ABSTRACT:
A method and apparatus in electrophotographic printing for fusing a toner image onto or into a print medium. A high energy laser beam is projected onto a toner image on a print medium for softening or fusing the toner. Pressure is then applied to the toner against the print medium to permanently fix the toner image onto or into the print medium as a printed image. The high energy laser beam for softening or fusing the toner is synchronized in scan frequency, either at the scan frequency or a whole multiple of the scan frequency, with the low energy image modulated laser beam which scans to photoconductive drum, being reflected from selected facets of a common scanner, or from a selected facet of each of a pair of relatively angularly displaced interconnected scanners.
