Raster output scanner with a field replaceable collimator assembly

摘要

A raster output scanner is disclosed which utilizes a collimator assembly which can be replaced at the field. The collimator assembly is mounted on a raster output housing. Both the raster output housing and the collimator assembly have securing means to secure the collimator assembly to the raster output scanner housing. The raster output scanner housing and the collimator assembly are designed to provide automatic adjustment for the light beam exiting from the collimator assembly with the optical path within the ROS housing once the collimator assembly is secured to the raster output scanner housing.
