I had the problem. I removed and reinstalled the cartridge a cpouple times, turned the printer off and on a couple times, and the fault cleared and I was able to print again. I got this solution from a friend who had the same problem with an HP printer.

You get that message when the printhead goes bad. It's not the ink cartridges. You need a new printhead
