An image forming apparatus, guide providing method thereof, cloud server and error analyzing method thereof are provided. The image forming apparatus may include a scanner configured to scan a script and generate a scan image, a communicator configured to communicate with a cloud server, a display configured display a screen, and a processor configured to control the communicator to transmit the generated scan image to a cloud server, and in response to receiving an error solution guide of the scan image from the cloud server, control the display to display the received error solution guide.

According to one embodiment, a maintenance system includes an image pickup unit and a control unit. The image pickup unit picks up images of respective regions of a target apparatus defined beforehand. The control unit acquires image data picked up by the image pickup unit and calculates parameters of the target apparatus on the basis of the image data.

An information processing system includes a storage unit that stores and associates a cause of a failure that has occurred in an electronic device, state information of the electronic device at the time the failure has occurred in the electronic device due to the cause of the failure, and a measure to be implemented in response to the cause of the failure. The information processing system further includes at least one processor that performs an acquisition process for acquiring the state information of the electronic device, and a failure diagnosis process for determining the cause of the failure that has occurred in the electronic device and the measure to be implemented in response to the cause of the failure based on the acquired state information of the electronic device.

A portable terminal device includes: a receiving unit that receives an action instruction in a predetermined action mode given by a user for one image processing device among a plurality of image processing devices; a radio wave strength detection unit that receives a radio wave for measuring the strength of the radio wave to detect the strength of radio wave of each of the image processing devices; a radio wave strength difference calculation unit that calculates differences in the strengths of radio waves between the image processing device with the maximum strength of radio wave and the other image processing devices; an identification unit that identifies, as the image processing device to which the action instruction received is given, the image processing device having the maximum strength of radio wave; and an instruction unit that gives the action instruction in the action mode to the image processing device.

A method of proactively identifying print device incidents for servicing by a service provider may include receiving print device data for one or more print devices, determining a probability value for each of the one or more of the print devices based on the print device data, where each probability value represents a likelihood that the print device will experience a subsequent incident of an incident type within a timeframe, identifying one or more of the print devices associated with probability values that each exceed a threshold value, and for one or more of the print devices that is identified, automatically initiating a service request for the subsequent incident.

A fax function diagnosis method and an apparatus for performing the method are provided. The fax function diagnosis method includes receiving a diagnosis request to diagnose a fax function of an image forming apparatus, diagnosing the fax function of the image forming apparatus by transmitting or receiving a test page, and performing an operation based on a result of the diagnosing.

An electronic device communicable with a server system via a network, includes circuitry to: transmit information on the electronic device to the server system; store in a memory information on a display component corresponding to the information on the electronic device that is acquired from the server system; read the information on the display component stored in the memory at a predetermined timing; display the display component that is read on a display; in response to selection of the display component, acquire information associated with the display component from the server system; and display the acquired information on the display.

An information distribution system includes an electronic device; and a server system including at least one information distribution apparatus that communicates with the electronic device via a network. The electronic device includes an information requester configured to transmit, to the server system, a request to distribute information, the request being transmitted together with identification information of the electronic device; and an information displayer configured to display, on a display device, the information transmitted from the server system. The server system includes a contract information acquirer configured to acquire contract information relating to a contract for a service provided to the electronic device; an information generator configured to identify the contract information of the electronic device based on the identification information, and generate the information according to the contract information; and an information distributor configured to distribute the information generated by the information generator, to the electronic device.

A monitoring apparatus determines a monitoring mode of a network device which is not registered in a central management apparatus based on capability information of the relevant network device and registers the relevant network device in the central management apparatus. When monitoring information is not yet transmitted from a network device of which a monitoring function is enabled to the central management apparatus or invalid, the central management apparatus is requested to start communication with the relevant network device. Based on a result of the communication, a registration state, communication information, and device information of the relevant network device managed by the monitoring apparatus are updated.
