I've had a printer for a while now, an HP Deskjet 5700 Series. Its worked fine for the past year and a half, and then one day came up with an error message saying that I have the incorrect cartridge for the color cartridge. I know its the right one, and I've taken them out and cleaned everything, even replaced the cartridge, yet I still get the same error. I've talked to HP about this and all they can tell me is to uninstall and reinstall the software for it, which I did, to no avail. Even when the printer is unplugged from any computer, the color cartridge light is still flashing, telling me something is wrong with it. Any help would really be appreciated!
