An image forming system includes an image forming apparatus and a mobile terminal. The mobile terminal communicates with the image forming apparatus through a communication network. Mode information is inputted to the image forming apparatus from an external device. The mode information indicates one mode among a quiet mode in which an image is formed at a predetermined formation speed, a normal mode in which the image is formed at a faster formation speed than the quiet mode, and an urgent mode in which an image forming process in the quiet mode or the normal mode is interrupted to form the image. The quiet mode is sellable on the mobile terminal. The image forming apparatus forms the image in the urgent mode when the mode information inputted from the external device indicates the urgent mode and setting information indicating the quiet mode is acquired from the mobile terminal.

A recording apparatus (100) which records content in a recording medium (113 and 114) includes an obtaining unit which obtains information on a temperature of the recording medium (S311) and a display controller which performs control such that display associated with the temperature of the recording medium is performed based on the temperature information obtained by the obtaining unit (S314).

An image forming apparatus includes an apparatus body, a sheet stacking portion on which a sheet discharged from the apparatus body is to be stacked, an extension member, and an upper device. The extension member is rotatable about a rotating fulcrum between a first position at which the extension member is stored in the sheet stacking portion and a second position at which the extension member extends to downstream of the sheet stacking portion in a sheet discharge direction in which the sheet is discharged from the apparatus body. The upper device is disposed above the rotating fulcrum of the extension member and is supported to be openable by the apparatus body. The upper device in a closed state regulates a rotation of the extension member from the first position toward the second position.

An image reading apparatus includes a scanner, a sensor, and a controller. The sensor is configured to detect an original at a predetermined position. The controller is configured to determine whether or not an immediate execution mode in which no user operation is needed to cause the scanner to start scanning is set, and in case the immediate execution mode is determined to be set, determine whether or not a scan start condition is satisfied. The scan start condition includes the sensor detecting the original at the predetermined position. The controller is configured to control the scanner to start scanning, upon a standby time of a predetermined amount being passed since the scan start condition is satisfied.

An image reader wherein a controller executes: a start process of starting a reading operation; a head edge detection process of detecting a document width; a first side edge detection process of detecting a side edge until an occurrence of a first change from a side edge detecting state to a side edge non-detecting state; a calculation process of calculating a continuation distance based on the document width; a second side edge detection process of detecting the side edge until an occurrence of a second change from the non-detecting state to the detecting state; a third side edge detection process of detecting the side edge until an occurrence of the first change; and an end process of ending the reading operation when the second change does not occur in a continuation range in the second detection process or when the first change occurs in the third detection process.

An image processing apparatus includes: a memory configured to store a machine-learned model produced by performing machine learning using teaching data associating image data generated by reading a document by an image reading device with device abnormality information on abnormality of the image reading device; and when the image reading device reads a document, a processor configured to obtain the device abnormality information based on generated image data and the machine-learned model.

A memory control method uses a memory including a plurality of bank groups each having a plurality of banks. The memory control method includes masking write control data and read control data based on an inside-bank group constraint period that is a command to command interval during which a processing is restricted inside an identical bank group and an inter-bank group constraint period that is a command to command interval during which a processing is restricted inside different bank groups, and storing an unmasked command in an arbitration queue. An arbitration raises a priority order of control data requesting a processing on the bank group that has been accessed last among the plurality of bank groups.

A control system includes: image forming apparatuses at least one of which is installed in each of a plurality of areas in a building; a management apparatus; and alarms that are each provided for each of the areas, respectively. The management apparatus manages security of the building including the plurality of areas, detects an abnormal high temperature occurrence area by identifying the area in which the image forming apparatus from which the abnormal high temperature is detected is installed when the abnormal high temperature is detected in the image forming apparatus, and transmits a report command notification for reporting that the abnormal high temperature has occurred in the area in which an alarm is provided to the alarm which is provided in the abnormal high temperature occurrence area.

The controller of the image reading apparatus acquires second reference data indicating a reading value of a background plate by causing the reading unit to read the background plate during a non-document-reading period between a document-reading period and a document-reading period, calculates a first difference indicating a difference between a value in a first pixel range corresponding to an element group, among the plurality of photoelectric conversion elements, in a range under temperature influence by a given heat generation source and a value in a second pixel range, that is, part of a pixel range which does not fall under the first pixel range with respect to the second reference data, and updates, when the first difference exceeds a first allowable value, the first reference data by correcting a value in the first pixel range of the first reference data based on the first difference.
