An image forming apparatus includes an image forming unit configured to perform a printing process of forming an image on a print medium based on print data, and a processor. The processor is configured to determine whether or not the printing process has completed based on remaining print data to be printed, when the print medium is removed from a paper discharge tray in which the print medium on which the image is formed by the image forming unit is placed, and to cause a warning to be output upon determining that the printing process has not completed based on the remaining print data to be printed.

An image reading device includes an imaging device to capture an image of a document placed below the imaging device to generate a document image and output an image signal based on the document image, circuitry to determine a size of a fed-sheet based on information on the fed-sheet, the fed-sheet being a sheet to be formed with the document image, generate a frame image for the document image, the frame image having a size equal to the size of the fed-sheet, and synthesize the frame image with the image signal output from the imaging device to generate a synthesized image, and a display to display the synthesized image.

When a device management server requests obtainment of recorded video at the time of an error in an image forming apparatus, a device management client confirms that there is a request for obtainment of recorded video, and makes a request for desired recorded video to a camera management server. The device management server receives recorded video from the camera management server through the device management client.

Disclosed is a preprinting system of secured information connected to a game host device. The preprinting system includes a controller, a printer, a plurality of printer detectors, a housing, a plurality of housing detectors. The controller is configured to communicate with the game host device, and to receive a game information signal and a status checking request signal. The printer is electronically connected to the controller, which is configured to print a game draw of the game program on printable medium, and the printed printable medium is partially revealed to the player while the game result draw thereon is unknown to the player. By preprint game draw of the game program, the possibility of adulteration from the game system is eliminated, the preprinting system also provides reliability, and the verification mechanism provides information security of digital chance games to the players. An preprinting method of secured information is also disclosed.

A document processing device includes a scanner, a display, a notification unit, and a control unit. The scanner is configured to read a document provided on a document table. The display is configured to display image data of the document read by the scanner. The notification unit is configured to provide a notification warning to indicate that the document has not been removed from the document table. The control unit is configured to detect the document on the document table.

What is disclosed is a system and method for detecting a folded page in a digital image of a scanned document. In one embodiment, the present method involves receiving a digital image of a document which has been converted to a digitized form using a document scanning device. The digital image is segmented horizontally and vertically to obtain a plurality of image segments. An edge profile is generated for the horizontal and vertical segments. A determination is then made, based on a comparison of the profiles, whether a page fold exists in the digital image. If a page fold is determined to exist in the digital image, the user is notified and the digital image is not sent to a print engine. Otherwise, the digital image is printed.

A method for generating an alert to enable a user to retrieve a printed document from an image scanning device is described. Multiple portions of a digital image of a printed document obtained through the scan task, are identified. Thereafter, movement of a scan-head assembly of an image scanning device is controlled so as to position the scan-head assembly over a target area of the printed document. The scan-head assembly may be activated to capture a reference image and a series of verification images of the target area of the printed document. Thereafter, the reference image and each of the series of images are compared. Based on the comparison, an alert is generated, wherein the alert is to indicate that the printed document is to be retrieved from the scanning device.

An image reading apparatus includes: a first size-detecting portion which detects a size of an original disposed on a disposing portion; a conveying portion which conveys the original disposed on the disposing portion to a reading portion, a second size-detecting portion which detects the size of the original to be conveyed by the conveying portion; a controller which calculates an overlap region between a reading region and an original region, with the reading region determined based on a reading size obtained by a obtain portion and the detection of the first size-detecting portion, and the original region determined by the second size-detecting portion; and a notifying portion which makes a predetermined notification based on the information that has been calculated.

Systems and methods for detecting the presence of metallic objects in media to be conveyed in a medium transport system are disclosed. One or more induction sensors are included in the medium transport system to detect the presence of metal in the transported media, with detection signals sent from the sensors to a system processing unit. An ultrasonic detector is employed in some embodiments to output another detection signal. One or more microphones may also be included, for detecting the sound created as the medium is being transported. The system processing unit analyzes various detection signals and analyzes computed sound values from the microphones, to determine the presence and location of metal in the media. A position jam detector may assist in determining jams of the media along the medium transport path.
