摘要： A paper conditioner to control image dependent curl in a copier/printer includes a nip formed between metering and transfer rolls with grooves positioned on end portions of both of the metering and transfer rolls. Portions of both the metering and transfer rolls are located over a sump connected to a reservoir that supplies liquid to the nip for transfer to the transfer roll. The grooves act as gutters and allow excess liquid to flow into a sump, and subsequently, back into the reservoir. Flaps are positioning in the grooves in order to aid in the flow of fluid back into the sump.

摘要： A flexible imaging sheet and a method of constructing a flexible imaging sheet is disclosed. The method of constructing a flexible imaging sheet comprises a step of overlapping, a step of joining, and a step of shaping. In the step of overlapping, a first marginal end region and a second marginal end region of a sheet are overlapped to form an overlap region and a non-overlap region. In the step of joining, the first marginal end region and the second marginal end region of the sheet are joined to one another by a seam in the overlap region. In the step of shaping, the overlap region is shaped to form a generally planar surface co-planar with a surface of the non-overlap region. The flexible imaging sheet comprises a first marginal end region and a second marginal end region The first marginal end region and the second marginal end region are secured by a seam to one another in the overlap region. The first marginal end region and the second marginal end region are substantially co-planar to minimize stress on the flexible imaging sheet. Minimization of stress concentration, resulting from dynamic bending of the flexible imaging sheet during cycling over a roller within an electrophotographic imaging apparatus, is particularly accomplished in the present invention.

摘要： An apparatus in which an electrostatic latent image is developed with liquid toner. The apparatus has a liquid extruder that extrudes a thin film of liquid toner which is attracted to the electrostatic latent image forming a liquid image on a photoconductive surface. The extruder is electrically biased to a suitable magnitude and polarity to ensure that the liquid toner is attracted to the latent image. A vacuum is applied on the liquid toner as it is being attracted to the latent image so as to reduce the thickness of the layer coated thereon.

摘要： An electrophotographic printing machine utilizes an improved image registration system that forms and senses image registration indicia to control a subsequent transfer of a visible image. A first transfer station transfers registration indicia, previously formed on a first photoconductive member and transferred therefrom, onto a receiving member. A sensor monitors the registration indicia on the receiving member and generates a control signal indicative thereof. A second transfer station, responsive to the control signal, transfers a visible image, previously formed on a second photoconductive member and transferred therefrom, to the receiving member.

摘要： A rapid warm-up fuser roller (and fusers and marking machines that use such a fuser) comprised of a metallic cylindrical core, a thermally and electrically insulating layer of volume graft over the metallic core, a resistive heating layer over the insulating layer, and electrical connections to the resistive heating layer such that electrical current passing through the electrical connections flows through the resistive heating layer in a direction that is substantially parallel to the axis of the metallic core. The electrical current causes the resistive heating layer to heat while the insulating layer of volume graft enables rapid warm-up of the roller.

摘要： A Liquid Immersion Development, LID, reproduction machine having a moving liquid toner image carrying surface, includes an excess carrier liquid removing apparatus. The excess carrier liquid removing apparatus includes a housing defining a chamber, and an opening through the housing into the chamber for mounting against the liquid toner image carrying surface. The excess carrier liquid removing apparatus also includes a roller mounted rotatably to the housing and within the chamber for forming an image processing nip gap, that has an image entrance side and an image exit side, with the liquid toner image carrying surface. The excess carrier liquid removing apparatus further includes an air pressure creating device associated with the chamber for creating an air pressure differential within the chamber and across the image processing nip from one to the other of the entrance and the exit sides, in order to desirably affect flow of carrier liquid through the nip with minimal carrier liquid vaporization and with no liquid toner image disturbance.

摘要： A xerographic printer or digital copier has an intermediate belt for transferring images from several photoreceptive drums to sheets of paper. The intermediate belt experiences undesired stretching and shrinking which results in the size of the transferred image being distorted and the colors of the transferred image being misregistered. The printer is provided with a plurality of drag inducing members preferably in the form of drag rollers or skid plates which minimize the stretching and shrinking of the intermediate belt by counteracting the belt distorting forces. The magnitude of the drag forces to be applied by each of the drag inducing members can be calculated and the position of each of the drag inducing members can be adjusted according to each of the calculated drag forces.
