ABSTRACT:
This invention relates to a pyramid polygon scanner wherein the differential scan length between multiple beams can be eliminated by tilting the beams with respect to the photoreceptor surface. Then the beam with the shorter scan lengths when the beams are normal to the photoreceptor, travel a greater distance before they impinge on the photoreceptor. At the start or end of scan the scan angle is not zero, so the scan lengths for the beams with the larger travel distances are increased by the extra distance multiplied by the tangent of the scan angle. At the proper tilt angle, all scan lengths at the photoreceptor are the same. Since the angular scan rate of all the beams are always the same, over the entire scan, the scan lengths of the individual beams will always be the same, at any fraction of the total scan. Thus the information written onto the photoreceptor by the multiple beams will be in alignment for all simultaneous beams.
