Frequently Asked Questions

Which black cartridge does the M680z take?

This listing is the CF320X for the Color LaserJet MFP M680z — the high-yield black unit in the 653X family, rated at about 21,000 pages. The code on this box is the code to match against the cartridge already in the machine. It is $88.63 for the single cartridge.

Why pair a high-yield black with the M680z in particular?

The z model is the one fitted with finishing options, and it tends to run the longest unattended jobs — stapled report packs, booklets and batch mailings. Those runs are nearly all black text, so a 21,000-page black cartridge is what keeps a long finishing job from pausing for supplies.

Will the finisher keep working while toner runs low?

Finishing follows printing: once the machine decides black is too low to continue, stapled sets stop mid-batch. Keeping a cartridge with this much capacity in the slot — and a spare in the building — is the simplest way to protect end-of-month production runs.

Does scanning on the M680z use any of this toner?

No. Scanning and sending documents uses no toner at all. It is printing and walk-up copying that draw on the CF320X, which is why a scan-heavy office can still be surprised by how steadily a copy-heavy week consumes black.

How do I swap the cartridge between jobs?

Wait for the current job to clear, open the front door, slide the old unit out and the new one in, and close up. The machine recalibrates briefly and is ready for the next queue of work — no finisher settings are touched by a cartridge change.

What cover comes with this cartridge?

A 1-year warranty and free returns within that year, with the details on our shipping and returns page. We ship from warehouses in IL, PA, GA and CA, and support runs Monday through Friday, 9 AM to 5 PM CST.

What does the CF320X cost per rated page?

At $88.63 for a single cartridge rated at about 21,000 pages, the black supply works out to roughly 0.42 cents per page. Long finishing jobs are nearly all black text, so that figure is close to a true running cost for the M680z's staple work — a useful number when a department prices its report packs and batch mailings.

How should the spare be stored in a busy finishing room?

Sealed in its carton, indoors, somewhere it will not be buried under paper stock or knocked around by the finishing supplies. A cartridge rated at 21,000 pages may wait a long time between turns on this machine, and a spare that has lived quietly in its box prints at full density the day the installed unit finally gives out.

Should the spent cartridge be kept after the change?

Keep it until the fresh CF320X has cleared one complete stapled job without a fade or a stop. That first full run is the proof the new cartridge is healthy. After it, the spent unit has told you everything it can — it misled nobody, it simply ran out — and it can leave the room.

Is the black cartridge on its own ordering schedule?

Yes. The color cartridges for the M680z are stocked separately, each under its own part number, so the black slot is planned and reordered independently of the colors. That separation suits this machine: its long runs are black work, and the CF320X will usually need attention on a different rhythm from the color row beside it.

About This CF320X Cartridge for the M680z

The Color LaserJet MFP M680z is the hardest-working configuration in its family, and its black cartridge should match that workload. This compatible CF320X gives it a 21,000-page black supply in a single unit, bought on its own at $88.63. Color cartridges for the same machine are stocked separately in our HP listings, each under its own part number, so every slot can be ordered on its own schedule.
