摘要： An offset printing apparatus for transferring a phase change ink onto a print medium having a phase change ink component for applying a phase change ink in a phase change ink image; an imaging member for accepting the phase change ink image from the phase change ink component, and transferring the phase change ink image from the imaging member to the print medium, and a transfix pressure member positioned in association with the imaging member, wherein the print medium passes through a nip formed between the imaging member and the transfix pressure member, and wherein the imaging member exerts pressure on the transfix pressure member so as to transfer and fuse the phase change ink image from the imaging member to the print medium, and further wherein the transfix pressure member includes a substrate; an underlayer positioned thereon; an intermediate layer positioned on the underlayer; and an outer layer positioned on the intermediate layer and the outer layer has a modulus of from about 1 to about 50 MPa, a thickness of from about 0.1 to about 2 mm, and wherein the pressure exerted at the nip is from about 750 to about 4,000 psi.

摘要： A capability is provided to reduce misregistration effects, and/or color-to-color registration errors, in output multi-color images based on velocity and position deviations and/or disturbances in transfer subsystems in image forming devices. A capability is provided to automatically compensate for torque disturbances caused by a photoreceptor belt seam crossing a mechanical device in a photoreceptor belt-based transfer subsystem in an image forming device. A learning algorithm, based on a mathematical model of transfer subsystem mechanical operational dynamics by which a series of performance curves could be generated, is employed to facilitate prediction of a torque disturbance profile in a mechanical motor driven transfer subsystem in an image forming device in order to produce a response profile which automatically predictively attempts to nullify the effects of the mechanical torque disturbance.

摘要： A reflex printing device having multiple print heads mounted at different locations around the circumference of the drum at different “angles” and an encoder disk mounted on the drum to allow for detection of the drum position as a function of time. An image defect due to a misalignment in the print process direction of the output from the multiple print heads is corrected by detection of an encoder position error function subtracted from itself shifted by the angle between the print heads.

摘要： A system and method for delivering phase change ink to a plurality of printheads is provided. The system includes an ink source having a housing for holding solid phase change ink, an ink melter assembly having a heated ink contact portion for melting the solid phase change ink and a drip point. The system also includes a first conduit for transferring the melted ink to a first printhead, and a second conduit for transferring the melted ink to a second printhead. The method includes melting a solid phase change into the liquid phase, transferring the liquid phase change ink to the first printhead in a first conduit, transferring liquid phase change ink to the second printhead in a second conduit. The solid phase change ink can be stored in a single ink source.

摘要： A method of maintaining a rotational velocity of an imaging drum during engagement with a transfer roll in an image producing device including: forming a nip to transfer an image from the imaging drum to media when the imaging drum is in engagement with the transfer roll; maintaining a substantially constant imaging drum rotational velocity mode during engagement with the transfer roll; sensing a lead edge of portion of the media prior to entering the nip; augmenting torque assist to increase the torque of the transfer roll when the media is in the nip for a defined period; and resuming the substantially constant imaging drum rotational velocity mode while a second portion of the media is in the nip.
