  • Patent number: 11338575
    Abstract: A controller for an inkjet printing device is configured to predict a remaining time period until a failure of the nozzle on the basis of a time curve of offset measurement values with regard to the offset of the ink droplets ejected by said nozzle. A compensation measure may be introduced promptly, before the actual failure of the nozzle on the basis of the prediction in order to have the effect that the compensation measure takes effect at latest at the point in time of the failure of the nozzle, and thus an interruption of the print quality may be prevented.

  • Patent number: 11292252
    Abstract: In a method and a device for synchronizing a first printing device with a second component (e.g. second printing device), based on a property of a print image printed by the first printing device, which the property is detected by an optical sensor, a first print image is printed and at least one part of the first print image is detected using the optical sensor to generate a corresponding sensor signal. A virtual sensor signal is determined based on first print data and a known position of the optical sensor. The virtual sensor signal is compared with a curve of the sensor signal and a position signal is generated based on the result of the comparison. A second component is started depending on the position signal.

  • Publication number: 20220059972
    Abstract: An adapter plug and an electronics housing includes an adapter plug of this kind, and a valve comprising an electronics housing of this kind. The valve has at least one electric actuator. The adapter plug has at least one receptacle for an actuator-side electrical contact element and a receptacle for an electronics-side electrical contact element. The two receptacles are electrically connected to one another. A main body of the adapter plug is designed for insertion into a recess of a wall portion of the electronics housing, which wall portion faces the actuator. The main body can be fastened to an edge of the recess with tolerance or play so as to be able to compensate for positional deviations of the at least one actuator relative to the electronics housing.

  • Publication number: 20220057009
    Abstract: An electrically actuated valve with a hydraulic unit includes a valve housing and at least one electric actuator. Electronics are fastened to the hydraulic unit and at the same time are precisely positioned so that a seal between the electronics and the actuator does not shift or fold over on itself. To this end, a positioning device is formed between the electronics and the hydraulic unit.

  • Patent number: 11207882
    Abstract: In an inkjet printing system, an actuator that is associated with a nozzle of a printing element is controlled in a normal operating mode, given a non-defective nozzle, to implement at least one standard refresh measure if the time period in which the actuator is not activated to output an ink droplet exceeds a preset limit value. After detection of a defective nozzle, the actuator is controlled in an error operating mode to implement at least one intensified refresh measure.

  • Publication number: 20210178754
    Abstract: In a method and a device for determining faulty print nozzles of a printing device, a plurality of print nozzles of at least one primary color are activated so that they print dots of a test image onto a recording medium, said dots forming lines as viewed in the printing direction, in a plurality of line rows that are successive as viewed in the printing direction and travel in the line direction. The lines of successive line rows are displaced counter to one another in the line direction, and the lines of each line row have a predetermined constant pitch from one another in the line direction. Furthermore, using an image detector, the printed test image is detected per pixel and image data are provided, wherein an image pattern processing implements a homogenization of the image data via filtering, evaluates the homogenized image data, and determines defective image regions.

  • Patent number: 10922593
    Abstract: A test image having a plurality of line rows is printed. The individual lines of the line rows are printed by different nozzles of a print head. The lines are thereby associated with the different line rows such that the lines of two directly adjacent line rows are not printed by all respective nozzles from two nozzle rows of the print head that are connected with one another via a common ink supply channel. Crosstalk between the nozzle rows, and print image artifacts of the test image that are linked therewith, may thus be advantageously avoided.

  • Publication number: 20180126758
    Abstract: In a method for an inkjet printing system, substantially parallel lines are printed in the transport direction with nozzles at different longitudinal positions along the transport direction of the recording medium. Based on the variations of the transversal distance of corresponding image points of the substantially parallel lines, the transversal movement of the recording medium may be detected and a dimension of the transversal movement may be determined.
