Keep your Brother laser printer in top working condition by installing this replacement transfer belt unit. The transfer belt is an integral part of your printer and assists in the transfer of toner to the page. Over time, the transfer belt unit in your printer will diminish in performance due to wear and tear, so Brother recommend replacing the unit at 50,000 page intervals. Your printer will display a Belt End Soon error when it's time to install a fresh belt. This belt is suitable for use in Brother DCP-L8400DN, HL-L8250CDN, HL-L9200CDWT, MFC-L8850CDW, DCP-L8450CDW, HL-8350CDW, MFC-L8650CDW and MFC-L9550CDWT machines.
