GREENCYCLE TN850 Black Toner Cartridge 6 Pack 8000 Pages

Six-pack black toner for Brother laser printers

This pack contains six new GREENCYCLE TN850 black toner cartridges built as aftermarket replacements for the Brother TN850 and TN820 originals. Each cartridge is rated for approximately 8000 pages at five percent coverage on letter or A4 paper. The set suits offices, schools, banks, hospitals and home users who run high-volume monochrome laser printing on the compatible Brother HL, DCP and MFC models listed by the supplier.

Yield measured at five percent coverage only

The 8000-page figure applies strictly to the industry-standard five percent page coverage test on letter or A4 media. Real-world yield drops when printing dense text, graphics, forms or smaller paper sizes because toner consumption rises with coverage. The cartridges are not MICR toner, so they cannot be used for cheque printing that requires magnetic ink character recognition.

Simple drop-in installation with sealed packaging

Each cartridge ships in a multi-layer sealed bag inside an anti-shock bubble wrap and outer box, protecting the drum and toner from contamination during transit. Installation follows the standard Brother cartridge swap: open the front cover, remove the old unit, shake the new cartridge gently side-to-side, pull the seal tab and insert until it clicks. The most common issue is forgetting to remove the full length of the sealing tape, which causes blank or streaked pages until cleared.
