My Photosmart C7280 All-in-One printer stopped printing yellow ink. I've replaced the cartridge twice and it still won't print yellow. I've reinstalled the complete HP Suite including driver with no success. I just installed HP Print and Scan Doctor - same result. Printer is 3 years old, not overworked, maintained regularly, and has worked flawlessly until now. Does anyone have any suggestions?
