I have a HP 722C printer that will only print black and magenta. It is supposed to print black, Magenta, yellow and cyan .
When it first happened I replaced the cartridge and the same thing happened. I then did a cleaning all the way through prime with the same results. I then returned the cartridge and got anothe one. Same results. I then uninstalled the driver and re-installed. Same results. I've had this printer since September 18, 1998 which came with my Dell computer. Dell doesn't warrant third party hardware and the HP warranty has run out. Does anyone have a suggestion?
