Q: I have an HP All-In-One 7110. I put in a generic black ink cartridge a couple weeks ago. It never worked, everything came out blue and purple. So today I put in a real one, an HP one, but the black still isn't printing. I've aligned the printheads, cleaned the printheads, etc. Why isn't the black printing? When I put it on "black only," it comes out with barely any ink at all on the paper. All self-tests come back perfectly fine. Thank you. Ok, it's in the right place, and I reinstalled. Same problem, black comes out faded blue & purple. Man, I just shelled out $25 for this HP cartridge.
