    Abstract: 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.

    Abstract: 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.

    Abstract: An electrophotographic marking device includes a xerographic marking module and an environmental control module which controls temperature and relative humidity inside the marking module. The environmental module has a main plenum chamber and a divided or split plenum chamber to create and supply two air streams with different temperatures and/or different humidities and/or different airflow volumes and/or airflow rates to a marking engine. A primary air stream plenum chamber is closed loop controlled by input from one or more temperature and/or humidity sensors in the xerographic module. A secondary air stream plenum chamber is open loop controlled by means of one or more temperature and/or humidity sensors in one or mode developer housings. Heating of the secondary air stream is achieved by heat generated in the developer housing(s) and/or one or more heaters distinct from the developer unit elements. The system achieves balanced, thermodynamically adjusted, air flows.

    Abstract: A method of calibrating a printing system for positioning at least one printed image, the printing system includes a first image bearing surface, the method includes: a) forming a background pattern and at least three fiducials on the first image bearing surface, wherein the background pattern is larger than a first printed image and the at least three fiducials are within an area formed by the first printed image; b) transferring a portion of the first printed image to a second image bearing surface; c) measuring a first residual image on the first image bearing surface, wherein the first residual image is a portion of the background pattern and the at least three fiducials remaining on the first image bearing surface after the step of transferring; and, d) calculating at least one calibration parameter for the printing system based on the measuring of the first residual image.
