High-Yield Black Toner for Brother Printers

This Ninestar Technology TN770 cartridge replaces the Brother TN770 and TN-770 models with a high-yield black toner formulation. It is built for owners of HL-L2370DW, HL-L2379DW, MFC-L2750DW and MFC-L2759DW printers who need consistent monochrome output. The single-pack unit is new and carries a two-year shelf life when stored correctly.

Print Quality Over Extended Runs

The cartridge is rated to operate between 10°C and 30°C with 20% to 80% humidity, so it maintains density during long print sessions in typical office environments. Storage limits of -20°C to 40°C and the same humidity range help preserve toner integrity between jobs. The manufacturer states the product meets or exceeds OEM requirements for reliable performance.

Verify Printer Model Before Ordering

Confirm your device appears in the compatible list: HL-L2370DW, HL-L2379DW, MFC-L2750DW or MFC-L2759DW. This cartridge only supplies black toner, so colour printing is not supported. Users who require colour output or a different page-yield tier should look for an alternative product.
