW, HL-B2000D, HL-B2050DN, HL-B2080DW, MFC-B7700D, MFC-B7715DW, MFC-B7720DN. Note: the source listing also names "DCP-L2531DW" alongside this B-series family - that specific pairing is a commonly-repeated cross-listing seen across several independent sellers' catalogs, but we could not independently confirm it as a genuine shared-part fitment, so it's flagged here rather than asserted as confirmed.
What It Is: The Drum Unit (also called the Imaging Drum or OPC Unit) - the photosensitive cylindrical drum inside a laser printer that the laser writes the page image onto before toner is transferred to it, then to the page. A worn, scratched or expired drum causes faint or streaky prints, repeating marks/spots down the page at a fixed interval, ghosting of the previous printed image, or a 'drum low/replace drum' error.
Part Number: DR-B021 Drum Unit - confirmed genuine, and sold separately from this same family's TN-B021 toner cartridge (a related but physically distinct part already listed in this catalog under a different batch, sharing the identical compatible-model description text this listing uses - not a duplicate, just the drum-and-toner pairing for the same printer family).
Condition: New / New Import - aftermarket replacement part.
Important: This item is sold as-is. No replacement, no warranty and no guarantee is offered on this part, and it is non-returnable once shipped - please confirm your exact model and part number with us before ordering.
