I have a lexmark X4270 printer/fax machine. I replaced the black ink cartridge but the machine says "Black Cartridge Missing. I've tried reinstalling the old one and I get the same message. I tried cleaning them with a Q-tip, Turning the power off and on. I still get the same message, What do I do next?
