<P>PROBLEM TO BE SOLVED: To preliminarily and accurately respond to an event such as failure occurring on an operation in an image forming apparatus. <P>SOLUTION: When acquiring event occurrence arrival time information from other multifunctional machines 32 and 33 by an event occurrence arrival time information acquisition unit 1021, an adaptive information extraction unit 108 extracts event occurrence arrival time information in which performance information contained in the acquired event occurrence arrival time information and performance information stored in a performance information storage unit 1701 are matched with each other. A calculation unit 105 of a multifunctional machine 31 calculates a difference between time-course information, or a lapse time when the own multifunctional machine 31 performs a prescribed operation, calculated by a time-course information calculation unit 101, and the event occurrence arrival time information extracted by the adaptive information extraction unit 108 (S13). When a determination unit 106 determines that the difference reaches a predetermined limit value or less (YES in S14), a control unit 103 allows a display unit 150 to display a warning (S15). <P>COPYRIGHT: (C)2012,JPO&INPIT |
