The MFP 10 captures an operation screen GA displayed by a browser BW on the touch panel 25 before a prescribed module program (firmware FW and browser BW, etc.) is changed. Further, the MFP 10 captures an operation screen GB displayed by the browser BW on the touch panel 25 after the prescribed module program is changed. Then, the MFP 10 detects an error state of the screen display on the touch panel 25 when the conformity between the operation screen GA and the operation screen GB is determined to be smaller than a prescribed level.</p> |
