ABSTRACT:
A control system for collectively supervising a plurality of copiers or similar image forming apparatuses connected to a control device by communication lines with or without the intermediary of communication control units. To down-load data relating to image formation, the control device determines whether or not a copier of interest is an inoperative state and, if it is in an inoperative state, automatically sends the data to the copier via a telephone line, an exchange, and a communication control unit. This data is written to storing means built in the copier. To up-load data relating to image formation, the control device causes each copier to automatically send the data stored in the storing means thereof and stores the data in memory means thereof. Up-loading is effected at an optimal time other than the time when the copier is performing an automatic adjustment, in use, or quite likely to be used.
