A system and method for paper jam prediction includes a processor, memory and a network interface. Ongoing paper jam data is received from an identified, networked multifunction peripheral. Service call data for the multifunction peripheral indicative of prior service calls is stored in the memory. A sampling window of the paper jam data prior to a service call date is defined and a point in the sampling window when no symptoms of a forthcoming paper jam were present is determined so as to define a prediction window. A relationship between paper jam data in the prediction window of the sampling window and paper jam data outside the prediction window in the sampling window is determined and incoming paper jam data is monitored relative to the relationship data. A paper jam warning is generated when monitored incoming paper jam data indicates a forthcoming paper jam on the multifunction peripheral.

A readout controlling device includes a start time recording portion, a transmission controlling portion, an error determining portion, and a time changing portion. A start time of when a piece of information is read out from a storage device connected to the readout controlling device is recorded in the start time recording portion. The transmission controlling portion transmits a readout request to read out the piece of information, toward the storage device based on the start time. The error determining portion receives the piece of information readout from the storage device, and determines whether or not an error has occurred in the piece of information. If the error has been determined to have occurred, the time changing portion can change the start time recorded in the start time recording portion.

The image forming apparatus includes a first control section and a second control section. The first control section includes first nonvolatile memory having a log saving area and, upon occurrence of an error, acquires an error log and saves the error log into the log saving area. The second control section includes second nonvolatile memory for storing second software therein and, upon occurrence of an internal communication error causing an interruption of communications with the first control section, the second control section erases the second software and saves in the second nonvolatile memory a communication error log necessary for analysis of the internal communication error.

An apparatus includes circuitry to receive an input of problem information that is information on a problem, transmit the problem information to an information processing apparatus communicably connected to the apparatus via a network, and receive, from the information processing apparatus, troubleshooting information corresponding to the problem information. The troubleshooting information is information for solving the problem. The circuitry outputs the troubleshooting information, and transmits, to an extraneous resource, a repair request including the problem information and information indicating whether the troubleshooting information has been output.

An image processing apparatus receives, via a user interface setting screen, a designation to determine a specification of RFC used to return a value indicating a status of the image processing apparatus in response to a request from a host. A control unit of the image processing apparatus returns the value indicating the status conforming to a specification determined according to the designation in response to a request issued at the predetermined time interval from the host. The control unit further returns the value indicating the status conforming to a specification determined according to the designation in response to a request issued at a time interval shorter than the predetermined time interval from the host in a case where it is determined by the host that the former returned value indicates an abnormal state of the image processing apparatus.

A communication device includes a first holding unit which holds a disk-like first recording medium capable of storing information and a second holding unit which holds a second recording medium which is different from the first recording medium. The communication device further includes a request reception unit configured to receive a request for information indicating a recording medium which is usable by the communication device from a terminal device, and a transmission unit configured to transmit information indicating the first recording medium and information indicating the second recording medium held by the second holding unit to the terminal device when the request is received.

A communication device includes a hardware processor that: acquires error history information including a communication condition at a time when an error has occurred in past data communication between the communication device and an external device group and type information of the error in the past data communication; compares, in new data communication between the communication device and one external device, a first communication condition with a second communication condition; starts acquisition processing of a communication packet group related to the new data communication on condition that contents of both of the communication conditions with respect to at least one predetermined item are determined to be the same; and stores the communication packet group in a predetermined storage on condition that an error of a type same as an error type of the one error included in the error history information has occurred in the new data communication.

The present invention directs to an image processing apparatus comprising: a plurality of units each holding individual operation logs; a memory device that stores a set of instructions; and at least one processor that executes the set of instructions to: detect an error that has occurred in the image processing apparatus; determine the type of the detected error; decide a unit which obtains operation logs from among the plurality of units and an order in which the operation logs are obtained, in accordance with the determined type of the error, and based on the decided unit and order, obtain the operation logs from the decided unit and store the operation logs in a non-volatile memory.

A readout controlling device includes a start time recording portion, a transmission controlling portion, an error determining portion, and a time changing portion. A start time of when a piece of information is read out from a storage device connected to the readout controlling device is recorded in the start time recording portion. The transmission controlling portion transmits a readout request to read out the piece of information, toward the storage device based on the start time. The error determining portion receives the piece of information readout from the storage device, and determines whether or not an error has occurred in the piece of information. If the error has been determined to have occurred, the time changing portion can change the start time recorded in the start time recording portion.

The automatic document feeder includes a multi-feed detection sensor unit, a sensor control unit, and a control board on which the sensor control unit is mounted. The multi-feed detection sensor unit includes a transmission board on which a transmission sensor and a detection circuit of a drive current of the transmission sensor are mounted, a reception board on which a reception sensor and an amplifier circuit of a reception signal of the reception sensor are mounted, and a relay board on which a drive circuit of the transmission sensor is mounted. The sensor control unit stores first fault information indicating that the relay board is disconnected if the relay board is disconnected, stores second fault information indicating that the reception board is at fault if an output value of the amplifier circuit is equal to or less than a first threshold, stores third fault information indicating that the transmission board is at fault if the detection circuit does not detect the drive current, and stores fourth fault information indicating that the transmission sensor or the reception sensor is damaged if the output value of the amplifier circuit is equal to or less than a second threshold. If the fault information is stored, the sensor control unit transmits, to an image forming apparatus, an instruction signal for causing the fault information to be displayed.
