To provide a print control device, print control method, and storage medium with which, in a form where information related to the size of a sheet which is set in a printing apparatus is obtained and the size corresponding to the obtained information is displayed, the size corresponding to the obtained information is displayed more appropriately, in a case where the size corresponding to the information obtained by an obtaining unit matches any of multiple custom sizes corresponding to information stored by a storage unit before the information is obtained by the obtaining unit, all of the multiple custom sizes corresponding to the information stored by the storage unit before the information is obtained by the obtaining unit are displayed.

An image processing apparatus that prevents erroneous use of paper by enabling registration of user identification of a user who can use a paper feed deck in information about each paper feed deck of the image processing apparatus and controlling paper feeding so that just the user associated with the user identification can use a paper feed deck to which the user identification was added.

A sheet stacker includes a sheet stacking portion, a pair of sheet restrictors, a sheet feeder, and a position detector. A bundle of sheets is stacked on the sheet stacking portion in a stacking direction, and the sheet stacking portion moves in the stacking direction. The pair of sheet restrictors move in a width direction to regulate a position of the bundle of sheets in the width direction. The sheet feeder feeds a top sheet of the bundle of sheets at a sheet feeding position in a sheet feeding direction. The sheet feeding position is disposed at a top of the bundle of sheets in the stacking direction. The position detector is disposed between the pair of sheet restrictors in the width direction and above the sheet feeding position in the stacking direction. The position detector detects a position of the pair of sheet restrictors in the width direction.

In an image forming system, a hardware processor controls whether the first sheet is conveyed to an upstream side of the image former via a first conveying path which reverses sides of the first sheet or via a second conveying path which does not reverse the sides of the first sheet as well as the first conveying path, when images are formed on both sides of a plurality of the first sheets by the image former, in order to narrow a space between a plurality of the first sheets.

To provide a print control device, print control method, and storage medium with which, in a form where information related to the size of a sheet which is set in a printing apparatus is obtained and the size corresponding to the obtained information is displayed, the size corresponding to the obtained information is displayed more appropriately, in a case where the size corresponding to the information obtained by an obtaining unit matches any of multiple custom sizes corresponding to information stored by a storage unit before the information is obtained by the obtaining unit, all of the multiple custom sizes corresponding to the information stored by the storage unit before the information is obtained by the obtaining unit are displayed.

The control apparatus includes an acquisition unit, an air volume setting unit, and an air blow control unit. The air volume setting unit sets a volume of air to be blown toward the plurality of sheets from a separation blower based on the information on the processing job acquired by the acquisition unit or by manipulation of a user. When the air volume is changed from a first air volume to a second air volume different from the first air volume by the user, the air volume setting unit maintains the air volume as the second air volume, irrespective of the information on the processing job acquired by the acquisition unit, until the air volume is changed from the second air volume to an air volume different from the second air volume by the user.

A sheet property measurement device includes: a passage configured to allow a sheet to be manually inserted thereinto; a reading sensor configured to read a surface of the sheet inserted into the passage; a detection unit having a displacement member configured to be brought into contact with the sheet on downstream of a reading position of the reading sensor in an insertion direction in which the sheet is inserted and change in displacement amount depending on a thickness of the sheet, the detection unit being configured to detect the displacement amount of the displacement member; a sheet sensor configured to detect the sheet that has arrived at a detection position on downstream of the displacement member in the insertion direction; and a controller.
