GREENCYCLE C4129X 2-Pack Compatible Toner

This two-pack supplies black toner cartridges built to replace the HP 29X C4129X original. Each unit targets approximately 10000 pages at .05 coverage on Letter paper. It suits offices running Laser Jet 5000 or 5100 series printers that need a lower-cost supply option.

Printer model and cartridge slot check

Confirm the exact printer model matches the listed Laser Jet 5000 or 5100 variants before ordering. Verify the machine accepts the C4129X form factor and that the smart chip communicates with your firmware. Ensure the cartridge bay is free of debris from previous cartridges.

Consistent output during long print runs

The multi-layer sealed packaging protects toner integrity during storage so the powder stays free-flowing. Shaking each cartridge horizontally before install distributes toner evenly across the roller. The smart chip maintains stable communication through high-volume jobs without triggering false empty warnings.

Questions about this item

Does the package contain two complete cartridges or do I need to buy a drum unit separately?

The box includes two complete C4129X black toner cartridges; no separate drum unit is required for the listed LaserJet 5000 or 5100 printers.

Why is this listed as a 2-pack instead of a single cartridge?

The 2-pack supplies two 10000-page black cartridges in one purchase, lowering the cost per cartridge for offices that print high volumes on LaserJet 5000 or 5100 models.

Will I really get 10000 pages from each cartridge in daily use?

The 10000-page figure is measured at 5 % coverage on Letter paper; pages with dense graphics or smaller fonts will reduce the actual yield per cartridge.
