Abstract
This invention relates to an efficient way to calibrate and control a raster output scanner (ROS). The scan non-linearity of a ROS may be measured and an appropriate calibration curve setting for the ROS may be determined. The setting and other scan line parameters may then be used as an address to a memory, such as a read-only memory (ROM). The memory may store a set of calibration curve data and the address is used to look up the data from one of these curves. The ROS may then be controlled based on the calibration data retrieved from memory.
