Compatible black toner for Brother printers

This three-pack of Cool Toner TN850 cartridges replaces Brother TN850 and TN820 supplies. It suits offices and home users who print high volumes on the listed Brother laser models. Each cartridge is new and designed for laser print technology.

Straightforward drop-in replacement

Installation follows the standard Brother cartridge swap: open the front cover, remove the old unit, shake the new cartridge gently, then slide it in until it clicks. The chip is pre-installed so the printer recognises it immediately. A common issue is forgetting to remove the protective seal before insertion, which causes blank pages.

8000-page yield at 5% coverage

The decisive specification is the approximate yield of 8000 pages per cartridge at 5% coverage. Buyers who need a higher per-cartridge page count or who use printers outside the compatible Brother DCP, HL and MFC series listed should look elsewhere.

Questions about this item

How can I verify the TN850 cartridge is printing correctly after installation?

Print a test page on your Brother HL-L5200DW or MFC-L5850DW; the output should be sharp black text at the rated 5% coverage, matching the 8000-page yield specification.

What comes in the 3-pack box and do I need any extra parts to use them?

The box contains three new black TN850 compatible toner cartridges; no additional components are required for installation in listed Brother printers such as the DCP-L5500DN or HL-L6200DW.

Should I choose the TN850 3-pack or the TN820 version for my Brother HL-L6200DWT?

Select the TN850 3-pack; it is rated for 8000 pages at 5% coverage and is listed as compatible with the HL-L6200DWT, whereas the TN820 is a lower-yield alternative.
