    摘要： A layered photosensitive imaging member is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane. The modification described is to form the ground plane surface with a rough surface morphology by an electroforming process which leaves the surface with a matte-like finish. Light reflected from the ground plane formed with the matte finish is diffused through the bulk of the photosensitive layer breaking up the interference fringe patterns which are otherwise later manifested as a plywood pattern on output prints made from the exposed sensitive medium.

    摘要： A layered photosensitive imaging member is modified to reduce the effects of interference within the member caused by reflections from coherent light incident on a base ground plane. The modification described is to form the ground plane surface by an electroforming process which leaves the surface with a black finish. Light incident on the ground plane is absorbed, eliminating the reflections which contribute to the interference effect at the imaging member surface.

    摘要： A printhead for printing ink includes a particulate filter manufactured from a polymer sheet such as a polyimide sheet. Filter openings within the particulate filter can be formed using a mask and a laser beam to ablate exposed portions of the polymer sheet. Embodiments of the present teachings can result in the formation smaller filter openings at a smaller pitch within the polymer sheet than, for example, stainless steel particulate filters, and thus more openings which cover a larger percentage of the filter surface for a given filter size, which can result in a reduction of fluid pressure within the printhead. Thus smaller filter openings for improved filtering of smaller particulates can be formed while maintaining a sufficient ink flow at a sufficiently low pressure within the printhead during operation.

    摘要： A method of manufacturing a printhead includes connecting an ink supply and driving electronics to a predetermined number of inkjet ejector sites. Each ejector site includes a fluid inlet and an electrical connector. The predetermined number of ejector sites connected to the ink supply and driving electronics is less than the total number of ejector sites available for use in the printhead.

    摘要： A method for forming an ink jet print head can include attaching a plurality of piezoelectric elements to a diaphragm, dispensing an interstitial layer over the diaphragm, electrically coupling a plurality of conductive elements to the plurality of piezoelectric elements, and curing the interstitial layer. A plurality of electrically isolated conductive particles within the interstitial layer electrically couple the plurality of conductive elements to the plurality of piezoelectric elements. The conductive particles can be evenly distributed throughout the totality of the interstitial layer dielectric, or they can be localized over a top surface of each piezoelectric element and interposed between the plurality of piezoelectric elements and the plurality of conductive elements. The conductive elements can be part of a flex circuit or printed circuit board.
