Four-Colour High-Yield Toner Set

This pack contains four new high-yield toner cartridges in black, cyan, magenta and yellow. Each unit includes a chip for direct recognition by the printer. The set is built for HP Color LaserJet Enterprise M578c, M578z, M554dn, M555dn, M555x, M578dn and M578f models. It replaces HP W2120X through W2123X (212X) originals.

Suits Offices Printing Colour Documents Daily

The four-cartridge bundle matches printers that use the full colour set at once. It fits environments where replacing all colours together simplifies stock control. Buyers who only need a single colour replacement should choose individual cartridges instead. Print volumes below the high-yield threshold may not use the full capacity before the two-year shelf life ends.

High-Yield Capacity With Included Chip

The high-yield fill volume is the specification that determines whether this pack matches the planned print volume. Each cartridge is engineered to meet or exceed the original equipment requirement for page output. The installed chip ensures the printer reads supply levels correctly.

Questions about this item

How do I install the chip on the W2120X cartridge so the HP M554dn recognises it?

Remove the protective clip, align the cartridge rails with the printer slots, and push firmly until the chip clicks into the reader — skipping the clip removal is the step most users miss.

What maintenance will the four-colour high-yield set need after two years on the shelf?

The set carries a two-year shelf life; after that the toner may clump, so replace any cartridge that shows streaks or low-density output.

Which limit appears first during long print runs on the M578dn — heat or humidity?

The printer must stay between 10 °C and 30 °C; exceeding that range degrades print quality before the 80 % humidity ceiling becomes an issue.
