Copy and scan printing may include scanning, by scanner disposed along a paper path between a paper delivery roller and a paper pickup roller, content of documents (302). Further, copy and scan printing may include determining whether the documents are to be copied (304), in response to a determination that the documents are to be copied, determining whether a page count of the documents to be copied is available (306), and generating copies of the documents (310).

A sheet conveying device includes a sheet placement table, a sheet discharge table, a conveyance mechanism, raising/lowering mechanism, and a raising/lowering control portion. The sheet discharge table is located below the sheet placement table. The conveyance mechanism conveys a sheet placed on the sheet placement table onto the sheet discharge table via an execution position at which image processing is executed by an image processing portion. The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to lower the sheet placement table when a human detection sensor configured to detect a human in a detection region has detected a human in the detection region.

The raising/lowering mechanism raises and lowers the sheet placement table. The raising/lowering control portion controls the raising/lowering mechanism to raise and lower the sheet placement table to a target position that is determined in accordance with a size of the sheet on the sheet discharge table.

An image reading apparatus includes: at least one processor configured to: set reading resolutions in a first and a second directions when reading an image of a document; determine an inclination amount of the document; correct an image to reduce the inclination amount; output image data indicative of an corrected image; and obtain information relating to a first direction length of the document. In a case where the first direction length of the document is less than a predetermined length and the processor outputs the image data indicative of the corrected image, whose resolution in the first direction is a first resolution and resolution in the second direction is a second resolution lower than the first resolution, the processor sets the reading resolution in the second direction to a third resolution higher than the second resolution.

A medium-transporting device includes: a medium-support section that has a first mounting surface inclined relative to a horizontal plane; a transport path for transporting a medium; a discharge stacker that is configured to switch between an extended state in which a second mounting surface that is inclined relative to the horizontal plane and that receives the medium discharged along the transport path is formed and a stored state in which the second mounting surface is stored in the medium-transporting device, a control section is configured to perform first control of switching the discharge stacker from the extended state to the stored state after the medium is discharged to the second mounting surface and second control of not switching the discharge stacker from the extended state to the stored state such that the medium remains mounted on the second mounting surface.

An image reading apparatus includes a stacking tray, a feeding roller, a restricting member configured to move to a restricting position and a retracted position, a reading sensor, a reversing roller configured to perform a reversing operation, a first conveyance path, a second conveyance, and a controller. The controller is configured to permit the reversing operation if the controller receives an execution instruction of a double-sided reading job on a sheet having a first size, and prohibit the reversing operation if the controller receives an execution instruction of the double-sided reading job on a sheet having a second size smaller than the first size.

An image reading apparatus includes an image sensor, a document feeder, and a processor. The document feeder includes a first driving device, a second driving device, a third driving device, a first sensor, and a second sensor. The first driving device includes a pick-up member to move documents from a tray to a document conveying path using a driving force through a first clutch. The second driving device is to move the tray with the documents to a side of the pick-up member using a driving force through a second clutch. The third driving device to move the documents along the document conveying path onto the image sensor using the driving force of the motor. The first and second sensors detect the documents on the document conveying path. The processor controls an operation of the first clutch based on the signals of the first and second sensors.

Copy and scan printing may include scanning, by scanner disposed along a paper path between a paper delivery roller and a paper pickup roller, content of documents (302). Further, copy and scan printing may include determining whether the documents are to be copied (304), in response to a determination that the documents are to be copied, determining whether a page count of the documents to be copied is available (306), and generating copies of the documents (310).

A sheet feeding apparatus includes a control unit. After finishing feeding the sheet, if the sheet detection unit does not detect the sheet when the lift plate is positioned at the sheet feeding position, the control unit sets the waiting position to a lowest position. Further, if the sheet detection unit detects the sheet and if the remaining amount detection unit detects that the remaining amount of the sheets is a predetermined amount or less, the control unit sets the waiting position to a height position between the sheet feeding position and the lowest position. Further, if the sheet detection unit detects the sheet and if the remaining amount detection unit detects that the remaining amount of the sheets is more than the predetermined amount, the control unit sets the waiting position to the lowest position.
