Enter the menu in "Ink Control" section. In "Empty Mode" settings, put it on "Stop". Then the printer will stop if it remains with no ink in one cartridge.

Of course, it's the possibility that the cyan cartridge had some problems and haven't "told" the printer that is empty. In this case....:signs101:
