ABSTRACT:
A communication system for implementing maintenance of a copying machine is arranged to have one or more copying terminals, a host computer, and a communication line connecting both with each other. The copying terminal provides a counter for counting maintenance data such as a total number of copied sheets or jammed sheets, input keys, and a communication modem. The host computer provides a communication modem. The copying terminal has an operation unit for entering communication conditions such as a maintenance data transmission time by handling some input keys and a modem for sending the maintenance data to the host computer on the input data. The host computer also provides a standard timer for synchronously controlling the timers provided in the copying terminals so that the times indicated by all the timers are made equal.
