Control system for aspect ratio and magnification of a raster output scanner |
摘要 |
A control system for a ROS scanner in which the aspect ratio and magnification of an image is controlled by precise, real-time control of the relative velocities of the polygon mirror and the photoreceptor. Values related to monitored measurements of polygon mirror and photoreceptor velocity are mathematically combined with a reference clock value and other factors to yield real-time control signals. The control signals operate the polygon and photoreceptor motors to obtain a desired magnification and aspect ratio of images created on the photoreceptor.
