An automatic document feeder includes a media path to route media through the automatic document feeder, at least one media tray to one of supply the media to the media path and receive the media from the media path, and an automated media tray extender at an end of the media tray, the automated media tray extender to be positioned based on a presence of the media in the media tray.

An image reading device installed in an image forming apparatus includes a document placing table having an image reader, and an auto document feeder (ADF) rotatably supported by the document placing table. The ADF is rotatable between a closed position where an upper surface of the document placing table is uncovered and an opened position where the upper surface is covered. The ADF includes a document tray, a document discharge tray arranged at a position below the document tray with a space, and a front wall fixed to a front side of the document tray. A cutout part is formed on the front wall with a front side of the space being opened through the cutout part. The ADF further includes a hand grip provided to an upper edge of the cutout part, and used to lift the ADF from the closed position toward the opened position.

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.

An information processing device including multiple operation units operable for a user, comprises: a storage; and a hardware processor that: detects the user; detects the operation unit operated by a first user from among the multiple operation units when the first user is being detected; stores operation information in which operation unit is recorded in the storage; and reads the operation information in the storage and notifies a second user of the operation unit operated by the first user when the second user is detected.

An automatic document feeder includes a document loading detector, a document feeder, a document guide, a guide width measurer, a document width acquirer, a guide shift determiner, a document skew detector, a skew determiner, a warning display information generator, and a display. When a detected skew of a document is determined to be unallowable, the document feeder stops a feeding of the document. The warning display information generator generates a warning content about a feed trouble that stopped the feeding of the document, and the generated warning content about the feed trouble is displayed on the display.

An image reading apparatus includes a transport section that can transport original documents along a transport path, a reading section configured to read images of the original documents transported by the transport section, an output controller configured to output data of the original documents read by the reading section, a multi-sheet feed detection sensor configured to detect a multi-sheet feed of the original documents transported by the transport section, and an instruction section configured to issue an instruction to disable multi-sheet feed detection by the multi-sheet feed detection section.

An information processing apparatus includes an imaging device to image a medium, a communication device provided so as to communicate with a plurality of information processing apparatuses, and a processor to acquire a use state of the image reading apparatus, set an information processing apparatus capable of executing imaging control of the imaging device, and control the imaging device according to an instruction signal from the set information processing apparatus. The processor determines whether to set a second information processing apparatus as the information processing apparatus capable of executing the imaging control, based on the use state, when receiving a request signal of the imaging control from the second information processing apparatus in a state where a first information processing apparatus is set as the information processing apparatus capable of executing the imaging control.

An electronic device and a document processing system both with cost saving function are disclosed. The electronic device performs a blank page counting process on a received first document file data containing blank pages, in order to generate cost information of non-blank pages and display it for reference. With the above electronic device, it is able to save the cost of outputting blank pages and avoid waste of paper to achieve the purpose of cost saving. The document processing system includes the above electronic device, which is connected to the document processing system via a network.

There is provided a mechanism for determining whether to perform processing of lifting up a document tray upon detection of a document depending on an active application. A method for controlling an image processing apparatus includes lifting up a document tray upon placement of a document on the document tray, conveying the document placed on the document tray lifted up in the lifting, reading the document conveyed in the conveying, and registering, for an application, whether to lift up the document tray upon the placement of the document on the document tray.

An image forming apparatus includes an image reading unit. When printing a postcard is selected, a preview screen including a preview image about an image on a communication side of the postcard read by the image reacting unit is displayed on a display. At this occasion, an instruction image indicating an orientation of an address side of the postcard is also displayed. When it is instructed to turn over the preview image on the communication side, the preview screen including the preview image on the address side is displayed on the display. When the orientation of the address side and the orientation of the communication side do not coincide with each other, or when they are not as intended by a user, printing is performed after the image on the communication side is rotated according to the user's operation.
