The detector detects a connection state between the retrofit device and the apparatus based on a communication result of the communication interface. The notification interface provides a notification based on the connection state detected by the detector. The detection method includes detecting a connection state between the retrofit device and the apparatus based on a communication result of the communication interface, and providing a notification based on the connection state detected in the detection. The image forming system includes an apparatus and a retrofit device provided with a wireless tag.

The present disclosure discloses methods and systems for managing multiple scan requests received at a multi-function device. The method includes receiving a scan request from a remote computing device of a remote user. Before executing the scan request, two conditions are checked. It is checked if document is present on a scanning platform of the multi-function device and further it is checked if one or more activities on a user interface of the multi-function device, are being performed. Based on the presence of the document on the scanning platform and the one or more activities on the user interface, the scan request received from the remote user is disallowed. This way, multiple scanned requests are managed at the multi-function device.

A document determination system includes a server apparatus that stores document data, a second multi-function printer that generates an authentic printed product, which is an authentic printed product in which a document represented by document data stored in the server apparatus is printed and in which at least a portion of the document is printed in composite black that is black represented using ink of a plurality of colors, and a third multi-function printer that reads a printed surface of a reading target including the authentic printed product and a duplicate of the authentic printed product. The server apparatus determines, based on whether at least the portion of the document represented by read data generated through reading by the third multi-function printer is printed in composite black, whether the reading target read by the third multi-function printer is the authentic printed product.

According to one embodiment, an image forming apparatus includes a conveyance system, a capacitance sensor, a processor, an image forming mechanism, and a tag writer. The conveyance system conveys paper. The capacitance sensor detects a value indicating the capacitance at a plurality of detection positions for the paper conveyed by the conveyance system. The processor detects that the paper conveyed by the conveyance system is provided with an RFID tag, and that the paper is being conveyed without overlapping with other paper based on the value indicating the capacitance detected at a plurality of detection positions by the capacitance sensor. If the processor detects that the paper is provided with an RFID tag and is conveyed without overlapping with other paper, the image forming mechanism forms an image on the paper. The tag writer writes data to the RFID tag provided on the paper on which the image forming mechanism forms the image.

An image reading apparatus includes a feed roller configured to feed a document, a transport roller disposed downstream of the feed roller and configured to transport the document downstream; a transport motor being a drive source of the transport roller; a reading unit disposed downstream of the transport roller and configured to read the document; and a control unit configured to control the reading unit and the transport motor, wherein the control unit is configured to obtain information on a document type and an inclination detection reference value for an inclination of image data set in accordance with the document type and obtained from the reading unit, and when the inclination of the image data exceeds the inclination detection reference value in accordance with the document type, the control unit stops the transport motor.

A conveyance apparatus includes a separation unit configured to separate and convey a sheet, a detection unit configured to detect a floating of the sheet passing through the separation unit, and a control unit configured to stop separate conveyance by the separation unit if the detection unit detects the sheet for not less than a predetermined time and/or a predetermined count.

A conveyance apparatus includes a separation unit configured to separate and convey a sheet, a detection unit configured to detect a height-direction deformation of the sheet passing through the separation unit on a downstream side than a sheet-conveying position of the separation unit in a conveyance direction of the sheet, and a control unit configured to stop the sheet conveyed by the separation unit if the detection unit detects the deformation of the sheet.

An image reading apparatus includes a feed roller configured to feed a document, a transport roller disposed downstream of the feed roller and configured to transport the document downstream; a transport motor being a drive source of the transport roller; a reading unit disposed downstream of the transport roller and configured to read the document; and a control unit configured to control the reading unit and the transport motor, wherein the control unit is configured to obtain information on a document type and an inclination detection reference value for an inclination of image data set in accordance with the document type and obtained from the reading unit, and when the inclination of the image data exceeds the inclination detection reference value in accordance with the document type, the control unit stops the transport motor.

According to an automatic document feeder of a multifunction peripheral according to the present invention, two tilt sensors are provided in the middle of a document conveyance path to detect a tilt degree of a document being conveyed along the document conveyance path. Here, for example, if the positional deviation representing the tilt degree of the document is greater than a predetermined threshold value ΔLs, the conveyance of the document is stopped. On the other hand, if this is not the case, the conveyance of the document is continued. In addition, the threshold value is set in accordance with the width dimension of the document, and in particular, the larger the width dimension, the smaller the threshold value.

An image processing apparatus is provided for scanning a medium including a scan region where target information is provided. The image processing apparatus implements processes of running an application for generating an electronic document; controlling the application to instruct a scanning device to scan the medium at a specified scan size, which is smaller than the size of the medium and includes at least the scan region, upon accepting a scan instruction from a user; controlling the scanning device to scan the medium and capture image data of the medium at the specified scan size based on the instruction from the application; executing a character recognition process on the image data captured by the scanning device to acquire the target information; and controlling the application to generate the electronic document including the target information acquired by the character recognition process input to a corresponding input field.
