A "Supply Problem" message on the C720n often means the printer can't read one of the colour cartridges. Turn it off for 30 seconds, then reseat the cartridge for the colour being reported and gently clean its gold chip contacts with a dry cloth. When the warning keeps returning, install a new cartridge in the reported colour and the printer should recognise it.
