4 year old printer has been humming along just fine -- I like it, it has worked well for what I do. I like the camera card reader slots.

I print most things in grayscale or black ink only modes.

Today I printed out several copies of a page in "black ink only" mode and the first one came out OK, the next several had white lines and poorer quality, getting worse until the last one had no printing on it at all. Assuming I had emptied the cartridge, I refilled it (something I have done often without trouble). No printing. So I broke open a new one, assuming this one had been damaged. No change.

I have cleaned the cartridge contacts, the print head, done self-tests, and had it clean the head itself. It still won't print... it goes through the motions, so it thinks it is printing. It asks for allignment when I changed cartridges, etc., and I do that each time.

I printed something in dark blue, and it came out blue blue -- no black ink was added. So it prints in color, as long as the colors don't need any black added (which most do). Obviously it's a black ink problem so I don't think it has completely died on me.

Is something clogged that I haven't discovered yet? But same results with a refilled cartridge and a new (altho not HP brand) ink cartridge.
