An image forming apparatus, detection method, and image forming system are provided. The apparatus includes a communication interface, a detector, and a notification interface. The communication interface communicates with a wireless tag at a connection position where a sheet conveyance path is formed between the apparatus and a retrofit device equipped with the wireless tag. 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.

A recording material transporting device includes a first transport unit that transports a recording material as a target to be transported and a second transport unit that has a transport belt, the transport belt receiving the recording material from the first transport unit and performing transport of the recording material toward a reader that reads an image on the recording material, the transport belt having a transport surface having different friction coefficients in a transport direction that is a direction of the transport and in an intersection direction that is a direction intersecting the transport direction, the friction coefficient in the intersection direction being smaller than the friction coefficient in the transport direction.

A belt transfer type multi-function device includes a control device performing controlling such that an image to be printed on paper already caught between a transfer roller and the belt roller is printed, and if printing should not be performed on a next paper, movement of the next paper is stopped on a transfer path before the next paper is positioned between the transfer roller and the belt roller, the image already transferred on the transfer belt is deleted in a state in which the next paper is stopped on the transfer path, and the next paper in a stopped state is ejected as a blank paper through a ejection port along the transfer path, so that the image already transferred to the transfer belt, which is to be printed on the next paper along the movement direction of paper, is not printed on the next paper.

A medium feeder includes a feed roller that feeds a medium loaded on a medium loading section; a transport roller disposed downstream relative to the feed roller; a first driving source that drives at least the feed roller; a second driving source that drives at least the transport roller; and a housing that houses the feed roller, the transport roller, the first driving source, and the second driving source, wherein the housing includes a lower unit that constitutes a lower part of the housing, and an upper unit openable relative to the lower unit, and the first driving source and the second driving source are disposed on both sides relative to a center part of the lower unit in a width direction perpendicular to a medium transportation direction.

An image forming apparatus includes an image former configured to form a first image on a first recording medium; a feeder configured to feed the first recording medium to the image former; a reader configured to read the first image formed on the first recording medium; a process executor configured to execute a predetermined process based on a first read image that is obtained by the reader by reading the first image; and a corrector configured to correct the reader based on a second read image that is obtained by the reader by reading a second image formed on a second recording medium fed by the feeder, and a predetermined read reference image.

An image reading apparatus includes a first scanner provided in a housing, a conveyance unit, and a first calibration member. The conveyance unit is provided with a separation unit which separates the first calibration member upward from the first scanner. When the first calibration member is separated, the separation unit releases connection between the conveyance unit and the housing.

Disclosed is a belt transfer type multi-function device for printing an image transferred on a belt to paper moving between a transfer roller and a belt roller, including a control device performing controlling such that an image to be printed on paper already caught between the transfer roller and the belt roller is printed as it is, and if printing should not be performed on next paper along a movement direction of paper, movement of the next paper is stopped on a transfer path of paper before the next paper is positioned between the transfer roller and the belt roller, the image already transferred on the transfer belt is deleted in a state in which the next paper is maintained to be stopped on the transfer path of paper, and the next paper in a stopped state is ejected as a blank paper through a ejection port of printed paper along the transfer path of paper, so that the image already transferred to the transfer belt, which is to be printed on the next paper along the movement direction of paper, is not printed on the next paper.

A scanner includes the following features. A first driven roller sandwiches a document together with a first drive roller and is capable of rotating in a driven manner. A second driven roller sandwiches a document together with a second drive roller and is capable of rotating in a driven manner. A driving unit rotationally drives the first drive roller and the second drive roller. A transmission unit transmits a rotational force from one of the first driven roller and the second driven roller to another of the first driven roller and the second driven roller.

Systems and methods are provided for document handling. Non-vision detection systems may be capable of detecting the dimensions, orientation, and/or position of a single sheet, or multiple stacked sheets. A document scanning arrangement may be capable of double sided scanning for sheets with various characteristics. The systems and methods provided may accommodate high throughput and rapid digitization of various types of documents, at a high quality.

A feeding device comprises a suction feeding unit having a belt for feeding a sheet in a suction state and a belt driving unit, a sheet detection sensor, and a control unit. The control unit controls the belt drive unit so as to feed the sheet in a feeding direction at a first speed. If the sheet does not arrive at the sheet detection sensor, the control unit controls the belt drive unit so as to execute a low-speed feeding of moving the belt in the feeding direction at a second speed lower than the first speed or so as to execute a reverse feeding of moving the belt in a reverse feeding direction opposite to the feeding direction.
