Abstract: A method for achieving high resolution printing using low resolution LED bars is performed by arranging the bars at particular angles to the photoreceptor and timing the activation of the pixels within the LED bars according to the movement of the photoreceptor. In addition, the LED bars may be segmented and arranged so that the segments abut one another at different locations. Each of the abutting segments is disposed at a particular angle to the photoreceptor in the process direction. A lens arrangement is used to image the LED bars.

Abstract: A fiber optic system is used in a laser ROS scanning system to generate a start of scan signal. In one embodiment, a single optical fiber is positioned at the beginning of a scan line sweep. The fiber transmits a portion of a scan beam energy to a photodetector located on a local electronics board. The photodiode generates an output signal which is sent as an input to a high speed comparator. A second input to the comparator is a divided down and delayed analog of the photodetector output signal. The comparator compares the two voltage wave forms and generates electrical signals at the precise time the two wave forms intersect or crossover. The comparator output is used to initiate the SOS signal of a gas or laser diode ROS.

Abstract: The present invention provides a means and method for efficiently and automatically monitoring and adjusting the power output of either a single or a dual beam laser diode array used to provide the scanning beams in a ROS system. Collimated light outputs from a collimator lens assembly following either a single or dual beam laser are reflected along an optical path to impinge on one or two photodiodes positioned so as to intercept the reflected light. The photodiode output is proportional to the power output of the laser diode associated with the photodiode. In one multi-beam embodiment, polarization of the laser diode output is controlled so as to ensure that only outputs from an associated laser diode is sensed by an associated photodiode. In another embodiment, a half wave plate is used to rotate the polarization of one of the laser diodes.

Abstract: The present invention presents an apparatus and method for efficiently and automatically monitoring and adjusting the power output of laser diodes used to provide the scanning beams in a ROS system. Light radiated from the back facet of the laser diode is directed onto at least a pair of back facet photodiodes. The photodiode outputs are proportional to the power output of the laser diode associated with the photodiode. The polarization of the laser diode back facet output is controlled so as to ensure that the only outputs from an associated laser diode is sensed by an associated photodiode. In one embodiment, a half wave plate is used to rotate the polarization of one of the laser diodes and in another embodiment optical fibers efficiently transmit light emitted from the back facets to the photodiode.

Abstract: A raster output scanner is capable of creating images at a wide range of selectable resolutions. A laser source for creating an image is modulated at a pixel clock rate. A clock command value is determined as a function of a value related to the pixel clock rate and a value related to a desired resolution in the fast-scan direction and a desired resolution in the slow-scan direction of an image to be created on the photosensitive surface. The pixel clock rate is controlled in response to the clock command value. A polygon command value is determined as a function of the value related to the pixel clock rate, a value related to a desired resolution in the fast-scan direction of an image to be created on the photosensitive surface, and a value related to a rotational velocity of the polygon mirror. The rotational velocity of the polygon mirror is controlled in response to the polygon command value.

Abstract: A system and method to provide 180-degree rotation of image data at full throughput. The system includes a memory access controller that writes bursts of image data into a rotation buffer. The image data is then read out of the rotation buffer in the reverse order from which it was written to thereby accomplish rotation. By alternating the position in the rotation buffer in which the image data is written such that an image is either written into the buffer from top and read from the bottom or written into the buffer from the bottom and read out from the top, a one page rotation buffer of can be used to concurrently process two pages.

Abstract: A control system for a ROS scanner in which the aspect ratio and magnification of an image is controlled by precise, real-time control of the relative velocities of the polygon mirror and the photoreceptor. Values related to monitored measurements of polygon mirror and photoreceptor velocity are mathematically combined with a reference clock value and other factors to yield real-time control signals. The control signals operate the polygon and photoreceptor motors to obtain a desired magnification and aspect ratio of images created on the photoreceptor.
