ABSTRACT:
A control apparatus according to the present invention is a control apparatus collecting data about copying machines and communicating with a centralized control unit on the basis of the collected data, including a detection device for detecting trouble occurrence on the basis of the data from the copying machines, a counter for counting the number of times the trouble occurrence in response to an output of the detection device, a calculating device for calculating a trouble occurrence frequency on the basis of the number of times of trouble occurrence while the copying machine performs copying operation for a predetermined number of times, a determination device for determining that the trouble occurrence frequency calculated by the calculating device exceeds a predetermined value, and a communication device for calling the centralized control device in response to an output of the determining device.
