摘要： An imaging device for producing multicolor images from image data containing data representing an image of a first color and an image of a second color to be registered relative to the image of the first color onto a substrate by transferring toner of the first and second colors to the substrate is provided. The imaging device includes a first imager, a second imager, a photoreceptor belt, a plurality of rollers mounted to a frame of the imaging device, an angular position sensor, an image data source and a controller. The plurality of rollers define a process path along which the photoreceptor belt is driven past the first and second imagers in a process direction. The plurality of rollers includes a drive roller that exhibits an eccentricity for which a formula relating angular position as a function of the phase angle of the drive roller to eccentricity is known. The angular position sensor detects the phase angle of the drive roller. The image data source generates image data that includes a line to be printed in the first color and in the second color. The controller is coupled to receive signals from the angular position sensor, ROS imager and image data source and is configured to drive the second imager to generate an optical output. The controller includes memory and a processor. The memory stores the formula relating angular position as a function of the phase angle of the drive roller to eccentricity. The processor calculates an appropriate time delay for starting the generation of the optical output of the second imager for printing the line to be printed in the first color and in the second color based on the time of the starting of the optical output by the ROS imager to print to print that line, the signal received from the angular position sensor, and the formula relating angular position as a function of the phase angle of the drive roller to eccentricity.

摘要： Color electrophotographic printers having latent image positions synchronized with start-of-scan signals. A laser source projects a laser beam onto a multifaceted rotating polygon that sweeps that beam in a scan line across a moving photoreceptor. A start-of-scan detector produces start-of-scan signals when the laser beam is in position to write a scan line. A belt sensor produces belt signals when indicia on the photoreceptor passes a reference position. A controller receives the belt signals and the start-of-scan and then adjusts the photoreceptors rotational velocity such that the belt signals are an integral multiple of the start-of-scan signals. To reduce the impact of drive roller eccentricities on belt signal to start-of-scan signal timing, the perimeters of photoreceptor roller elements are sub-multiples of the photoreceptor length.

摘要： A method and apparatus for simultaneously developing and transferring a liquid toner image. The method includes the steps of moving a photoreceptor including a charge bearing surface having a first electrical potential, applying a uniform layer of charge having a second electrical potential onto the charge bearing surface, and imagewise dissipating charge from selected portions on the charge bearing surface to form a latent image electrostatically, such that the charge-dissipated portions of the charge bearing surface have the first electrical potential of the charge bearing surface. The method also includes the steps of moving an intermediate transfer member biased to a third electrical potential that lies between said first and said second potentials, into a nip forming relationship with the moving imaging member to form a process nip. The method further includes the step of introducing charged liquid toner, having a fourth electrical potential, into the process nip, such that liquid toner sandwiched within the nip simultaneously develops image portions of the latent image onto the intermediate transfer member, and background portions of the latent image onto the charge bearing surface of the photoreceptor.
