Twelve-Pack Black Toner Cartridge

The Laser Tek Services TN850 compatible cartridge replaces OEM TN850 and is sold as a twelve-pack of black toner. Each cartridge yields up to 8,000 pages for high-volume printing. Manufactured under ISO 9001 and ISO 14001 factory standards, they are built for consistent output from the first page to the last.

Offices Using Listed Brother Laser Printers

This pack suits offices that run any of the compatible Brother DCP, HL or MFC models shown in the specifications and want a bulk supply of black toner. Buyers who need colour toner or whose printers are not on the supported model list should look elsewhere.

8,000-Page Yield Per Cartridge

The rated yield of 8,000 pages per cartridge is the key figure for calculating total cost of ownership and planning replacement intervals across a fleet of printers. If your print volume demands a different yield rating, this pack will not match that requirement.

Questions about this item

How many pages can I expect from one TN850 cartridge in my Brother printer?

Each cartridge is rated for 8,000 pages at standard coverage, so a single unit should last through that volume before replacement is needed.

What connection standard does this toner use and does it limit print speed?

The cartridge installs directly into the printer's toner bay with no data interface; it does not restrict the engine speed of any compatible Brother model.

Will the 12-pack cartridges fit my Brother DCP-L5500DN without modification?

Yes, the TN850 is designed to the same physical dimensions as the OEM cartridge and seats normally in all listed Brother DCP, HL and MFC models.
