Compatible Black Ink Cartridge Three-Pack

This three-pack supplies extra high-yield black ink cartridges built as replacements for Brother LC79BK originals. Each cartridge is rated for approximately 2400 pages at five percent coverage under the ISO/IEC standard. The set targets home offices and small businesses that print large volumes of monochrome documents and want a lower cost per page.

Fits Four Brother MFC Multifunction Models

The cartridges install directly into the MFC 5910DW, MFC 6510DW, MFC 6710DW and MFC 6910DW without hardware modification. Using compatible replacements frees budget that would otherwise go to brand-name supplies while keeping the existing printer fleet in service. No additional accessories or firmware steps are required beyond the normal cartridge swap.

Consistent Output Across Long Print Runs

Dye-based ink formulation is quality tested to maintain bold, vivid text from the first page through the full rated yield. Sustained high-volume printing does not degrade density or sharpness as the cartridge empties. The extra high-yield capacity reduces the frequency of replacements during heavy workloads, keeping workflow interruptions to a minimum.
