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： An apparatus in which a latent image recorded on a member is developed with a developer material comprising at least carrier granules and toner particles. Toner particles are dispensed into the developer housing and mixed with unused developer material. The toner particles and developer material are advanced along an extended path so that the toner particles are gently mixed and triboelectrically charged to substantially the nominal level prior to contacting the latent image. A system of this type is particularly useful for toner particles requiring extensive gentle mixing to achieve the desired triboelectric charge.

摘要： Current density to copy substrates of varying widths if monitored and controlled in the electrostatic transfer unit of an electrostatic reproduction device. Current density through a copy substrate is appropriately adjusted to compensate for the presence of end leakage current effect to a receptor. Voltage supplied to a current generation unit in an electrostatic transfer unit is controlled independent of the characteristic properties of the copy substrate. Image reproduction quality is maintained in an electrostatic reproduction device even as the width of the copy substrate changes and in the presence of end leakage current effect.

摘要： An apparatus which transfers successive different color toner images from a photoconductive belt to a sheet. The toner images are in superimposed registration with one another. Transfer efficiency of successive toner images is improved by neutralizing the charge on the toner image prior to the transfer of the next successive toner image to the sheet. This is accomplished by passing the sheet with the toner image transferred thereto between upper and lower neutralization corona generators. The upper neutralization corona generator applies a charge on the toner image having an opposite polarity to the normal polarity of the toner image. The lower neutralization corona generator applies a charge on the backside of the sheet having the same polarity as the normal polarity of the toner image.

摘要： A pretransfer sheet feeding device for an electrophotographic printing machine that minimizes impact with and delivers a sheet to a photoreceptor at a desired tangential position. The sheet feeding device includes a selectively engageable drive nip and a biased baffle member which forms a buckle chamber. There is further a plurality of rollers located so as to provide substantially frictionless directional guidance to the sheet while also inducing a predetermined bend to the sheet so as to deliver the sheet to the photoreceptor. The pretransfer rollers are also moveable so that the angle of approach of a sheet can be adjusted based on sheet weight or other characteristics. Once the sheet is tacked to the photoreceptor in the transfer zone, the disengageable drive nip is released and the sheet is controlled by the photoreceptor so that speed mismatch is not a problem.

摘要： A transfer charging device is arranged with dual transfer-assist blades consisting of a pressure blade and a halo blade. The pressure blade is arranged for contacting and thereby urging a substrate against an image-bearing photoreceptor. The pressure blade is formed of a relatively conductive material. The halo blade is formed of a dielectric material. The halo blade is positioned between the transfer charging device and the pressure blade to shield the pressure blade from being charged-up by the transfer charging device.
