    摘要: An inkjet offset printer includes at least one printhead to eject ink on a release agent applied to an image receiving member for subsequent transfer of the ink to the surface of a recording media. The release agent is applied to the image receiving member by at least two release agent applicators. The release agent can be selectively applied to process sheets of recording media of different sizes to improve print quality. Selective application of release agent to the image receiving member prevents release agent from migrating to a transfix roll, and subsequently to the back side of the media which affects the image quality.

    摘要: A calibration procedure for the synchronization of photoreceptor belt seams of tandem marking devices at system cycle-up. The procedure allows for images projected upon equivalent image panels relative to the belt seams of the tandem engines to be printed on the same sheet. The successive image panels on each belt are of relatively equal distance from the respective belt seams. Thus there is less frequency of the need to skip pitches in the printing operation to avoid either imaging on a belt seam or having the sheet arrive outside the input timing window for second engine sheet registration.

    摘要: A dynamic positional shifting, in the process direction, of the images on the second print engine of a tandem machine printing system in order to increase the time (and number of prints) between skipped pitches. Although the photoreceptor belts of each print engine may be out-of-phase, the relative positions of their individual seam zones may be derived during cycle-up. A control procedure then optimizes the position and spacing of each image within each belt revolution of the second engine, while still maintaining the minimum inter-document zone (IDZ) length required for paper path feeding and registration, xerographic process controls, and finishing. Removing the constraints of fixed-dimension IDZ's, as well as being able to adjust spacing and length of individual images on the belt, allows for optimization of system productivity by either delaying or eliminating the need for a skipped pitch.
