Color LaserJet CM6040
The Color LaserJet CM6040 is the 2008-era color MFP built for high-volume offices — print, scan and copy from a departmental machine designed for steady throughput. Its toner is HP's 825A black (CB390A) plus the 824A colors, and for the black slot our compatible range supplies the 823A (CB380A) cartridge cross-listed for the CM6040 alongside those colors.
One cartridge family keeps the whole MFP printing, which is a genuine operational virtue in a department: whoever manages supplies learns four codes, stocks four codes, and never has to ask which of several toner lines a given job needs. On a machine that scans and copies as much as it prints, that simplicity compounds quietly over years of service.

Which cartridge should you buy?
Because a departmental MFP consumes black fastest, the black cartridge is where the money decision lives: genuine CB390A for the exact OEM formulation, or the compatible CB380A when the month's volume makes the saving matter more — on this class of machine it adds up quickly. The colors (CB381A cyan, CB382A yellow, CB383A magenta) should be stocked as singles and replaced individually; a department rarely drains all three together. The four-color sets on this page are for a full refresh. Compatibles here carry a 1-year warranty and 1-year returns.
Chip, toner and everyday use
When the CM6040 prints faded or streaked pages, work the simple checks in order: confirm on the supplies menu that none of the four cartridges is low, run a cleaning page from the device menus, and if streaks persist, take out the suspect cartridge, rock it gently to redistribute the toner, and reseat it. A cartridge that has sat half-used through a quiet quarter often just needs that redistribution before it prints evenly again. Store the next set flat, sealed and away from direct light.
Frequently Asked Questions
What toner does the Color LaserJet CM6040 take?
It needs all four cartridges of the family installed: CB390A black in genuine form — covered compatibly by the CB380A on this page — plus CB381A, CB382A and CB383A in cyan, yellow and magenta. Sets marketed as replacements for those exact codes will work.
Can the Color LaserJet CM6040 scan and copy as well as print?
Yes. It is a multifunction machine, so print, scan and copy all run from the same unit, using the scanner glass or the automatic document feeder at the control panel.
Why is my Color LaserJet CM6040 printing faded or streaked pages?
Start with the supplies menu to confirm no cartridge is low, then run a cleaning page from the device menus. If streaks persist, remove the suspect cartridge, rock it gently to redistribute the toner, and reseat it.
Should a department keep spare cartridges for the CM6040 on site?
It is the cheapest insurance the model offers. A stalled departmental MFP idles everyone queued behind it, while a spare black and one of each color take up a single shelf.
