I've had this printer for about 2 years and yesterday I put a new color cartridge in which worked fine yesterdayl.  Today it won't print color at all.  I have wiped the bottom of the cartridge and it made the cloth inky so the problem's not there.  I notice that the ribbon cable is attached only to the black cartridge - should there be one attached to the color cartridge, too or is the connection internal?  Otherwise, I can't see anything wrong at all.  Can this be fixed or is it replacement time?
