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： Raster output scanners having piezoelectric-activated lens movers comprised of a mounting base, an electrically operated piezoelectric element connected to the mounting base, a flexible linkage having a lens mount, and a lens attached to the lens mount. The flexible linkage includes flexible arms that can flex in the predominate direction of motion of the piezoelectric element, but that are substantially rigid in another direction. The flexible linkage is mounted such that the flexible arms bias the lens toward the piezoelectric element. Expansion and contraction of the piezoelectric element, combined with the bias of the flexible arms cause the lens mount and its attached lens to follow the expansion and contraction of the piezoelectric element. The rigidity of the flexible arms hold the lens in the proper focal plane. Beneficially, the piezoelectric element is driven so as to compensate for scan line position errors.

摘要： A single pass highlight color printer is disclosed which utilizes two pairs of Raster Output Scan (ROS) systems mounted symmetrically about a common polygon motor assembly. Four identical optical systems are thus provided, 180.degree. apart with diode laser outputs directed from a ROS frame parallel and separated to allow the appropriate spacing for xerographic components situated adjacent the xerographic belt. Each ROS unit includes a 90.degree. mirror pair which is mounted on a roof mirror carriage which in turn is connected to a focus carriage via an adjustable guide system. The interaction between the focus carriage and the roof mirror carriage enables a skew alignment and process (beam steering) adjustment to be accomplished with a high degree of precision.

摘要： The velocity of a photoreceptor belt is measured by sensing the passing of illuminated slits in the belt, as the belt moves in a process direction. Two linear position sensors are positioned so as to view the passing of the illuminated slits. The sensors are aligned in a staggered configuration so that there is an overlap region. The slits are positioned so that as one slit is moving off of a downstream sensor, a second slit is moving over the upstream sensor. The output from an illuminated sensor is alternately switched to the second sensor. The sensor outputs are differentiated to provide an output signal representing a belt velocity. The velocity is compared to said velocity in the belt drive system and error signals generated to compensate for detected changes in the belt velocity.

摘要： An improved document scanning system is realized by using low mass mirrors as optical components. The mirrors consist of a pair of metal structures in honeycomb form sandwiched between a pair of glass skins. The mirrors have a greatly improved stiffness-to-mass ratio compared to conventional mirrors and provide relatively low mass in scan drive components, as well as improved system performance.
