  • Patent number: 11829084
    Abstract: An electrophotographic printing system for printing with a set of toners including a white toner. A plurality of printing modules are configured to print respective toner patterns, each including a toner image printed onto a receiver medium being transported on a transparent transport web and a corresponding registration mark positioned outside a border of the receiver medium. A first registration mark sensing system is positioned to detect the registration marks printed with a first subset of the toners that doesn't include the white toner. A second registration mark sensing system is positioned to detect the registration marks printed with a second subset of the toners that includes the white toner. The registration mark sensing systems each include a reflector plate positioned behind the transport web. The reflector plate for the first registration mark sensing system is white, and the reflector plate for the second registration mark sensing system is black.

  • Patent number: 11138482
    Abstract: A digital printing system having a linear printhead includes corrections for in-track position errors. A data processing system implements a method for determining an in-track position function which includes printing a test target including a plurality of alignment marks, automatically analyzing a captured image of the printed test target to determine a measured in-track position for each of the alignment marks, comparing the measured in-track positions for the alignment marks to reference in-track positions to determine measured in-track position errors, and determining an in-track position correction function responsive to the measured in-track position errors. The in-track position correction function specifies in-track position corrections to be applied as a function of cross-track position. A corrected digital image is determined by resampling an input digital image responsive to the in-track position correction function.

  • Patent number: 9772576
    Abstract: A focus adjustment mechanism for adjusting a focus position of a printhead includes a rotatable pin that is rotatable around a pin axis. The rotatable pin includes a cam section located having a surface whose radial distance from the pin axis varies around its perimeter, and a gripping feature. An adjustment plate includes a gripping feature and is adapted to fit over and engage with the gripping feature of the rotatable pin such that the adjustment plate rotates together with the rotatable pin. A fastener fastens the adjustment plate to a support structure when the adjustment plate is positioned in a desired orientation. The printhead includes a frame feature which is pulled firmly against the cam section of the rotatable pin such that as the rotatable pin is rotated the frame feature rides on the surface of the cam section thereby adjusting the focus position of the printhead.

  • Patent number: 9537285
    Abstract: Laser diode apparatus, comprising a carrier (1) having a carrier top (11), a laser diode chip (4) arranged on the carrier top (11) emitting, during operation, electromagnetic radiation through a radiating face (5), which radiating face (5) runs perpendicularly to the carrier top (11), and at least one optical element (6) to deflect at least some of the electromagnetic radiation radiated by the laser diode chip (4) perpendicularly to the carrier top (11). By the use of a plurality of laser diode chips having wavelengths that differ very slightly from one another, speckles can be reduced. By means of a retarder plate (8) between the laser diode chip and the optical element it is possible to influence the polarization. A polarization cube enables the deflected light beam bundles to fully cover one another as differently polarized light beam bundles.
