A document sheet length detection portion detects document sheets placed on a tray while distinguishing between a first size document sheet whose length in a conveyance direction is equal to or longer than a reference length, and a second size document sheet whose length in the conveyance direction is shorter than the reference length. A selection portion selects, as a specified conveyance process, one of a first conveyance process and a second conveyance process. A control portion, after a predetermined start event occurs, causes a conveyance device to execute the second conveyance process when the second conveyance process has been selected as the specified conveyance process and the document sheet length detection portion has detected the first size document sheet, and causes the conveyance device to execute the first conveyance process when a number of document sheets conveyed during the second conveyance process has reached an upper-limit number.

Various embodiments disclose a method for operating a printer apparatus that includes a print head. The method includes causing a media hub to retract a media in a retract direction along a media path. Further, the method includes causing a first media sensor to generate a first signal during retraction of the media. Furthermore, the method includes monitoring the first signal to detect at least one of a leading edge or a trailing edge of a label of the plurality of labels. Upon detecting the at least one of the leading edge or the trailing edge of the label, causing the media hub to retract the media by at least a predetermined distance, wherein the predetermined distance is a distance between the print head and the first media sensor.

A printing apparatus capable of conveying sheets to a sheet processing apparatus and to control the type of a sheet to be used as a cover sheet in a case where a book bound product is generated by switching back sheets each having an image printed, inverting the sheets and folding the inverted sheets, and to notify an error to a user based on the type of a sheet to be used as the cover sheet in a case where printing an image on the cover sheet is designated.

A drive motor drives conveyance rollers. A controller generates a control signal to control the drive motor based on information indicating a rotational speed of the drive motor. The controller generates an initial control signal to drive the conveyance rollers since before conveyance of a sheet by the conveyance rollers and acquires a characteristic value of the initial control signal as a reference value. While the conveyance rollers are conveying the sheet, the controller performs determination processing to determine whether or not to stop the drive motor driving the conveyance rollers based on the characteristic value of the control signal and the reference value.

An image reading apparatus includes a conveying unit configured to convey a document, a reading unit configured to read an image on the conveyed document, a measurement unit configured to measure a distance from an upper portion of a sheet feeding port for the document to an upper surface of the document, and a control unit configured to, according to the distance measured by the measurement unit, suspend the conveyance of the document by the conveying unit. According to a user operation for reading again the document of which the reading is suspended by the control unit, the conveying unit conveys the document and the reading unit reads the image on the document, and while the document of which the conveyance is suspended is conveyed again, the control unit does not suspend the conveyance of the document based on the distance measured by the measurement unit.

A printing apparatus includes a display that displays one of a first list including information of part of a plurality of sheet holding units, and a second list, including information of another sheet holding unit, of the plurality of sheet holding units, which is not displayed in the first list, and a user interface that receives a change instruction for changing the first list to the second list. The printing apparatus also includes a controller that controls the display based on the received change instruction received, such that, when an empty state occurs in a sheet holding unit of the part of the plurality of sheet holding units included in the information of the first list, the display initially displays the first list, and, when an empty state occurs in the other sheet holding unit included in the information of the second list, the display initially displays the second list.

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.

An image forming apparatus includes a storage unit storing sheets each including a wireless tag, a printer, a communication device, and a controller for controlling the printer to convey a first sheet, acquiring first strengths of signals from a first tag on a first sheet during the conveyance of the first sheet and second strengths from tags not sheets being conveyed. Based on the acquired strengths, the controller determines a threshold value for distinguishing between sheets being conveyed and not being conveyed. The controller then controls the communication device to write information to a tag on a sheet being conveyed based on the threshold value.
