A medium feeding device includes a medium placing portion, a feeding roller that feeds paper, a medium movement detecting portion that is positioned on a placing region of the paper of the medium placing portion in a medium feeding direction and is capable of detecting movement of the paper being fed in a width direction intersecting the medium feeding direction, and a controller that stops feeding of the paper in a case in which a physical quantity relating to movement of paper in the width direction exceeds a predetermined threshold based on a detected result by the medium movement detecting portion.

An image forming apparatus is provided. The image forming apparatus includes a print engine to be used to perform an image forming job, a motor to start the print engine, a driving circuit to supply a power to the motor and to include a sensor to sense a size of current of the power supplied to the motor during an operation to perform the image forming job, and a processor to detect an occurrence of jam based on a size of current sensed by the sensor in a first time interval while the motor is driven and a size of current sensed by the sensor after a determined time from the first time interval.

An image processing apparatus includes a display, a network interface, and a processor. The processor is configured to generate a first screen on which at least one malfunctioning part candidate of the apparatus is presented in a selectable manner, and control the interface to transmit error information corresponding to a selected malfunctioning part candidate to another apparatus. When a first malfunctioning part candidate corresponding to a particular sound output by the image processing apparatus that is not working properly is selected on the first screen, the processor generates a second screen on which one or more reference sounds potentially corresponding to the particular sound are presented in a selectable manner. When a reference sound is selected as corresponding to the particular sound on the second screen, the processor includes sound information corresponding to the selected reference sound in the error information.

Printing is performed based on a print job received from an information processing apparatus, the information processing apparatus is notified of a jam based on occurrence of the jam, and a reprint job for performing reprinting that is generated based on the notification of the jam is received from the information processing apparatus. A scanned image obtained by scanning a printed print product is transmitted to an inspection apparatus, and information indicating that an inspection result obtained by the inspection apparatus inspecting a quality of the print product is “fail” is received. Based on the reception of the information indicating the inspection result “fail”, the information processing apparatus is notified of a jam, and a reprint job for performing reprinting that is generated based on the notification of the jam is received from the information processing apparatus.

An image reading apparatus which is capable of preventing occurrence of a paper jam and poor stacking during conveyance of originals. The image reading apparatus sets a type of an original, conveys the original based on the set type of the original, and reads an image on the conveyed original. An original detecting sensor detects placement of the original on an original tray. An LCD touch panel displays an object for setting a type of the original in response to the detection by the original detecting sensor.

Provided is an image reading apparatus in which a setting screen is displayed upon detecting that a document is placed on the document tray. In a case where a document is placed on an automatic document conveyance device, if a paper jam occurs while using the automatic document conveyance device, a screen of a paper jam is preferentially displayed even when a setting of automatically displaying a selection screen of a sheet thickness is set at the time. This prevents a specific screen desired to be continuously displayed from being hidden upon detecting that a document is placed on a document tray.

An image processing apparatus includes a display device, a network interface, and a processor configured to generate a first screen for display on the display device and through which one or more potential errors of the image processing apparatus are selectable, and control the network interface to transmit error information for the selected error(s) to another apparatus. The errors include a first error type for which an abnormal noise is made by the image processing apparatus. The processor is further configured to, when the first error type is selected, generate a second screen for display on the display device and through which reference sounds potentially corresponding to the abnormal noise are selectable. When a reference sound is selected, sound information corresponding to the selected reference sound is included in the transmitted error information.

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 forming apparatus includes a display and a control device. The control device functions as: a detector detecting a trouble occurred in an own apparatus; and a controller. The controller performs, with respect to a trouble-displaying image including a two-dimensional code in which a storage location on a network is converted into an image, at least one of three outputs of displaying on the display, printing on a recording sheet, and transmitting to an external apparatus. The storage location is where information indicating a method for dealing with the trouble detected by the detector is stored. Based on a predetermined first degree using at least either difficulty in solving the trouble or seriousness of the trouble as an indicator, the controller changes a display color of the two-dimensional code corresponding to the trouble so as to be different as the first degree becomes higher.
