  • Patent number: 8718528
    Abstract: Various embodiments provide materials, apparatus, and methods for forming an image. Exemplary imaging apparatus can include one or more light sources configured to treat toner images after they are transferred on an image receiving substrate (e.g., a copy sheet). The toner images can be formed of an opto-thermal toner containing opto-thermal elements in a toner composition. The fuser subsystem may or may not be configured in the disclosed imaging apparatus.

  • Patent number: 8646179
    Abstract: A method for producing an inkjet printhead that includes aligning and stacking together an aperture plate and a plurality of jetstack plates; bonding together the aperture plate and plurality of jetstack plates; after the bonding step, depositing a layer of coating material to a surface of the aperture plate by inkjet printing to form a coating on at least a portion of the surface of an outlet surface of the aperture plate; and curing the layer of coating material to form a cured coating. The method may also include forming a second cured coating.
