Compatible black toner two-pack for Brother printers

This pack contains two new black toner cartridges that replace Brother TN750 and TN720 units. They fit the HL-5450DN, HL-5470DW, HL-5470DWT, HL-6180DW, HL-6180DWT, MFC-8510DN, MFC-8710DW, MFC-8810DW, MFC-8910DW, MFC-8950DW, MFC-8950DWT, DCP-8110DN, DCP-8150DN and DCP-8155DN models. Each cartridge is rated for approximately 8000 pages at 5% coverage.

Yield and consistency across long print runs

The 8000-page rating applies to each cartridge under the standard 5% coverage test. In sustained office use the toner maintains consistent density from the first page to the last without the gradual fade sometimes seen on lower-grade refills. The formulation is designed to match OEM page-count reliability so high-volume jobs finish without an unexpected swap.

Operating limits and environmental specs

The cartridges are warranted for use between 10 and 32.5°C with relative humidity from 20% to 80%. They can be stored from -20 to 40°C at the same humidity range. Production follows ISO 9001 and ISO 14001 quality management systems, and the supplier backs the product with a two-year guarantee and free replacement warranty.

Questions about this item

How much heat does the S1-BR-TN750-02 generate during all-day printing?

The cartridges operate between 10 and 32.5°C with 20 to 80% RH, so they add no extra heat beyond the printer's normal output.

Which printer must I already own for these two black cartridges to work?

They fit Brother HL-5450DN, 5470DW, 5470DWT, 6180DW, 6180DWT, MFC-8510DN, 8710DW, 8810DW, 8910DW, 8950DW, 8950DWT, DCP-8110DN, 8150DN or 8155DN.

Will the TN750 replacements run reliably in my older HL-5450DN alongside its original drum unit?

Yes, they are engineered to match Brother TN750 and TN720 specs, so they work with the existing drum in any listed model including the HL-5450DN.
