Abstract
A computer adapted to convert images into raw data can provide the raw data to a control interface adapted to transmit the raw data with timing information to an electronic driver circuit. The electronic driver circuit can convert the raw data with the timing information provided by a control interface into regulated current signals provided to the semiconductor laser array at 300 dpi and higher. The semiconductor array can convert the current signals into light to illuminate an imaging member. The laser array can comprise vertical cavity surface emitting lasers providing imaging greater than 300 dpi. Each semiconductor laser can operate at 50 mW or greater.
