GREENCYCLE C4129X High-Yield Toner

This GREENCYCLE C4129X black toner cartridge is an aftermarket replacement for the HP 29X original. It is built for offices running HP LaserJet 5000 or 5100 series printers that need a high-yield monochrome supply. The single pack delivers up to 10000 pages at .05 coverage. It suits buyers who want compatible performance without sourcing the OEM cartridge.

Replaces HP 29X C4129X cartridge

The cartridge replaces the HP 29X C4129X toner used in LaserJet 5000, 5000n, 5000dn, 5000gn, 5100, 5100tn and 5100dtn models. The jump is worth it when the original cartridge is unavailable or when a compatible high-yield unit lowers cost per page for the same rated yield. Buyers who need a MICR toner or a multi-pack bundle will not find those options here.

Consistent output across long print runs

The cartridge uses a smart chip, toner powder, smooth OPC and roller to maintain clear, crisp text and graphics over extended jobs. Print quality stays stable through the rated 10000 pages rather than fading after a short burst. Shaking the cartridge horizontally before install distributes toner evenly for reliable start-up. It is not suited for colour printing or for printers outside the listed LaserJet 5000 and 5100 families.

Questions about this item

Will the C4129X cartridge fit my HP LaserJet 5000dn without any adapter?

Yes — the C4129X is a direct replacement for the HP 29X cartridge used in the LaserJet 5000, 5000n, 5000dn and 5000gn, so it slides straight into the printer’s toner bay.

What is the one installation step people often miss with this cartridge?

After shaking the cartridge horizontally to distribute the toner, you must remove the transparent seal or orange plastic ring completely before inserting it; leaving any seal in place will block toner flow.

How many pages can I expect before the C4129X needs replacing?

The cartridge is rated for up to 10000 pages at 0.05 coverage on Letter paper; actual yield varies with graphics density and environmental conditions.
