True Color Toner TCT-TN439K High Yield Black

This True Color Toner cartridge replaces the Brother TN439K and delivers approximately 9000 pages at five percent coverage. It is designed for users who need reliable black output on compatible Brother colour laser printers. The single-pack format suits home offices and small workgroups with steady print volumes.

Printer model compatibility check

Verify that your device appears in the supported list: HL-L8360CDW, HL-L8360CDWT, HL-L9310CDW, MFC-L8900CDW or MFC-L9570CDW. Confirm the printer currently uses a TN439K black cartridge and that the toner slot is accessible. No firmware version or regional variant is specified, so match the model number exactly before ordering.

Build integration notes

The cartridge installs directly into the black toner bay of the listed Brother machines with no additional hardware required. Its high-yield capacity reduces replacement frequency, freeing up storage space and minimising downtime during large print runs. Buyers who need colour toners or a multi-pack bundle should look for separate listings.

Questions about this item

Does the TCT-TN439K cartridge ship alone or in a multi-pack?

The box contains a single black cartridge. No drum unit, waste toner box or extra cartridges are included.

Should I choose the TCT-TN439K or the standard TN439 for my HL-L8360CDW?

The TCT-TN439K is the high-yield black model rated for 9000 pages at 5 % coverage. The standard TN439 yields fewer pages.

Will I really get 9000 pages from the TCT-TN439K in my MFC-L8900CDW?

The 9000-page figure follows the industry 5 % coverage test. Heavy graphics, dense text or frequent short jobs will reduce the actual count.
