Embodiment Construction

[0019] For a general understanding of the present embodiments, reference is made to the accompanying drawings. In the drawings, the same reference numerals are used to refer to the same elements throughout. As used herein, the word "printer" refers to any device that produces an image on a medium, including but not limited to inkjet printers, copiers, facsimile machines, multifunction machines, and the like.

[0020] The present invention relates to an image fixation device for use in a phase change inkjet printer having an image bearing surface that moves within an imaging device. The image fixing device is proximate to the moving surface and includes at least one motion generator spaced from the moving image bearing surface to define a void. As explained below, the motion generator may have at least one ultrasonic transducer configured to extend into the void and then rapidly retract to contact or impact the image bearing surface as the image on the surface moves past the t...

Abstract

A phase change ink imaging device includes a transfixing apparatus configured to apply ultrasonic action to ink pixels deposited onto an image bearing surface to facilitate transfer and / or fixing of the ink pixels to print media.

Description

technical field [0001] The present invention relates generally to phase change ink printers, and more particularly to transfix devices for phase change ink printers. Background technique [0002] Phase change ink imaging devices utilize phase change inks to form images on recording media. These instruments typically include inkjets configured to eject droplets of molten phase change ink using direct printing or offset printing processes. In a direct printing process, ink is deposited directly on the print medium. In the offset printing process, ink is first deposited onto an imaging drum, which is then fixed to the print medium by pinch rollers. In most prior known devices, a fixed roll is loaded against the surface of the imaging drum to form the nip. The pages of print media are fed through the nip synchronously with the ink being deposited onto the surface of the drum. The predetermined pressure generated by rolling contact between the print media and the imaging drum...
