Current raster scanners use two separate crossover detector circuits for sensing the start and end of a scan line. Two separate pulses are produced, a start-of-scan (SOS) and an end-of-scan (EOS), one from each detector circuit, and are used to time the transfer of a scan line of data to the laser modulator.
