Abstract: A donor roll for transporting marking particles to an electrostatic latent image recorded on a surface is provided. The donor roll includes a body rotatable about a longitudinal axis and an electrode member. The electrode member includes a plurality of electrical conductors mounted on the body with adjacent electrical conductors being spaced from one another having at least a portion thereof extending in a direction transverse to the longitudinal axis of the body.

Abstract: A method for manufacturing a fibrillated pultruded electronic component includes the steps of providing a rod comprising a plurality of conductive fibers embedded in a matrix material, the rod having a first end and a second end. The rod is rotated and a liquid is sprayed onto the rod at a distance from the first end of the rod. The matrix material is abraded away from between the fibers of the rod. The fibers of the rod are then cut. A disk is formed which has a plurality of conductive fibers embedded in a matrix material. However, the ends of the disk include only the conductive fibers and not the matrix material. This enables the ends of the disk to have a fibrillated brush-like structure which is particularly well suited for low energy electronic/microelectronic signal level circuitry typified by contemporary digital and analog signal processors.

Abstract: A developer unit adapted to develop a latent image with toner particles. The unit includes a housing defining a chamber for storing a supply of toner particles in the chamber. The unit also includes a donor roll including an electrically non-conductive circumferential surface having a conductivity less than 10.sup.-8 (ohm-cm).sup.-1 and having a central region and opposed marginal regions disposed on either side of the central region with the diameter of the central region being less than the diameter of the opposed marginal regions. The donor roll is spaced from the latent image to form a development zone. The unit further includes an electrode member which is positioned in the development zone adjacent opposed marginal regions and spaced from the central regions of the donor roll. The electrode member is electrically biased to detach toner particles from the donor roll to form a toner powder cloud in the development zone with toner particles from the toner cloud developing the latent image.

Abstract: A xerographic printer especially suitable for printing copies of oversized original documents is enabled by staggering a plurality of image bars in optical alignment with a linear projection means such as gradient index lens arrays which are tilted at a preferred angle. The image bars are selectively addressed in response to digitized bit-mapped data inputs representing the document information. The modulated light outputs from the bars are transmitted as focused lines on the surface of the photoreceptor. The printer includes illumination lamps and a lamp aperture which parallels the staggered image bars. Further, a multi-function copier/printer is realized by combining a variation of the xerographic printer with a conventional imaging system for copying a document.

Abstract: A printhead for electrostatic printing comprises a membrane, made of a non-crystalline ceramic material, defining a first surface and a second surface, and defining a plurality of apertures therein. A plurality of addressable segmented electrodes are disposed on the first surface around substantially the periphery of an aperture on the first surface, each segment of the addressable segmented electrodes being isolated from each other segment. A conductive layer is disposed on the second surface around substantially the periphery of at least one aperture on the second surface. The ceramic membrane facilitates the incorporation of active electronic devices on the printhead.
