摘要： In a multi-color imaging method and apparatus utilizing a charging step between two image creation steps, a corona generating device performs two different functions in different passes of the photoreceptor. The printing system may be a single pass system where all of the colors are developed in a single pass or a multi-pass system where each color is developed in a separate pass. The charging step may have more than one charging application as in a split recharge system.

摘要： Spot on spot color images in a single pass using a light lens copier are enabled. Image exposure is accomplished using light/lens scanning of a multi-color original document together with simultaneous shunting. Using a special photoreceptor configuration and a sequence of image creation steps including the aforementioned simultaneously shunting and exposure step, balanced latent images are formed across the photoreceptor structure. By balanced is meant that latent images exist across both an overcoat layer of the photoreceptor and the rest of the photoreceptor. Such an arrangement precludes development of the image across the overcoat layer if the photoreceptor were to be moved past a development system. Thus, an electrostatic voltmeter used to read the surface potential in the image areas would read zero or near zero volts. Following formation of the a plurality of balanced images, each of the balanced images is, one at a time, caused to become unbalanced prior to its movement past an appropriate development system. Subsequent to the development of each image except for the last one, the imaged area of the photoreceptor is subjected to corona emissions for the purpose of leveling the charge thereon not completely neutralized by development of that images. The unbalancing steps are effected using low resolution exposure devices such as bars or ROS devices. Simultaneous scanning of the original document using a Raster Input Scanner (RIS) provides information which is used by an information processor system for controlling the output of a plurality of low resolution exposure devices.

摘要： A method and apparatus for achieving optimum optical contrast for detecting registration marks in a multicolor print black first color electrophotographic printing machine. A black mask having voids in the shape of a registration mark is formed on the photoreceptor. A high contrast color is then overwritten on the mask forming marks which indicate the position of the black image. A second method utilizes only the first recharge unit and the last developer unit. A registration mark is imaged by each imager and all of the latent image registration marks are developed with a single color high contrast toner. A sensor is then used to determine the relative position of the various color imagers and to send signals to the controller to make appropriate corrections.

摘要： An apparatus and method of adjusting an imager in an electrophotographic printing machine to correct for registration errors when forming a composite image. Registration errors are sensed by forming one or more target lines on the photoreceptor surface, detecting the center of the lines and controlling the operation of the imager in response thereto. In one embodiment, four LED print bars form a composite color image in a single pass. A photosensor is placed beneath the print bars; a narrow target line is formed on the belt surface a few scan lines before the start of an exposure frame. The center of the line is detected by circuitry connected to the sensor output which produces a signal corresponding to detection of the center of the target line. This output signal is generated for each of the three downstream print bars and a signal is applied to each print bar to start the image exposure sequence in registration with first image exposure. In a second embodiment, skew registration adjustments are enabled by forming two line marks at opposite ends of the photoreceptor, detecting the center of each mark and making the adjustments of the position of the downstream print bars based on time differences between detection of the generation of the two signals.

摘要： In a multi-color imaging apparatus, the voltage differential between developed and undeveloped areas of a charge retentive surface is reduced for precluding edge effect development. The developed areas correspond to charged areas on the photoreceptor while the undeveloped areas represent discharged or background areas on the photoreceptor. Development of the charged areas is followed by an erase step for reducing the voltage differential between the developed areas and the non-developed background areas prior to the next development step.

摘要： The present invention is an apparatus that develops a latent image recorded on a surface with toner. An electrically biased electrode member in the development zone between the photoconductive member and the donor roll detaches toners from the donor roll so as to form a toner powder cloud in the development zone. The electrical bias applied on the electrode member is an asymmetrical wave. Toner from the toner powder cloud develops the latent image.

摘要： An apparatus which develops an electrostatic latent image. A transport roll advances developer material from a chamber to a donor roll. The donor roll advances the toner particles to the latent image. The latent image attracts toner particles from the donor roll. In order to improve the speed with which toner particles removed from the donor roll are replaced, an alternating voltage is applied between the two rolls.The magnetic transport roll is driven to rotate at a surface velocity at least 2, but not more than 5 times that of the rotational surface velocity of the donor roll. Also, the compression pile height (CPH) vs the spacing between the spacing between the donor roll and the transport roller (DRS) is found to be optimal when meeting the ratio CPH:DRS=2:3.

摘要： An apparatus in which the triboelectric charge of developer material toner adhering to carrier is measured. In the development system, a magnetic roller transports developer material closely adjacent a donor roller. The donor roller is electrically biased relative to the magnetic roller so that toner is developed onto the donor roller. The instantaneous current flow electrically biasing the donor roller is integrated and is indicative of the triboelectric charge to the developer material.
