  • Transferring printing fluid to a substrate
    Patent number: 11520248
    Abstract: Some examples relate to printing apparatuses and methods. In an example, a roller transfers printing fluid to a substrate. In some examples an electrically grounded roller is positioned proximate the electrically charged roller and guides the substrate. In some examples, the roller is an electrically charged roller. In some examples an electric field is applied and its strength is varied based on a dielectric coefficient of the substrate and/or a thickness of the substrate.
    Type: Grant
    Filed: December 12, 2018
    Date of Patent: December 6, 2022
    Assignee: Hewlett-Packard Development Company, L.P.
    Inventors: Ehud Eyal, Eric Nelson, Nadav Shalem
  • Heating fluid print agent with ultraviolet radiation
    Patent number: 11407236
    Abstract: A method is disclosed. The method may comprise applying a coating of electrically charged fluid print agent to a developer surface, the fluid print agent comprising particles of thermoplastic resin in a carrier fluid. The method may further comprise controlling migration of fluid print agent from the developer surface to form an image from fluid print agent on a first surface. The method may further comprise irradiating the print agent on the first surface with ultraviolet radiation to heat the print agent to a temperature of at least 70° C. to melt the thermoplastic resin. A print system and a heating unit are also disclosed.
