Two-Pack Black Toner for Brother Printers

The TCT TN439K twin pack supplies two black cartridges rated at 9000 pages each at five percent coverage. It fits the HL-L8360CDW, HL-L8360CDWT, HL-L9310CDW, MFC-L8900CDW and MFC-L9570CDW models. Offices with steady mono output can load both cartridges and delay the next order.

Replaces Brother TN439K Ultra High Yield

Swapping an original Brother TN439K for this set cuts the cost per page while keeping the same 9000-page yield spec. The jump makes sense when monthly mono volume is high enough to use both cartridges before their shelf life ends. Buyers who print mostly colour or only a few hundred pages a month will not recover the upfront spend.

Drop-In Install With Chip Recognition

Each cartridge ships with its own chip so the printer recognises it immediately after the cover is closed. The only common snag is forgetting to pull the orange sealing strip before insertion, which leaves the first pages blank. A cold printer can also report a false low-toner warning until the first few pages run through.
