Question about Printers & Copiers
HP photosmart 7960 has begun to print in light blue ink rather than normal black. Is the black cartridge bad? John Dalziel
Cartriges have a shelf life. It's printing in blue either because it has dried up or is out. Different cartriges have different timelines but if you haven't been using the printer often, it could have dried up or is simply out of ink. I would suggest first to try cleaning the head of the cartrige where the ink comes out with alcohol and a Q-tip and then if that doesn't work, buying a new black cartrige.

Place the ink cartridge print head on paper towel damp...if ink leaks out, your printhead is good.
If certain colour does not leak out..the nozzle has dried ink severely or the chamber is out of ink.
regular tape water.
If this is an inkjet with ink cartridge separate from the print head, check the due date on the cartridge.

This happened to me and I couldn't believe it. I only use brand new HP ink cartridges!!! I ran the cleaning diagnostic and still printed blue. Next I installed another brand new cartridge and ran the the alignment page. After that it worked fine. Not exactly sure what combination solved the problem, but now it works.

My problem was traced to the black ink tube being blocked up with dried ink (the printer had sat unused for a while). I solved the problem by using a thin wire and pushing it as far as it would go up the tube. That cleared the clog and solved the problem.
