A print instructing device includes: a recording section that, in a case in which history information does not include size information indicating a size of a print medium designated by a print demand that demands an execution of printing, records paper quality information indicating a paper quality of the print medium designated by the print demand in association with the size information in the history information; and a display controlling section that, in a case in which the size information is included in the history information and the paper quality information does not match the history information corresponding to the size information, causes confirmation information confirming whether or not to change the designated paper quality to be displayed.

An image forming apparatus (1) includes an image forming section (6), a plurality of recording paper trays (7a to 7n), storage (5), and a paper feed stage selecting section (12). The image forming section (6) performs advanced printing based on a paper profile. The paper feed stage selecting section (12) selects a recording paper tray (7) from the recording paper trays (7a to 7n) from which recording paper is to be fed to the image forming section (6) based on a printing instruction. When a specific paper profile is not associated with the selected recording paper tray (7), the paper feed stage selecting section (12) notifies the image forming section (6) of a manual setting and causes the image forming section (6) to perform simple printing.

An image forming apparatus includes an image forming unit, an intermediate transfer member, a transfer member, a power source, a fixing unit, a photosensor, and a control unit configured to perform a mode to output a test chart which is formed by transferring a plurality of test toner images from the intermediate transfer member onto a plurality of sheets of the recording material, the test chart being used to adjust the transfer voltage applied to the transfer member. The control unit is configured to adjust the transfer voltage based on a detection result of the photosensor detecting the plurality of test toner images fixed on the recording material. In a case where a jam occurred during execution of the mode, the control unit is configured to resume the mode after the jam has been recovered.

A medium transportation device includes a supply roller configured to send a medium downstream, at least one stopper configured to be switched between a blocking state in which the at least one stopper blocks the transportation path and an open state in which the at least one stopper opens the transportation path, and a controller configured to perform skew correction control in which a leading edge of the medium is brought in contact with the at least one stopper in the blocking state to correct skew of the medium. The controller is configured to obtain information about a stiffness of the medium and, when a second medium having a lower stiffness than a first medium is transported, the controller switches the at least one stopper from the blocking state to the open state to end the skew correction control earlier than the skew correction control of the first medium.

The control unit is configured to adjust the transfer voltage based on a detection result of the photo sensor detecting the plurality of test toner images recovered on the recording material. In a case where a jam occurred during execution of the mode, the control unit is configured to resume the mode after the jam has been recovered.

An image processing apparatus which reads an image of a document and prints the read image on a sheet includes a detecting unit, an obtaining unit, and a controller. The detecting unit detects a size of the document. The obtaining unit obtains a size of the sheet. The controller performs control such that, in a case where the size of the sheet obtained by the obtaining unit is not a predetermined size, an image in a reading region based on the size of the document detected by the detecting unit is read, and in a case where the size of the sheet obtained by the obtaining unit is the predetermined size, an image in a reading region based on the size of the sheet is read.

Provided is an image reading apparatus in which a setting screen is displayed upon detecting that a document is placed on the document tray. In a case where a document is placed on an automatic document conveyance device, if a paper jam occurs while using the automatic document conveyance device, a screen of a paper jam is preferentially displayed even when a setting of automatically displaying a selection screen of a sheet thickness is set at the time. This prevents a specific screen desired to be continuously displayed from being hidden upon detecting that a document is placed on a document tray.

A multifunction peripheral (MFP), which successively conveys a plurality of documents stacked on a document tray and reads the document, determines whether there is a difference among sizes of the plurality of documents in response to at least one of the documents being read by a scanner, in a case where a preview operation of a read image is performed, notifies a user of a possibility that documents having different sizes are mixed and read based on a result of the determination, enables a function of performing reading corresponding to respective document size of mixed size documents in which documents having different sizes are mixed, and provides navigation for prompting re-reading of the document.
