GREENCYCLE 29X Black Toner Cartridge 10 Pack

Ten-Pack Black Toner for HP 29X Printers

This ten-pack of GREENCYCLE 29X black toner cartridges replaces the HP C4129X original. It fits LaserJet 5000, 5000n, 5000dn, 5000gn, 5100, 5100tn and 5100dtn printers. Offices with several compatible machines can standardise on one supply. Buyers who need colour output or a different cartridge model cannot use this pack.

Yield Measured at Five Percent Coverage

Each cartridge is rated for approximately 10000 pages at .05 coverage on Letter paper. Real-world yield drops when pages contain dense graphics, heavy bold text or full-page solids. The printer does not track toner weight, so the low-toner warning relies on the smart chip estimate. Users who print high-coverage documents will replace cartridges more often than the rated figure suggests.

Smart Chip and Sealed Packaging

A smart chip on each cartridge communicates with the printer for supply-level reporting and compatibility checks. Multi-layer sealed packaging protects the toner powder, OPC drum and roller from humidity and shock during storage. Cartridges must be shaken horizontally before the seal ring is removed and the unit is installed. Buyers who prefer original HP supplies or require a manufacturer-backed warranty programme will choose a different source.
