Patent number: 11801675Abstract: A controller may detect an elevation of a recording medium that is to be printed to, the elevation may result in the printing element of a printing device being negatively affected. The controller may automatically produce a time-limited printing pause of the printing element in which the printing gap between the printing element and the recording medium is temporarily enlarged in order to direct the detected elevation past the printing element. A negative effect on the printing device given the presence of a damaged recording medium may thus be efficiently and reliably avoided or reduced.Type: GrantFiled: January 28, 2022Date of Patent: October 31, 2023Assignee: Canon Production Printing Holding B.V.Inventors: Bernd Hausmann, Hubert Drexler, Bernhard Holzner, Stephan Pilsl, Ulrich Bäumler, Lucian Petrut, Christian Wallis

Patent number: 9592662Abstract: In a method to damp an oscillation of a roller driven via a drive in a printing system, a printing substrate web is directed across the roller, the roller and the printing substrate web forming a system capable of vibrating. With the drive the roller is driven with a predetermined nominal moment. With a sensor, a real value is determined of a variable representative of a velocity with which the printing substrate web is transported by the roller. In aid of a predetermined calculation rule, a correction moment is calculated from the determined real value such that a damping of the vibration-capable system results like a mechanical viscous damper. The correction moment is added to the predetermined nominal moment upon activation of the drive.Type: GrantFiled: September 17, 2015Date of Patent: March 14, 2017Assignee: Océ Printing Systems GmbH & Co. KGInventors: Peter Thiemann, Stephan Pilsl, Martin Pappenberger

Patent number: 8926049Abstract: In a method to execute a pause in an ink printing system printing operation in which a printing substrate web is printed with print bars having print heads, with aid of a take-up roller moving the printing substrate web at printing speed past the print bars in a transfer printing zone in order to generate print images. Upon triggering the pause, a strain state of the printing substrate web is measured at a beginning of the pause and stored as a desired strain state. During the pause, the strain state of the printing substrate web is measured as a real strain state at selectable points in time, and the real strain state is compared with desired strain state. Given a deviation of the real strain state from the desired strain state, at the selectable points in time the take-up roller is controlled so that the strain state of the printing substrate web assumes the desired strain state at the beginning of the pause.Type: GrantFiled: July 23, 2013Date of Patent: January 6, 2015Assignee: Océ Printing Systems GmbHInventors: Mehrad Biglari, Admir Lela, Peter Thiemann, Stephan Pilsl

Patent number: 8794856Abstract: In a method or device to sample a web movement, an incremental encoder translates the web movement into two phase-offset output signals. A quadrature decoder generates first and second digital output signals with two respective signal levels. The first output signal is designated as a forward signal and the second output signal is designated as a backward signal. An evaluation circuit outputs a control signal and has a first counter that counts a signal change of the forward signal and subtracts from the count a signal change of the backward signal. A second counter counts a signal change of the control signal. A comparator compares values of the first and the second counters. A disabling device enables the forward signal if values of both the first and second counters are the same so that the forward signal is output, and disables the forward signal if values of the two counters are different.Type: GrantFiled: August 20, 2010Date of Patent: August 5, 2014Assignee: Océ Printing Systems GmbHInventors: Peter Thiemann, Stephan Pilsl

Patent number: 8325373Abstract: In a printing system or method, two printing units apply printing ink onto a recording material, each printing unit having multiple apparatuses with a respective microprocessor controller. The microprocessor controllers are connected with one another via a respective data bus segment and each data bus segment has multiple data lines. The two data bus segments of the two printing units are connected with a bus switch. The bus switch has a data switch to connect a respective one of the lines of the one data bus segment with the corresponding line of the other data bus segment, a respective terminating resistor being provided for each data bus segment. The terminating resistors are connected with a respective terminating switch coupled with the data switches such that either all terminating switches are open and all data switches are closed, or all terminating switches are closed and all data switches are open.Type: GrantFiled: January 24, 2012Date of Patent: December 4, 2012Assignee: Océ Printing Systems GmbHInventors: Stephan Pilsl, Martin Pappenberger, Arno Best

Patent number: 7835684Abstract: In a method for control of an electrophotographic printer or copier, information that refer to a single sheet are determined from print data supplied to the printer or copier. Dependent on said information, a transport path of the single sheet through the printer or copier to generate at least one print image on at least one side of the sheet is determined. A system time of the printer or copier is provided that is the same for at least first and second control units of the printer or copier. At least one desired point in time at or until which at least one sensor signal is expected or at least one actuator is activated is established dependent on the transport path, the desired point in time referring to the system time of the printer or copier.Type: GrantFiled: October 16, 2003Date of Patent: November 16, 2010Assignee: Oce Printing Systems GmbHInventors: Robert Heimbach, Rainer Katterloher, Stephan Pilsl, Stefan Zimprich, Christian Ferti, Werner Zollner, Christoph Nemmaier, Helmut Sippel, Hubert Drexler

Patent number: 6499733Abstract: The invention relates to a method of feeding a sheetlike material (50-54) into a printer. An externally located cover sheet (50-54) is removed from a pile of sheets and conveyed towards a section (a10-a12) of the transport path at a transport speed (V0, V1). The lower limit (v0) of the transport speed is the same as or greater than the transport speed (v0) of the sheets (50-54) in section (a1-a12). Conveyance of the sheet (52,54) is delayed until section (a10-a12) has been reached. Identical predetermined spacing (AS) thus occurs between immediately successive transported sheets (52,54).Type: GrantFiled: June 8, 1999Date of Patent: December 31, 2002Assignee: Oce Printing Systems GmbHInventors: Gerhard Oberhoffner, Stephan Pilsl

Patent number: 6179281Abstract: In order to control the ejection of sheets from input compartments in a paper output device belonging to a printing or photocopying system, verification occurs as to whether a previously processed sheet has been removed as soon as it has been established that at least one input compartment is almost empty. Ejection of the sheet immediately following according to the order of processing occurs thereafter. These steps are repeated until the input compartment is empty. The printing operation is then stopped.Type: GrantFiled: June 18, 1999Date of Patent: January 30, 2001Assignee: Oc{acute over (e)} Printing Systems GmbHInventors: Stephan Pilsl, Bernward Heller, Gerhard Oberhoffner
