All of a sudden I can't print JPEGs in color from my MX870; but I can print text in color. The cartriges are full, and I unplugged the printer and restarted it, but the problem persists. I also have the current driver, so I'm stumped.
What version of Windows is installed on your computer?
If you are using a Mac, what version of OSX is installed?
What program are you using your print your images? Have you tried using Easy-PhotoPrint EX to print your photos?
