Abstract

Figure 1 shows a section of a printing system which uses a rotating polygon 10, wherein a fixed external mirror 12 is used to redirect a laser beam 14 back to the facet 16 of the rotating polygon. Since the reflected beam has twice the mechanical scan of the facet, the second beam has twice the scan angle of a single reflected beam.
