ABSTRACT:
An imaging system comprising a source of light movable with respect to a writing element and projectable thereon to generate an image, a focusing system is provided for focusing a light source which generates a first beam of light of a wavelength selected to be actinic with respect to the writing element. At least a portion of the first beam of light is absorbed by the writing element. The apparatus comprises a material feeder to automatically supply donor sheets and receiver sheets independently to a writing platen or drum, and to selectively load and unload the donor sheets from superposition with the receiver sheet without disturbing the registration of the receiver sheet. Also included are components which contribute to the quality of the images generated, such as relatively inexpensive, low jitter transports and drives for the writing head and imaging drum. In particular, a lead screw assembly is proved which accommodates wear in the assembly without imparting any misalignment, backlash, or jitter to the writing head.
