  • Charge roller positioning
    Patent number: 10379456
    Abstract: In one example, a method for calibrating a position of a charge roller is described. The method may include a processor positioning a first end of a charge roller to a first plurality of index positions, determining a capacitance between the charge roller and a photoconductor imaging plate at each of the first plurality of index positions, determining a first index position of the first plurality of index positions with a greatest change in capacitance, and calibrating a position of the charge roller based upon the first index position.
    Type: Grant
    Filed: October 29, 2018
    Date of Patent: August 13, 2019
    Assignee: HP Indigo B.V.
    Inventors: Shmuel Borenstain, Ami Halfon, Henryk Birecki, Seongsik Chang
