摘要： Microwave dryers and a method of fabricating microwave dryers are disclosed. The microwave dryers include a microwave source that generates electromagnetic energy to dry a wet colorant applied to a continuous-form print medium. The microwave dryers further include a microwave waveguide electromagnetically coupled to the microwave source that transports the electromagnetic energy between a first end and a second end. The microwave waveguide includes a passageway that is sized to pass the continuous-form print medium through the microwave waveguide. The microwave dryer further includes a plurality of microwave absorbing elements within the microwave waveguide that absorb the electromagnetic energy and heat the wet colorant.

摘要： Systems and methods are provided for chokes for microwave radiation. One embodiment is an apparatus that includes a choke assembly. The assembly includes a first choke plate, and a second choke plate. The assembly also includes a first layer disposed at a surface of the first choke plate. The first layer includes a material that attenuates microwave radiation via dielectric heating by converting the microwave radiation into heat, and a substance, disposed between the material of the first layer and the gap, that is transparent to the microwave radiation. The assembly further includes a second layer disposed at a surface of the second choke plate that faces the first layer. The second layer comprises the material that attenuates the microwave radiation via dielectric heating by converting the microwave radiation into heat, and the substance, disposed between the material of the second layer and the gap.

摘要： Embodiments described herein provide a microwave coupler that utilizes a microwave shield within an interior of the microwave coupler to mitigate Radio Frequency (RF) leakage from an end of the microwave coupler. The microwave coupler includes a ramp section that is configured to mate to a microwave source, with the ramp section extending from an opening in a top wall of an enclosure. One end of the enclosure is configured to mate to a microwave waveguide, while an opposing end may be open or partially open. The microwave shield is located between the opposing end of the enclosure and the opening in the top wall, and extends from the top wall of the enclosure towards a bottom wall of the enclosure.

摘要： Systems and methods are provided for cover plates for printheads. One embodiment is an apparatus that includes a cover plate for a printhead. The cover plate includes multiple layers of electrically conductive material, a layer of nonconductive ferrite that is sandwiched between the multiple layers, and at least one connector that penetrates through the multiple layers and the layer of nonconductive ferrite to form a conductive pathway for electric current between the multiple layers through the layer of nonconductive ferrite. The cover plate also includes at least one opening that penetrates through the multiple layers and the layer of nonconductive ferrite, and that is configured to align with nozzles of the printhead.

摘要： Microwave dryers that utilize multi-path and/or space saving configurations are disclosed. In a multi-path configuration, a print medium makes two or more passes through the passage(s) of microwave waveguide(s) in a microwave dryer, thereby increasing the exposure time of the print medium to electromagnetic energy within the waveguide(s). In a space saving configuration, the print medium takes a non-linear path through the microwave dryer, thereby reducing a footprint of the microwave dryer.

摘要： Serpentine microwave dryers and a method of fabricating same are disclosed. The serpentine microwave dryers utilize microwave waveguides that includes passages through a short axis of the microwave waveguides that are sized to pass a continuous-form print medium. A long axis of the microwave waveguides are positioned across a width of a media path of the continuous-from print medium. Electromagnetic energy transported along the microwave waveguides is used to dry wet colorants applied to the continuous-form print medium. At least one of the microwave waveguides has an offset from other microwave waveguides that is perpendicular to the media path of the continuous-form print medium. The offset reduces an attenuation of the electromagnetic energy in microwave waveguide(s) that are offset.
