  • Reducing reflectance variances of photoconductive surfaces
    Patent number: 11740568
    Abstract: In an example of the disclosure, an imaging oil is applied upon a photoconductor surface. An element is brought into contact with the imaging oil at the photoconductor surface. The element has a first refractive index that is within a predefined tolerance of a second refractive index of the imaging oil. The photoconductor surface is exposed to light emitted by a writing component. The light passes through the element and the imaging oil.
    Type: Grant
    Filed: September 18, 2018
    Date of Patent: August 29, 2023
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Lavi Cohen, Sasha Zilbershtein, Michael Vinokur, Michael Plotkin
  • Determining cleaning fluid thickness
    Patent number: 11119437
    Abstract: In an example, a cleaning station comprises a wiper blade to scrape cleaning fluid across a surface of a component of a print apparatus. A suction pump is to remove a cleaning fluid from a surface of the component of the print apparatus. A sensor is to determine the thickness of cleaning fluid on a surface of the component of the print apparatus. A controller is to vary a suction pressure of the suction pump based on measurements of the sensor.
