摘要:
Examples described herein include a print media edge repair system (100) that includes a first repair element (105) disposed adjacent to a media handling path to repair a leading edge (111) of a sheet of print media (110) as the sheet of print media moves into a position relative to a printing system associated with the print media edge repair system. The print media repairs may also include a second edge repair element (105) disposed opposite the first repair element across the media handling path to repair a trailing edge (112) of the sheet of print media as the sheet of print media moves into the position relative to a printing system (800).

A method of scanning documents obtains the document that is to be scanned from an input tray, transports the document at a transport velocity past a scanner to obtain image data therefrom, and stacks each scanned document aligned with trailing-edge registration in a sloped output tray, in the order of scanning, by a sequence that detects the trailing edge of the scanned document, feeds the leading edge of the scanned document from an exit nip in a forward direction and above the sloped output tray at a transport velocity, then changes the speed at the exit nip to an exit velocity, different from the transport velocity, according to the timing of the trailing edge detection. The trailing edge of the scanned document is ejected at the exit velocity. The exit nip speed is restored to the transport velocity for feeding the leading edge of a subsequent document.

Examples of stalling of operation of imaging devices are described herein. In an example, the imaging device includes an input roller assembly to transport a medium in the imaging device and a line feed roller assembly disengagably coupled to the input roller assembly to selectively drive the input roller assembly. To stall the operation of the imaging device, a line feed shaft of the line feed roller assembly can be automatically disengaged from the input roller assembly to discontinue advance of the medium along a print path.

Die Erfindung betrifft einen Falzapparat (10) einer Druckmaschine, insbesondere einer Rollenrotationsdruckmaschine, mit einer ersten Längsfalzeinheit (12) oder einem Magazinaufbau, mit einer in Transportrichtung eines Bedruckstoffs gesehen stromabwärts der ersten Längsfalzeinheit (12) oder des Magazinaufbaus angeordneten Schneideinheit (13), um vom Bedruckstoff durch Querschneiden Exemplare abzutrennen, und gegebenenfalls mit einer in Transportrichtung des Bedruckstoffs gesehen stromabwärts der Schneideinheit (13) angeordneten Querfalzeinheit und/oder zweiten Längsfalzeinheit (17). Erfindungsgemäß ist in Transportrichtung des Bedruckstoffs gesehen stromabwärts der Schneideinheit (13) entlang der Transportstrecke der Exemplare durch den Falzapparat mindestens ein Sensor (22) positioniert, der die Exemplare messtechnisch erfasst und ein Messsignal an eine Steuerungseinheit übermittelt, wobei die Steuerungseinheit auf Grundlage des von dem oder jedem Sensor (22) bereitgestellten Messsignals die Lage der Exemplare im Falzapparat relativ zu einem Maschinenwinkel bestimmt, und wobei die Steuerungseinheit abhängig von der so ermittelten Lage der Exemplare und von frei konfigurierbaren Grenzwerten für die Lage der Exemplare einen Stopper und/oder eine Warnmeldung auslöst bzw. generiert.
摘要:
An image forming apparatus includes a feeder unit, a separating unit, a conveying unit disposed downstream of the separating unit in a sheet feeding direction, an image forming unit disposed downstream of the conveying unit in the sheet feeding direction, a drive unit, and a control unit. The feeder unit feeds a sheet. The separating unit separates sheets fed by the feeder unit one by one. The conveying unit conveys the sheet. The image forming unit forms, while the sheet is being conveyed, an image on the sheet. The drive unit drives the conveying unit. The control unit controls the drive unit. After the conveyed sheet reaches the image forming unit, the control unit reduces a conveyance speed of the sheet conveyed by the conveying unit.

A printing apparatus comprises a feeding roller (3, 4) configured to feed a printing sheet stacked on a stacking unit, a conveyance roller (5,6) configured to convey the printing sheet fed by the feeding roller, printing means (7) configured to print the printing sheet conveyed by the conveyance roller, conveyance control means configured to control conveyance of printing sheets so that a trailing edge of a preceding sheet (1-A) as a printing sheet precedingly fed from the stacking unit and a leading edge of a succeeding sheet (1-B) as a printing sheet succeedingly fed from the stacking unit overlap each other; and determination means configured to determine whether to convey the succeeding sheet to a position facing the printing means while keeping an overlap state between the preceding sheet and the succeeding sheet.
