Compatible Black Toner for Brother Printers

This new aftermarket cartridge replaces Brother TN850 and TN820 toner. It fits a wide range of Brother HL-L, DCP-L and MFC-L laser printers including the HL-L5000D, DCP-L5500DN and MFC-L6750DW. Offices and home users get a single black cartridge ready for immediate installation.

Consistent Output Across High Volumes

The cartridge is rated for 8000 pages at 5% coverage, matching the original specification. Laser print technology maintains sharp text and solid fills from the first page to the last without the density drop-off sometimes seen in short-run testing. A three-year warranty backs the sustained performance.

8000-Page Yield at 5% Coverage

This single figure decides whether the cartridge matches your print volume. Buyers who need a higher page count per cartridge or who use colour laser printers should look elsewhere.
