If any change, which appears on a display for displaying the situation of the operation, is detected, it is judged whether or not an elapsed time, which elapses from the previous execution of the restoring operation for the discharge state of nozzles, exceeds a predetermined time period. If the elapsed time exceeds the predetermined time period, the control is made by a controller so that the restoring operation is executed for the recording head. The restoring operation is executed before the instruction of the recording operation for a recording medium in a multi function device which has various functions including, for example, the copy function, the facsimile function, the scanner function, and the printer function in combination and which is provided with the functions in a multifunctional manner. Therefore, the waiting time for a user, which is required until the completion of the recording, can be shortened.
