Firmware updates render the printer to be unable to recognize refilled cartridges or compatible cartridges due to changes in the way the printer reads the non-original chip. New chips have been developed that work with the new firmware updates.
To avoid such issues, do not upgrade your firmware when the printer prompts you.
