System for remote diagnosis of image forming apparatuses, including intelligent communications control for data therefrom
First Claim
1. The remote diagnosis apparatus having centralized control, the apparatus comprising:
- a communication line for carrying data;
at least one image forming apparatus;
at least one communication controller connected to said image forming apparatus for receiving and storing particular data sent from said image forming apparatus and executing communication control by accessing said communication line and completing a call to a data controller over said communication line for forwarding said particular data to said data controller; and
wherein said data controller is connected to the communication line and includes an access portion permitting said data controller to access said communication controller over said communication line, said communication controller receiving control data from said data controller and processing it into a form for local communication control or for sending to the image forming apparatus for image forming apparatus control, said communication controller providing said data controller with response data indicating the completion of control processing over said communication line.
