HP Color LaserJet 4600 Toner Cartridges

Color LaserJet 4600

When the Color LaserJet 4600 arrived it marked a genuine leap in color laser quality, and design-conscious offices noticed the richer, more accurate output immediately. It runs on the 641A family — black (C9720A), cyan C9721A, yellow C9722A and magenta C9723A — four separate cartridges, each on its own replacement cycle. For the positions that work hardest there are longer-running builds: 641X black (C9720X), plus yellow C9722X and magenta C9723X. Compatible and genuine OEM cartridges are both stocked for the 4600.

This was the machine that moved color laser printing from a specialist corner into ordinary departmental work — presentations, reports and client documents in full color, printed in-house. That workload shapes its supply pattern: black carries the document load, while yellow and magenta carry the graphics. Owning a 4600 today usually means feeding a proven engine that still earns its floor space, and its appetite is predictable once you watch which colors your own work consumes fastest.

Which cartridge should you buy?

Buy against the way your colors actually deplete. Black usually turns over first, so the 641X black earns its keep on text-heavy machines, while the standard black suits lighter mixed work. Yellow and magenta are the colors busy offices burn fastest, and both exist in longer-running 641X form; cyan stays standard-yield only in this family. When three or four slots are low at once, a four-color set is the tidy option and keeps all four cartridges the same age. Compatible cartridges here carry a 1-year warranty and 1-year returns; genuine HP suits buyers who must stay OEM. Always order by the C972 codes.

Chip, toner and everyday use

The printer reads a chip on each cartridge at installation, so push a new cartridge in until it seats with a positive click and allow the recognition cycle to complete. A color that prints light before its time often just needs its toner redistributed: lift that cartridge out, rock it gently from side to side, and refit it. Remember that rated yields assume five percent coverage, and full-color pages use toner far faster. Store spares sealed and flat, away from heat and bright light, and fit the oldest spare first so stock never ages out on the shelf.

Frequently Asked Questions

Which toner cartridges fit this printer?

The HP 641A family: black C9720A, cyan C9721A, yellow C9722A and magenta C9723A. Extended-yield 641X versions exist for black (C9720X), yellow (C9722X) and magenta (C9723X); there is no 641X cyan.

Can I change only the color that ran out?

Yes — the four cartridges are independent. Swap the empty color on its own and leave the rest in place; the printer keeps working with the remaining cartridges untouched.

Will cartridges listed for the sister models fit my machine?

The 4600 and 4650 lines share the 641A family, which is why listings named for the sister models appear on this shelf. What matters is the cartridge code: if it is a C972 code from the family above, it is the right cartridge regardless of the model name on the listing.

My printer says a new cartridge is not recognized. What should I check?

Remove the cartridge and reseat it firmly, confirm the code on the box matches the slot you are filling, and let the printer complete its start-up cycle. A correctly coded, well-seated cartridge is recognized without any settings change.
