This is where I start when looking at such. It lets me figure out where the problem is.

I have a Xerox M940 work center multifunction unit. I'v been working on a project and everything was fine. Today though, it won't print in color. I have tried printing, copying, and printing a test page. All cartridges have ink and are not dry. I cleaned the print heads, disconnected power and printer cables and re-attached, I re-booted the computer. The settings are set for color. I even pulled out the manual and it only says to check the settings. What else can I look for?
