Brother DR-3400 Drum Unit Guide

Brother DR-3400 Drum Unit

Check the full printer model and drum code before ordering.

What the DR-3400 code refers to

DR-3400 is a Brother image drum unit, not a toner cartridge. Check the message on the printer and the complete printer model before replacing a part; a drum and a toner cartridge are different consumables.

Brother’s UK support lists DR-3400 for the MFC-L5750DW and gives estimated drum life of about 30,000 pages at one page per job or 50,000 pages at three pages per job. These are test estimates for that model and usage pattern, not a guaranteed life for every printer or replacement unit. See Brother’s MFC-L5750DW consumables information; for other models, select the exact model on Brother Support.

Before buying, compare the part number on your existing drum unit with the printer’s model-specific consumables listing. If you need help, call Cartridge Care on 0161 738 1066, Monday to Friday, 9am–6pm.

Check the printer model before choosing a drum unit

The model names shown in the original 2017 version of this page have not been checked as a current compatibility list, so they have been removed rather than presented as a guarantee. Brother’s consumables pages are model-specific: select your exact printer model and confirm the drum unit code shown there.

As one verified example, Brother lists DR-3400 for the MFC-L5750DW. That example is not a compatibility statement for the other printers once listed on this page.

Search the online catalogue for DR-3400 products, then compare the listing with your printer’s exact model. If you are unsure, ring Cartridge Care on 0161 738 1066 before ordering.
