After scanning a document my hp C4385 scanner/printer gives me the error message "incompatible ink cartridge". I've been using the ink cartridge without problem for several weeks. I've turned the printer off, disconnected the power supply, then restarted it. I've taken the print cartridges out and reinstalled them. I still get the same error message.
