An image scanning apparatus that is capable of executing control about an interrupt scan without using another apparatus. The image scanning apparatus includes a scanner and a controller. The scanner scans a document. The controller determines whether interrupt execution of a second scan that is different from a first scan is permitted based on a setting relevant to the first scan that is being executed. The scanner executes the second scan after suspending the first scan in a case where the interrupt execution of the second scan is permitted, and the scanner restarts the first scan after executing the second scan.

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.

The following steps are performed in connection with a photodiode circuit: a) resetting the photodiode circuit; b) determining when a photodiode voltage changes in response to illumination to reach a threshold; and c) updating a counter in response to the determination in step b). The steps a) to c) are repeated until an end of a measurement period is reached. The value of the counter at the end of the measurement period is then output to indicate an intensity of the illumination.

A configuration is provided in which in a case where a user operation is performed on an image forming apparatus or a data processing apparatus while the image forming apparatus and the data processing apparatus are operating in cooperation with each other, the automatic clearing timers of both the apparatuses are reset.

An image reading apparatus includes a main body that performs a scanning operation of sequentially reading a plurality of documents by a reading section that reads the plurality of documents and a document transport section that transports the plurality of documents to the reading section. The main body has a plurality of postures with different inclinations. The image reading apparatus includes a posture acquisition section that acquires posture information indicating the posture of the main body, and a controller that controls an operation of the document transport section. The controller interrupts the scanning operation when the posture indicated by the posture information is changed from a start of the scanning operation during the scanning operation.

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.

A reading apparatus includes a transport unit, a multi-feed detection unit, a reading unit, and a controller. When a multi-feed of the document is detected by the multi-feed detection unit, the controller multi-feeds causes the transport unit to discharge, downstream of the transport path, a multi-fed document for which the multi-feed is detected and then temporarily stops the transport, stores multi-fed page information indicating a page number of the multi-fed document, restarts the transport after the temporary stop, and after the reading unit reads a remaining document whose page succeeds a page of the multi-fed document, performs a re-reading process including the transporting and the reading of the multi-fed document, respectively, and inserts, based on the multi-fed page information, second read data acquired by the reading in the re-reading process into first read data acquired by the reading completed before the re-reading process.

Disclosed herein are a method and apparatus for performing print jobs in a printing system including a host device and a printing device. The method of performing print jobs in a printing system including a host device and a printing device includes: requesting printing while transmitting print data and identifications (IDs) corresponding to one or more print jobs, included in a job list, to the printing device; if an identification (ID) corresponding to at least one completed print job is received from the printing device, updating the job list by deleting a print job corresponding to the received ID from the job list; if an error has occurred in the printing system, determining whether the error has been resolved; and if it is determined that the error has been resolved, resuming printing.

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.

A printer includes: a motor driving a transport member according to an operational parameter, to transport media along a media path from a media supply to a printhead; a first distance sensor disposed on a first side of the media path to measure a first distance between the media and the first distance sensor; and a controller configured to: receive the measured distance; detect curling of the media based on the first measured distance; and responsive to detecting curling of the media, update the operational parameter at the motor.
