An image reading device including a reading transmission function of transmitting read data, generated by reading an original document, to a storage destination for storing the read data, the storage destination being included in an external device, the image reading device including a control unit configured to execute a communication test for determining whether communication with the storage destination is successfully performed, wherein the control unit includes a manual test mode for starting the communication test in response to an execution instruction of the communication test from a user and an automatic test mode for starting the communication test when a starting condition for starting the communication test is satisfied.

A controller of a printing apparatus performs first image reading including conveying a necessary number of original documents for printing on one sheet, reading an image on the conveyed original documents and terminating conveyance of the original documents. Further the controller performs displaying of a preview image and second image reading including conveying an original documents subsequent to the original documents in response to receipt of a print instruction through the user interface, and reading an image on the conveyed original documents with the sensor assembly, and printing the read images read on the sheets.

An image processing apparatus capable of preventing recurrence of a jam at the time of document reading is provided. The image processing apparatus includes a feeder, a reader, a storage device, and a processor. The processor causes the image processing apparatus to function as: a reading unit configured to cause the reader to read a document by a reading method among a plurality of reading methods including a conveyance-based reading method using the feeder; a storage control unit configured to, in a case where reading of a document with the reader by the conveyance-based reading method has failed, store information on the document in the storage device; and a notification unit configured to, in a case where an instruction to read again the document by the conveyance-based reading method is issued, issue, in accordance with the information, a notification that prompts to change the reading method set for the document.

An image processing device includes: an estimated size setting section (ACS determination section 151) which sets a document size of a document sheet as an estimated size; a threshold deciding section (ACS determination section 151) which decides a first threshold according to the estimated size; and an ACS determination section (151) which determines that the document sheet is a color document sheet when a number of color pixels reaches the first threshold. When an actual size of the document sheet is smaller than the estimated size, the threshold deciding section decides a second threshold which is smaller than the first threshold, and the document sheet is determined to be a color document sheet when the number of color pixels is the second threshold or greater and is determined to be a black-and-white document sheet when the number of color pixels is smaller than the second threshold.

An image reading apparatus to read a sheet being conveyed includes a memory and a reading device to read one side of the sheet in units of a line area orthogonal to a conveyance direction of the sheet. A read image of a first region corresponding to a leading edge side of the sheet in the conveyance direction is stored into the memory. A read image of a second region subsequent to the first region is not stored. A read image of a third region subsequent to the second region and corresponding to a trailing edge side of the sheet in the conveyance direction is stored in the memory. Each read image is an image read by the reading device. Predetermined processing is performed based on the read image of the first region and the read image of the third region stored in the memory.

An image reading apparatus includes a main body including a posture switching unit configured to switch the main body between a plurality of holding postures, a mode switching unit configured to switch between a plurality of modes corresponding to respective types of the document, display unit configured to display a first screen indicating a first combination of the holding posture and the mode, where the first combination is permitted, and a second screen indicating a second combination of the holding posture and the mode, where the second combination is prohibited, and a controller. The controller displays the first screen on the display unit when a state is switched to a state of the first combination, and displays the second screen on the display unit after a Predetermined time elapses since a state was switched to a state of the second combination.

An information processing apparatus includes a processor configured to set a state of a fixing device in a case where a state of an image forming apparatus including the fixing device transitions to a power saving state to be different depending on a property of the imaging forming apparatus.

A conveying path for a document (D) includes a first conveying path (R1) that turns back midway, and a second conveying path (R2) that does not turn back midway. When the first conveying path (R1) is used, a first side is read and the document (D) is discharged with the first side facing downward. When the second conveying path (R2) is used, a second side is read and the document (D) is discharged with the second side facing downward. When the second conveying path (R2) is used, a warning message (MS1) is displayed.

An image reading apparatus includes: a conveyance unit configured to convey the original; an image reading unit configured to read an image of the original conveyed by the conveyance unit by using a reading sensor to generate image data which represents a reading result; at least one processor configured to: detect a streak image in an image represented by the image data based on the image data; determine a content area in the image represented by the image data, the content area being an area where content is printed, and perform correction processing for removing the streak image by correcting the image data; wherein the at least one processor is configured to be operable in a first reading mode in which the correction processing is performed to image data corresponding to the streak image in an area outside the content area.

An image forming system includes an image forming unit, a sensor, and a controller. The controller is configured to control the sensor based on measurement modes including a first measurement mode and a second measurement mode. A sampling number of an image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the first measurement mode is less than a sampling number of an image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the second measurement mode.
