Abstract

A printing apparatus for use in a printer with a photo-sensitive drum. The printing apparatus includes a spotlight source for generating a light provides essentially a point source. A fiber-optical converter which is optically coupled to the spotlight source converts the light from the spotlight source to linear rays of light. A plurality of shutter window optically coupled to the fiber-optical converter selectively transmits the light at selected portions of the array to the photo-sensitive drum. As a result, a light path is defined from the spotlight source through the fiber-optical converter and the microshutters to the photo-sensitive drum.
