Thanks for the suggestion. I tried it, but no luck. After much fiddling around,I was able to override the error by going to the HP Director controls and printing my (black and white) image as a "color" picture. That told me it was the black cartridge that was being rejected, so I finally had to just give up and buy a new one, although there was no obvious problem with the old one. I had tried cleaning it, and it had just been used a day or two earlier and was not low on ink or clogged!
