Abstract
A dual beam laser diode scanning method for an ultrahigh speed laser printer is proposed and its feasibility is tested. Two separate laser beams are scanned simultaneously by one facet of a polygon mirror. By employing this method, power emitted from each laser and the rotation speed of the polygon mirror can be reduced to half, compared with those in single beam scanning systems. Spacing between two lines is compensated for by a sample-and-hold spot control method.
