ABSTRACT:
A copying machine control system according to the present invention is a copying machine control system having a data terminal collecting data related to a copying machine and a centralized control station communicating data with the data terminal through a communication network, wherein the centralized control station includes a first communication terminal and a second communication terminal, and the data terminal includes a memory device for storing first and second calling data for calling the first and second communication terminals, respectively, a first calling device for calling the first communication terminal with the first calling data when a predetermined transmission condition is satisfied, a determining device for making a determination that connection can not be made to the first communication terminal in spite of operation of the first calling device, and a second calling device for calling the second communication terminal with the second calling data in response to an output of the determining device.
