<P>PROBLEM TO BE SOLVED: To reduce the possibility that, even if enabling a user to set settings of calibration that only a serviceman can set, the settings different from a result expected by the user are made to cause subsequent abnormality. <P>SOLUTION: When calibration settings in which an interval of executing calibration is set by the number of pages are made by a user through an operation unit 501 (S1207 and S1209), a CPU 1 of an image forming apparatus 10 controls to predict the time interval of executing the calibration on the basis of print history and the number of the pages set (S1211), allow the operation unit 501 to display the prediction result (S1212), and accept a user's instruction about whether to re-set the number of the pages, through the operation unit 501 (S1213). The image forming apparatus 10 allows the user to re-set the number of the pages corresponding to the interval of the calibration referring to the prediction result. <P>COPYRIGHT: (C)2013,JPO&INPIT |
