Abstract: An inkjet printer detects vibrations within the printer and compensates for the detected vibrations by adjusting a gap between the printheads and the media transport. Additionally, the inkjet printer detects media sheet heights that may cause damage as they pass through the print zone of the printer and adjusts the gap to enable the media sheets to pass through the print zone without contacting the printheads. A method of operating an inkjet printer so configured is also disclosed.

Abstract: Techniques for operating a digital printer that includes a media transport and an electronic imager disposed in a path of the media transport are presented. The techniques include: receiving an electronic image of a media sheet obtained by the electronic imager; identifying, from the electronic image of the media sheet, a print-prohibited region of the media sheet; generating a mask representing the print-prohibited region of the media sheet; and electronically storing in electronic persistent memory, in association with an identification of a type of the media sheet, a template comprising information regarding the media sheet type, where the template includes an identification of the print-prohibited region represented by the mask.

Abstract: A method of operating a printer iteratively performs printhead purges and test pattern analysis until either every printhead has a number of inoperative inkjets that is less than a predetermined threshold or a maximum number of iterations is reached. An error message is generated for each printhead having a number of inoperative inkjets that is greater than the predetermined threshold. The iterative performance of the printhead purges and test pattern analysis is performed automatically prior to the commencement of printing operations with the printer to remove subjective and time-consuming analysis by a printer operator.

Abstract: A processor identifies print defect locations where printing defects occur and a assigns different sensitivity values to different zones of a job image being prepared for printing by a printing engine. The processor changes the orientation of the job image to a revised orientation, relative to print media, to avoid locating one or more high-sensitivity zones of the job image in the print defect locations. The high-sensitivity zones are ones of the zones having a sensitivity value above a threshold sensitivity value. The printing engine prints the job image on the print media at the revised orientation.

Abstract: A layered structure, which may be used as a fuser member, comprises a first layer containing silicone; a second layer containing a fluoropolymer; and between the first and second layers, an adhesive layer comprising an aminosilane adhesive. In the layered structure, the second layer may additionally contain at least one of a polyamide-imide or a polyamide. Alternatively, or in addition, the adhesive layer may additionally contain fluoropolymer and at least one of a polyamide-imide or a polyamide.
