  • LIQUID ELECTROPHOTOGRAPHY PRINTING ON FABRICS
    Publication number: 20230015928
    Abstract: A liquid electrophotographic (LEP) printing device that includes a photo-imaging plate (PIP) to receive a liquid printing fluid, the liquid printing fluid including a pigment incorporated into a resin, a charge conductor, and a carrier liquid, and a transfer roller to transfer the liquid printing fluid from the PIP to a fabric substrate while wet.
    Type: Application
    Filed: September 27, 2022
    Publication date: January 19, 2023
    Applicant: HP INDIGO B.V.
    Inventors: Harsh Pranav DESAI, Evgeny KOROL, Avinoam HALPERN

  • Developer unit drying
    Patent number: 10635026
    Abstract: In one example, a method for drying a developer unit of a liquid electrophotographic printer. After printing is complete, development voltage biases are applied to the developer unit while a liquid marking agent flows to the developer unit. The liquid marking agent flow to the developer unit is stopped. Drying voltage biases, lower than the development voltage biases, are applied to the developer unit. Idle voltage biases are applied to the developer unit when dry.
    Type: Grant
