[OMKAR2242]

I have office jet pro 9720 printer. Today i remove my printer's cartridge to clean the printer from inside but when i put it back into printer it shows an error showing that you are using continuous ink system. I have pre installed HP 938 series setup cartridge into my printer and also my printer is in warrenty. I want proper solution for this and i am not spending any money on it. It is just 5 months i bought the printer and this issue occured. In hp smart it shows that you are using continuous ink system. Please resolve my query asap.
