The HP 646 family is built around one idea: the black cartridge comes in high-yield by default. The 646X black (HP CE264X) pairs with the 646A color cartridges (HP CF031A through CF033A) to make the four-cartridge set — black plus the three color cartridges — for the Color LaserJet CP4025, CP4525, CP6015, and CM4540 machines. Note that HP lists the 647A black (CE260A) as an alternate for the CM4540 multifunction, so check your machine's label if you are unsure which black it expects. These are fleet printers, and fleets buy in volume — which is why cost per page matters more here than anywhere. Clever Supplies stocks both genuine OEM HP 646X/646A cartridges and compatible versions, letting procurement teams standardize on high-yield black across the whole printer pool.

Frequently Asked Questions

How do I tell 646X/646A apart from 647A/648A?

Check the part number on your installed cartridges: 646X black is CE264X, and the 646A colors are CF031A through CF033A. If your black reads CE260A, you need the 647A family instead. Both fit the same CP4025/CP4525/CP6015 printers.

Is the 646X high-yield black compatible with my 647A printer?

Yes — both black cartridges fit the same printers, so you can switch between 647A (CE260A) and 646X (CE264X) freely. The 646X simply holds more toner; it is an upgrade in yield, not a different fit.

Does the CM4540 take a different black cartridge?

HP lists the 647A black (CE260A) as the alternate black for the CM4540 multifunction, while the 646X (CE264X) is the standard high-yield. Either works — pick the 646X for maximum yield or the 647A to match what HP ships with the machine.
