Abstract: 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.

Abstract: 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.

Abstract: 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.
