Color LaserJet CM6040 MFP

HP aimed the Color LaserJet CM6040 MFP squarely at high-volume offices: a 2008-era color multifunction whose print, scan and copy unit was built to be the department's default destination. Its cartridges are the 823A-824A family — compatible black CB380A, cyan CB381A, yellow CB382A and magenta CB383A. HP documentation for the model names CB390A as the original black; the compatible black stocked on this shelf is the CB380A, so take your black from the listing below.

The step up from the CM6030 in the same generation, the CM6040 MFP was specced for floors where the printer queue is a shared resource and downtime is measured in other people's missed deadlines. Everything about feeding it follows from that role: bigger shared workload, faster black consumption, and a supplies shelf that has to be right before it has to be cheap.

Toner Cartridges for Color LaserJet CM6040 MFP

Which cartridge should you buy?

Plan purchases around service moments. When the machine is opened for one cartridge, check the other three levels: if two or more sit low, the 823A-824A 4-color set or the premium 4-color set turns four future interruptions into one. When only a single level has fallen, a single is the honest buy — black for the document queue, or whichever color a long graphics run has drained. The model-named set in the table is the same four codes under this machine's own name. Every compatible here is backed by a 1-year warranty and 1-year returns, which matters on a machine whose cartridges are bought by the case, not the occasion.

Chip, toner and everyday use

Paper path and toner path meet inside this machine, so keep both clean: a sheet that lodges behind a cartridge can mimic a print-quality fault. When changing cartridges, work through the front door, pull the old unit straight out, and slide the new one home until it clicks; then let the calibration cycle complete before printing. If the machine questions a fresh cartridge, reseat it and inspect the chip contacts rather than forcing anything. Remember that yields are calculated at roughly 5 percent coverage — the dense, logo-heavy pages a marketing or HR floor produces will always finish a cartridge sooner than the rating implies.

Frequently Asked Questions

What toner cartridges does the Color LaserJet CM6040 MFP use?

Four separate cartridges from the 823A-824A family: CB380A black, CB381A cyan, CB382A yellow and CB383A magenta in the compatible range here. HP's documentation also names CB390A as the model's original black code; the compatible black on this shelf is the CB380A.

How do I clear a paper jam in the CM6040 MFP?

Switch the machine off, open the covers, and pull the jammed sheet gently in the direction of the paper path — never sideways, which tears it. Check behind the toner cartridges as well, since a sheet can lodge there, then reload with fresh, fanned paper.

Should I replace all four cartridges at once?

Only when the levels genuinely fall together. Each cartridge runs down independently, so the default is to swap the one the printer flags; replacing the set early discards the toner remaining in the healthy three.

Why does black run out so much faster than the colors?

Because most office output is text. Even color documents are mostly black words on a white page, so the black cartridge does the majority of the work while the colors contribute accents — which is why the black spare matters most on this machine.
