content: My printer refuses to print yellow or black ink. Cyan and magenta work fine. I've replaced all of the cartridges, reseated them multiple times, ran it through its head cleaning cycle, and am using decent paper. It's like it's not even trying to print with those two inks. The driver is reporting the cartridges as present, the correct model, and full. If I print something that's just blue, it will print that. If I try to print something black it just shoots the paper through without even bothering to move the head. Printers are not my forte, and that's the extent of my troubleshooting knowledge. Any ideas?
