LaserJet Enterprise M651n

LaserJet Enterprise M651n printer

The N in LaserJet Enterprise M651n stands for built-in networking — this is the shared color printer a small office plugs in once and then simply uses. Its cartridge family is CF320A black or the high-yield CF330X, with CF331A cyan and CF332A yellow alongside — and the member stocked on this page is the magenta, CF333A (654A). The black, cyan and yellow members of the family are not stocked here.

What keeps this model in service is unglamorous reliability at everyday office document printing — letters, invoices, the occasional color report — shared across a handful of desks through its Ethernet connection. Its cartridges are shared with the other models in the family list below, which keeps supplies easy to find and lets an office standardize its toner shelf instead of stocking something different for every machine.

The rest of the family — CF320A standard black, CF330X high-yield black, CF331A cyan and CF332A yellow — fits this printer as well, but those cartridges are not stocked on this page; only the magenta is sold here.

Which cartridge should you buy?

If the M651n is telling you magenta is low, the CF333A above is the whole answer — each color on this printer is a separate cartridge, tracked on its own, and only the empty one needs to change. That one-at-a-time design is the economical way to run a color laser: you never throw away remaining toner in the colors that still have life. A small office that prints color regularly will save itself a stall by keeping one magenta spare in the drawer, since a shared printer with one empty color can hold up everyone's black-and-white work too.

Chip, toner and everyday use

Levels for all four cartridges can be checked without walking to the machine — the printer software on any connected workstation shows them, which suits a shared device. When a new cartridge goes in, remove all of its packaging and sealing tape and seat it firmly; the chip on the cartridge is what the printer reads to report its level, and a clean, fully seated fit keeps those readings honest. Store the spare upright, sealed and out of direct sunlight.

Frequently Asked Questions

Which toner cartridges does the LaserJet Enterprise M651n use?

The family is CF320A (black), CF330X (black high-yield), CF331A (cyan), CF332A (yellow) and CF333A (magenta), each a separate cartridge that the printer tracks independently. This page stocks the CF333A magenta; replace only the color that runs out.

Can the M651n be shared on an office network?

Yes. Its Ethernet connection lets you plug it into the office network and install the driver on each workstation, after which every computer sends jobs directly to it. That is the normal way this model is deployed — one machine, several desks.

Can the M651n still print in black if a color cartridge is empty?

Often not: many color lasers pause when any cartridge is empty, and this one may block printing until the depleted color is replaced. Keeping a spare from the CF320A/CF330X/CF331A/CF332A/CF333A set on hand means one empty color never stalls a black-and-white job for the whole office.
