Hi
check the paper settings on the printer and also on your computer they must match e.g A4 on both

This is what worked (so far) with my Dell AIO A940 printer that wouldn't print black ink.

It worked for awhile when I chose photo/glossy paper, but then it quit printing again (see below).

PRINT, PROPERTIES, PAPER SETUP, SPECIALTY PAPER, PHOTO/GLOSSY


I got it to print, again, by putting SEVERAL papers in the feeder (instead of just 1) - there is a sensor that is supposed to automatically detect paper type, and it might not be working right, especially with one or only a couple of sheets.

Turn the darn thing over and shake it. there's probably something in there. In mine it was a miniature oyster cracker. Works great now but I was about to go insane until i shook it out.
