  • Patent number: 6789875
    Abstract: In an implementation of printing mechanism hinged printbar assembly, a hinged printbar assembly pivots about a hinge between a print position and a service position. Print modules coupled to the hinged printbar assembly each have one or more printheads and the printheads of the print modules collectively span a width of a print media when the hinged printbar assembly is in the print position. A wiper assembly services the printheads on the hinged printbar assembly and includes printhead caps to cover the printheads on the hinged printbar assembly.
    Type: Grant

  • Patent number: 6637858
    Abstract: A print unit, such as an inkjet printing mechanism, includes a hinged printbar assembly that has print modules with one or more printheads to deposit an imaging medium, such as ink, onto a print media. The one or more printheads of the print modules collectively span a width of a print media when the hinged printbar assembly is in a print position. The hinged printbar assembly pivots about a hinge from the print position to a service position to provide service access to the one or more printheads of the print modules. The print unit also includes a wiper assembly having one or more wipers that correspond to the one or more printheads, such that when the wiper assembly and the print module are positioned in the service position, the wipers clean the printheads.

  • Patent number: 6595619
    Abstract: A print unit, such as an inkjet printing mechanism, includes a printbar assembly that has print modules with one or more printheads that collectively span a print region corresponding to a width of a print media and deposit an imaging medium, such as ink, onto the print media. Wiper assemblies move from a print position to a service position in the print region to service the one or more printheads of the print modules. A wiper assembly has one or more wipers that correspond to the one or more printheads, such that when the wiper assembly and the print module are positioned in the service position, the wipers clean the printheads. The wiper assembly also has one or more printhead caps that cover the one or more printheads on the print modules.

  • Patent number: 6592200
    Abstract: A print unit, such as an inkjet printing mechanism, includes a printbar assembly that has print modules and integrated servicing assemblies to service printheads on the print modules. The one or more printheads of the print modules collectively span a width of a print media and deposit an imaging medium, such as ink, onto the print media. The integrated servicing assemblies move from a retracted position within the printbar assembly to a service position to clean and/or cap the one or more printheads of the print modules. A servicing assembly has one or more wipers that correspond to the one or more printheads, such that when the servicing assembly and the print module are positioned in the service position, the wipers clean the printheads. The servicing assembly also has one or more printhead caps that cover the one or more printheads on the print modules.

  • Patent number: 6428161
    Abstract: An embodiment of a drying apparatus for drying ink deposited onto media includes an electromagnetic energy source to generate electromagnetic energy. The embodiment of the drying apparatus also includes a rectangular waveguide coupled to the electromagnetic energy source. The rectangular waveguide includes slots in the axial direction of the rectangular waveguide on opposite sidewalls corresponding to the largest sides forming a cross section of the rectangular waveguide. The electromagnetic energy source is configured to establish a TE01 mode within the rectangular waveguide, resulting in an electric field substantially perpendicular to the longitudinal axes of fibers within the media and thereby reducing power dissipated within the media while providing sufficient power for drying the ink during a drying operation.
