Abstract
A technique for achieving a smart start of scan (SOS) detector that is related with line scan timing on raster output scanners by expanding the available functions to include beam size and position. A start of scan detection system adapted to provide beam size and position control. The system includes a CPU, a data source and laser driver managed by the CPU, and a multiple element pre-patterned detector managed by the CPU and enabling a sensor pattern through which laser beams from the laser driver are passed and detected. According to a method for managing beam size and position in a image processing system, a multiple element pre-patterned detector adapted to enable a sensor pattern is provided wherein at least one laser beam is passed through said sensor pattern enabled by the multiple element pre-patterned detector, analyzed and used by the image processing system to adjust beam size and position.
