    Abstract: A system for eliminating differential scan line bow from raster output scanners aligns at least the chief exit ray (66, 67) of each scanning light beam (61, 62) with the system axis (65). By aligning the chief exit rays to be essentially parallel to the system axis, the overall bow is reduced, and the bow of different scan lines (63, 64) is essentially identical. Thus, bowed scan lines from different stations in a multi-station printer, or from different passes in a multi-pass printer are generally identical and aligned.

    Abstract: Described herein is a color printer (100) which uses multiple linear arrays of surface emitting lasers of differing wavelengths and polarization states to simultaneously expose widely separated positions on at least one photoreceptor (130, 134). Each array is imaged by the same optical system (122) to the photoreceptor (130, 134). The multiple linear arrays can be closely spaced in a monolithic structure.

    Abstract: A raster output scanner (ROS) laser diode architecture enables a plurality of laser diodes (3,4,6 and 8), which produce light beams at separated wavelengths, to be spaced a convenient distance apart for a multistation printer, by arranging the diodes in a line that is parallel to the fast scan direction of the ROS. Wavelength discriminating optics (32,34,46) are used to separate and reflect the light beams reflected from a single ROS polygon mirror (24). These separated and reflected beams then expose their associated photoreceptors (58,60,62,64), or respective portions of a single photoreceptor, with a rasterized image that is subsequently transferred to a support medium such as plain paper and developed into an image.
