I've got this problem in which my printer prints a picture the correct color at first, but it has the banding (vertical lines) issue in which it looks really bad. Then, after the inital print, everything starts printing the wrong color. Reds are printed as a light lime green. I've tried re-installing the HP software, I've cleaned the cartridges both by hand and through software, and I've done the alignment. Both my color cartridge and my black cartridge are plenty full. Color is about half way up via software check, and black is about a 1/4 full. What's the problem, and how can I fix it? Thanks. EDIT: Oh yeah, I've also tried printing through different programs, including photoshop, iPhoto, and Image Preview. And I've tried different pics from different sources.
