Recently I bought a new black toner Q6000 cartridge for my hp color laser jet printer. It worked fine at first, but now it will only print a page that is solid black. What should I do?

Several websites suggest that the most likely cause of an all-black page is a damaged primary corona wire.

If it's an HP cartridge, contact HP. They should be able to replace it for you.

This could indicate a problem with your fuser unit, or the photo conductive unit. Look at the care guide (or download one) and perform a full maintenance on your printer as it may be possible just to clean it without purchasing a new one
