    摘要： An imaging system for effecting electrostatic printing of an image, wherein the imaging system includes at least one contact electrostatic printing engine operable in a novel fashion upon a copy substrate, for imaging and development of an electrostatic latent image representative of the image, and subsequently transfers the developed image to the copy substrate. A toner cake delivery apparatus provides a thin, uniform toner cake layer of high solids content to a suitable receiving member for subsequent pressure contact with the surface of a latent image bearing imaging member such that a developed image is created by separating and selectively transferring portions of the toner cake layer in correspondence with the image and non-image regions of the latent image.

    摘要： A method and device for sensing spatial variations and/or temperature variations in the locality of a fiber optic cable 1 is disclosed, wherein a broadband light source 47 is used to shine incident light onto a series of fiber Bragg gratings contained within zones A, B and C. Each zone contains a plurality of fiber Bragg gratings, the plurality of fiber Bragg gratings in any one zone having a substantially identical grating period, and the fiber Bragg gratings in the respective zones having different grating periods. The reflected light from each fiber Bragg grating is returned back down the fiber optic cable 1 and redirected via a 2×1 coupler 51 to a wavelength detection system 53 and a personal computer 63. The combination of wavelength detection system 53 and personal computer 63 allow analysis of the reflected light patterns, as well as providing a user interface which enables detection of the occurrence of a spatial and/or a temperature variation. The location of the said variation along the fiber optic cable 1 is advantageously detectable in terms of the particular zone A, B or C in which the said variation has been sensed.

    摘要： A multicolor image-on-image reproduction machine includes a main assembly, a controller, a movable image bearing member having a path of movement, and a plurality of air breakdown charge and development (ABCD) imaging units mounted along the path of movement for forming color separation toner images. Each (ABCD) imaging unit includes a photoreceptor having a photoconductive surface forming a toner image separation development nip with the movable image bearing member; a toner supply apparatus for applying a layer of toner onto the photoconductive surface; a charging device for uniformly charging the photoconductive surface through the layer of toner; and an exposure device connected to the controller for image-wise exposing of the photoconductive surface and the layer of toner to form therein image areas and background areas of a desired color separation image. The multicolor image-on-image reproduction machine then includes a bias source for biasing the image bearing member at the toner image separation development nip to a potential sufficient to cause air breakdown selective recharging of the background areas of the layer of toner, thereby enabling the image areas of the layer of toner to be separated and developed as a color separation toner image onto the movable image bearing member, and the background areas thereof to remain on the photoreceptor.

    摘要： An imaging system for effecting electrostatic printing of an image, wherein the imaging system includes an electrostatic printing engine operable in a novel fashion upon a copy substrate, for imaging and development of an electrostatic latent image representative of the image, and subsequently transfers the developed image to the copy substrate. A quantity of low solids content liquid developing material is subject to compression in a process nip such that the concentration of marking particles therein increases and the concentration of carrier fluid decreases. A toner cake layer is thereby formed in the process nip, and is used for development of the electrostatic latent image in a development zone situated in the process nip.

    摘要： The efficient contact transfer of liquid toner images is obtained by using an absorbent coating material over an image bearing member. The absorbent coating material absorbs carrier fluid from a developed image. By absorbing carrier fluid from the developed image the internal cohesiveness of the image increases and the adhesion of the image to the next substrate increases.
