Four-pack black cartridges for Brother MFC printers

This set contains four LC79BK extra high yield black ink cartridges from LD Products. Each cartridge delivers approximately 2400 pages at five percent coverage under the ISO IEC standard. The pack is designed for owners of Brother MFC 5910DW, 6510DW, 6710DW and 6910DW multifunction printers who print large volumes of monochrome documents.

Dye-based ink with consistent output

The dye-based formulation produces bold, vivid text on every page and is quality tested for long-lasting use. Because the cartridges are consumables, thermal load, noise and power draw are determined entirely by the printer itself. No additional cooling or power considerations apply beyond the printer's normal operation.

Direct replacement for LC79BK slots

Each cartridge fits the standard LC79BK slot in the listed Brother MFC models without adapters or firmware workarounds. The four-pack lets you stock spares so a depleted cartridge can be swapped immediately, keeping the printer ready for the next job. Buyers who need colour cartridges or a different yield tier will need separate items.

Questions about this item

How do I install the LC79BK cartridge in my Brother MFC-J6510DW, and what step is commonly missed?

Open the ink cover, remove the orange protective cap, insert the cartridge until it clicks, then close the cover and run the printer's alignment routine — skipping alignment causes streaky first pages.

What maintenance or replacement will the LC79BK four-pack need over time?

Each cartridge yields about 2400 pages at 5 % coverage; replace a cartridge when the printer reports low ink or print quality fades, and run a cleaning cycle if the printer sits idle for weeks.

What limit appears first during long, continuous printing with the LC79BK?

The 2400-page yield per cartridge is the first hard limit — after that volume the ink is exhausted and the cartridge must be swapped, regardless of print speed or duty cycle.
