Paper Abstract

The design, construction and general characteristics of a triple function machine are described. The digitized raster input and output scan are produced by a polygon type flying spot laser scanner. The optical system is the underfilled, double pass type with anamorphic scan line wobble correction. In order to further enhance pixel placement accuracy, an advanced type of Polygon Signature Correction and a Motor Hunt Correction technique were developed and implemented. The scan head is built into a standard Xerox 3107 copier in such a fashion that the conventional photocopy function is retained. The coupling of the two optical systems was made possible by the inherent compactness of the scanner that permitted the sharing of the optical path. Document "reading" in the input scan mode is accomplished by a concave mirror type light collector, coupled with a small Photo Multiplier Tube.
