Abstract
A computer controller for a raster output scanner. The software consists of an operating system and application programs. Each application program acts as a servo loop and controls such operating variables as the laser diode input power, output light intensity and temperature, and polygon speed. The operating system receives the current values of these variables, compares them against ranges limits and will inform the operator of malfunctions or needed maintenance in addition to managing the more typical computer functions such as driving peripherals and managing memory. The entire software system is generalized to the point where it can calibrate and maintain any ROS, and therefore need not be redesigned for different ROS products. In addition, when hardware parts are replaced, the operating system can change the operating ranges instead of replacing the programs.
