Four-pack black toner replacement for Brother

This set contains four new black toner cartridges engineered to replace Brother TN850 and TN820 originals. It is designed for offices and workgroups that print high volumes on compatible Brother laser printers and want a lower cost per page without changing hardware.

Yield rated at 8000 pages per cartridge at 5%

Each cartridge is rated for approximately 8000 pages when printed at the industry-standard 5% page coverage. Actual output will vary with document density, print mode and environmental conditions such as temperature between 10 and 32.5°C and humidity between 20% and 80% RH during operation.

Replaces OEM Brother TN850 and TN820 cartridges

The pack directly substitutes the original Brother TN850 high-yield and TN820 standard-yield black toners. The upgrade is worthwhile when your print volume justifies the high-yield rating and you want to reduce the frequency of cartridge changes across the supported Brother DCP, HL and MFC series.

Questions about this item

Should I buy the 4-pack or a single cartridge for my Brother HL-L6200DW?

The 4-pack supplies four black cartridges at 8000 pages each, lowering the cost per page for high-volume printing on the HL-L6200DW.

What does the 8000-page yield mean for daily office use on a Brother MFC-L6900DW?

At 5% coverage each cartridge prints roughly 8000 pages, so a typical office printing 200 pages a day would replace one cartridge about every 40 working days.

Does the cartridge chip work with the Brother DCP-L5650DN firmware?

Yes, the chip is engineered for Brother TN850 and TN820 models and is recognised by the DCP-L5650DN and the other listed printers.
