Abstract: A supervising system for image forming apparatus includes a central control apparatus, a public communication network connected to the central control apparatus, a communication adaptor connected to the public communication network, and a plurality of image forming apparatus connected to the communication adaptor via a wired or a wireless interface. The supervising system further includes a mobile computer selectively connected to the wired or wireless interface directly or indirectly for executing communications of information between the central control apparatus and itself via the public communication network.

Abstract: An image forming apparatus supervisory system includes a central supervisory apparatus that remotely supervises a plurality of image forming apparatuses installed in a plurality of user sides. A plurality of communications adapters are provided to connect to the central supervisory apparatus by a communication line. A plurality of interfaces are provided to connect each of the plurality of image forming apparatuses with each of the plurality of communications adapters. A firmware download device is provided in the central supervisory apparatus to remotely download prescribed updated firmware to an applicable one or more image forming apparatuses in accordance with updated hardware thereof. A hardware update device is provided to update the hardware.

Abstract: A remote diagnosis system includes a central computer system that receives user data related to a user request and deals with the user request data, and at least one kind of image-forming apparatus connected to the central computer system. Each image-forming apparatus has a user request data input device, through which data related to a user request is optionally input, and a user request data transmitting device that transmits the user request data to the central computer system. A data communication adapter collects the user request data from the at least one kind image forming apparatus and transmits the user request data to the central computer system. An interface interfaces the at least one kind of image-forming apparatus with the data communication adapter, and a public communication network connects the data communication adapter with the central computer system.
