Verfahren zum Ausrichten von Bogen unter Einsatz eines einzigen Sensors

Two separately programmed pinch rollers (114,116) provided in the paper path conveys a copy sheet (11). A sensor (132) detects the sheet position and output a corresponding signal to a controller. Based on the received signals, the controller generates motor control drive signals for the rollers so...

Zusammenfassung:	Two separately programmed pinch rollers (114,116) provided in the paper path conveys a copy sheet (11). A sensor (132) detects the sheet position and output a corresponding signal to a controller. Based on the received signals, the controller generates motor control drive signals for the rollers so as to deskew and register the sheet at registration position. Another sensor (134) is provided in downstream side of paper path at registration position to provide feedback for updating the control signals as pinch rollers wear. The controller deskews and registers the sheet at registration position. An independent claim is included for deskewing and registering method of print sheet.
