For any severe cartridge error related message, on the HP C4600, C4700 or D110a printer models, I suggest you run the internal Tap 41 diagnostics test which will tell you the electrical health of the ink cartridge - in many cases the cartridge is internally electrically damaged and will need to be replaced. In addition, you can temporarily bypass an 'incompatible cartridge(s) or Missing/Not Detected error message by performing the Cartridge Error Bypass procedure...refer to two Youtube videos on how to do this:
