10-Pack Black Toner for Brother Printers

This pack contains ten new eSquareOne compatible toner cartridges that replace Brother TN850 and TN820 models. Each cartridge delivers an approximate yield of 8000 pages at 5% coverage. The cartridges suit offices or households with Brother laser printers listed in the compatibility data. They arrive ready to install and operate within 10 to 32.5°C.

Suits high-volume mono printing; not for colour

Buyers who run the listed Brother DCP, HL or MFC mono laser printers and want a bulk supply of black toner will find this pack convenient. Users needing colour output, drum units, or cartridges for printers outside the listed Brother range should look elsewhere. The 10-pack format also assumes storage space for spare units.

8000-page yield at 5% coverage per cartridge

The headline specification is the 8000-page yield measured at standard 5% coverage, which determines how long each cartridge lasts in typical office use. Actual page count varies with document density, print settings and environmental conditions within the stated 20 to 80% RH operating humidity range.
