A control unit of an image reading apparatus acquires, at an upstream position in a medium transportation direction of an abnormality determination area set for a leading-edge area of a medium, a distance WL from a center position in a medium width direction intersecting with the medium transportation direction to one edge in the medium width direction and a distance WR from the center position to the other edge in the medium width direction, and compares a value R that is a ratio between the distance WL and the distance WR or a difference therebetween with a threshold R0 determined in advance.

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.

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.

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.

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 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.

An information processing apparatus includes: an extraction unit that extracts a document on which reading is unsuccessfully completed in a surface unit in a case where a bundle of a plurality of documents including written information are optically read one by one in order; and a generation unit that generates a list of summary results in which a number indicating in what number the document including a surface is read from the bundle of documents is added to a record corresponding to the surface on which reading is unsuccessfully completed.

An image forming apparatus includes processing circuitry; and a memory storing computer-executable instructions that cause the processing circuitry to perform printing onto a sheet; discharge the sheet onto which the printing has been performed; and control the sheet to be discharged in a manner such that a location of a paper jam can be identified among a plurality of sheets, upon detecting that the paper jam has occurred while printing onto the plurality of sheets.

A control unit of an image reading apparatus acquires, at an upstream position in a medium transportation direction of an abnormality determination area set for a leading-edge area of a medium, a distance WL from a center position in a medium width direction intersecting with the medium transportation direction to one edge in the medium width direction and a distance WR from the center position to the other edge in the medium width direction, and compares a value R that is a ratio between the distance WL and the distance WR or a difference therebetween with a threshold R0 determined in advance.

An image forming system including an image forming apparatus and portable terminals is provided. The image forming apparatus comprises a unit that detects an error as a cause of an interrupt of image formation and transmits an error occurrence notification to each terminal, and a unit that, upon receiving a recovery operation start notification from a terminal and determining that a recovery operation for the error is started, transmits the recovery operation start notification to each terminal. Each terminal comprises a user interface that, upon receiving the error occurrence notification, displays an error notification screen, transmits the recovery operation start notification to the image forming apparatus in accordance with an operation by a user, and upon receiving the recovery operation start notification from the image forming apparatus, displays a recovery operation start screen on the user interface unit.
