Abstract: An image forming device management system includes a plurality of image forming devices, a central service station which provides a maintenance service for the image forming devices, and a communication control unit which is connected to each of the image forming devices by a signal line, the communication control unit connecting one of the image forming devices to the central service station via a communication network. In the system, each of the image forming devices includes a message unit which outputs a signal line separation message when the image forming device has no signal from the central service station or the communication control unit over a predetermined period.

Abstract: A recycling system has a recycle information memory database for storing as recycle information, the information on all reutilizable products such as products produced or used under the management of the system, products treated as wastes, and products currently being used in the market. A virtual recycle product designing section is provided for estimating times when the reutilizable products are recovered as products usable for recycling as well as their volumes, based on the recycle information stored in the recycle information memory database. A production scheduling section is provided for setting a production schedule of a recycle product using the reutilizable products based on the estimated times and volumes.

Abstract: A remote diagnosis system including a plurality of image forming apparatus each having a trouble informing device, and a central controller for receiving data including a trouble indicator indicative of a problem which may or has occurred in each of the image forming apparatus and for responding to this data. Also included is a data communication apparatus, connected to each of the plurality of image forming apparatus and the central controller, for receiving the data including the trouble indicator from each of the plurality of image forming apparatus, and for transmitting this data to the central controller. The remote diagnosis system further includes a trouble classifying device for classifying causes of trouble which may occur in each of the image forming apparatus. In addition, the data communication apparatus collects data classified by the classifying device.

Abstract: An image forming apparatus administration system includes an image forming apparatus for forming an image on a sheet of paper. A service terminal is connected to the image forming apparatus through a communication line and administers conditions of the image forming apparatus. An operation panel has operation keys and a screen. A changing device can be operated to change an indication of the operation panel from an indication for inputting an operation command for image formation to an indication for inputting a request command for transmitting data from the image forming apparatus to the service terminal. A transmitting device can transmit the data in response to the request command and the changing device changes the indication of the operation panel from the indication for inputting a request command for transmitting data from the image forming apparatus to the service terminal to the indication for inputting an operation command for image formation before the transmission of the data is completed.
