摘要:
A method and apparatus align an adjuster with an edge of media supported by a tray. The adjuster is operably coupled to a gauge that moves in response to movement of the adjuster. A sensor senses the gauge to detect a dimension of the media while the media is supported by the tray.

A method enables changes in the operation of a web printing system in response to web dimensional changes being detected. The method includes identifying a cross-process dimensional change in a web moving through a printing system, comparing the identified cross-process dimensional change to a predetermined threshold, and changing operation of a component in the web printing system in response to the cross-process dimensional change exceeding the predetermined threshold.

摘要:
An optical control method for use in print finishing, comprising the following steps: First, guiding a planar printed product (12, 13) along a conveying path past at least one optical sensor (14). Secondly, detecting an electronic image by the optical sensor (14), wherein the electronic image comprises at least one region of the printed product (12, 13). Thirdly, transferring the electronic image into a corrected image on the basis of corrective information, which converts a recording perspective of the at least one optical sensor (14) into a target perspective. Fourth, comparing the corrected image to a reference value or a reference image, and generating at least one signal (27) on the basis of a result of the comparison.

An apparatus for detecting overlapping flat objects, wherein each object has flat sides and narrow sides, includes a doubles detector configured to derive at least one feature of an object, a first imaging unit configured to produce an electronic image of a first flat side of the object, and a second imaging unit configured to produce an electronic image of a second flat side of the object. A determination facility of the apparatus is coupled to the first imaging unit and the second imaging unit to receive the electronic images, and to derive at least one further feature of the object. Further, a decision facility of the apparatus is coupled to the doubles detector and the determination facility to receive the least one feature and the at least one further feature of the object, and to determine whether the object is a single object or a number of objects.

Prior to assembling postal items of which at least a number each comprise a main document (2) and at least one annex (4, 5, 6) of at least one type, one or more mini-image files (23, 24,2 5) are stored, each defining a representation (26, 27, 28) of a part of a type of annex (4, 5, 6). On each main document (2) for a postal item (1) including the at least one type of annex (4, 5, 6) for one or each of a number of the annexes, the representation of the respective annex (4, 5, 6) defined by the mini-image file (23, 24, 25) is printed.
摘要:
A device is provided for monitoring sheets from which cards with a monetary value and/or identity cards are punched, where the cards are arranged in rows on the sheets. The device is configured such that the number of cameras used is independent of the number of rows of cards. The device has a table on which at least two sheets can be laid. A camera can be moved along and across the table, and a conveyor device travels along the table above the camera.

The print medium identification method includes (a) a step of obtaining first physical property information about a print medium, (b) a step of obtaining second physical property information which is different from the first physical property information about the print medium, (c) a step of obtaining first discrimination information for discriminating a type of print medium by inputting the first physical property information to a first discriminator, (d) a step of obtaining second discrimination information for discriminating the type of print medium by inputting second physical property information to a second discriminator, and (e) a step of identifying the type of print medium by using the first discrimination information and the second discrimination information.
摘要:
A printing system includes a print station disposed at a sheet transport path, a feed section arranged to feed media sheets of different media types into the transport path so as to be fed sequentially to the print station, and a controller arranged to receive print instructions concerning images to be printed, to schedule a sequence of the media sheets, and to control the feed section and the print station such that each image is printed on a sheet of a media type that has been specified for that image in the print instructions. A sensor is arranged at the transport path for detecting a quality condition of the sheets being fed to the print station, and the controller is adapted to receive a quality signal from the sensor and, when the quality of a sheet is found to be insufficient, to skip that sheet and to reroute the corresponding image to another scheduled sheet that is compatible with the print instructions.
摘要:
An image forming apparatus including an image forming portion, a moving portion, a re-conveyance portion, a detection portion, and a control portion is provided. The image forming portion is configured to form an image on a sheet that is conveyed. The moving portion is configured to move the sheet in a width direction. The re-conveyance portion is configured to invert the sheet having the image formed on a first surface thereof convey the sheet to the image forming portion again. The control portion is configured to control, based on a detection result of the detection portion, the moving portion to move the sheet in the width direction such that the center of the image formed on the first surface in the width direction and a center of the image to be formed on the second surface in the width direction coincide.
