An image processing apparatus capable of preventing display priority of an application button displayed on a home screen from being raised to a higher rank due to repeat of error termination. A plurality of application buttons each for executing a predetermined job with settings therefor are displayed on the home screen. A user interface selects one object of the plurality of objects. After the one object is selected by the user interface, the one job is executed based on settings set in association therewith. When execution of the job is not normally completed, the controller does not increase the number of times of use of the object selected by the user interface according to which the display priority of the object is raised.

An image forming apparatus includes a CPU. When an error occurs, the CPU notifies a user or the like of the error and adds information about the error to an error table. When the error is resolved, the CPU deletes the information about the resolved error from the error table. The CPU refers to the error table and displays, on a display, a home screen in which a badge indicating the number of unresolved errors in each operation mode is displayed. When a mode selection button on which the badge is displayed is touched, the CPU re-notifies the user of the unresolved errors.

An image processing apparatus includes a processing section and a control section configured to instruct operation of the processing section. The control section executes, before sending, to the processing section, a first instruction corresponding to an instruction that caused an error in the past, an error avoidance operation based on instruction history information and operation state history information acquired from a storing section that stores the instruction history information and the operation state history information, the instruction history information indicating an instruction given to the processing section by the control section, the operation state history information indicating an operation state of the processing section caused by the instruction.

A non-transitory storage medium stores a plurality of instructions readable by a computer of an information processing apparatus. The information processing apparatus comprises a communication interface for connecting to a scanner. The information processing apparatus includes a first route and a second route. When executed by the computer, the plurality of instructions cause the information processing apparatus to execute a scan control using the first route in which a read result of a document by the scanner is obtained by using the first route after receiving an execution instruction for scanning, determine whether the scan control using the first route has failed or not, and execute a scan control using the second route in which the read result of the document by the scanner is obtained by using the second route when it is determined that the scan control using the first route has failed.

A printing device, comprising a frame, an image-forming module, a non-volatile memory (NVM), a control operatively arranged to read the NVM incidental to controlling the printing device, and a first tag connected to the frame, the first tag holding information relating to a configuration of the printing device.

A maintenance support device includes a memory that stores work result information that corresponds to a maintenance work that has been performed to solve a failure of an image processing apparatus. A processor is configured to acquire, and store in the memory, first work result information corresponding to a first maintenance work performed to solve a first failure type. After the first work result has been stored, the processor acquires, and stores in the memory, second work result information corresponding to a second maintenance work performed to solve a second failure type. It is then determined whether the first failure type matches the second failure type. Upon determining that the first and second failure types match, the first work result information is then updated to indicate that the first maintenance work has not been successful.

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.

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.

An image forming apparatus includes a CPU. When an error occurs, the CPU notifies a user or the like of the error and adds information about the error to an error table. When the error is resolved, the CPU deletes the information about the resolved error from the error table. The CPU refers to the error table and displays, on a display, a home screen in which a badge indicating the number of unresolved errors in each operation mode is displayed. When a mode selection button on which the badge is displayed is touched, the CPU re-notifies the user of the unresolved errors.

Methods and apparatus for recording and indicating events associated with printing devices are provided. A computing device can receive a request to record information about a printing device. The request can specify a plurality of types of information related to a time-oriented sequence of events associated with the printing device. After receiving the request, the computing device can record the specified plurality of types of information related to the time-oriented sequence of events. The computing device can indicate the time-oriented sequence of events associated with the printing device using the recorded plurality of types of information.
