ABSTRACT:
An imaging system having a source of light movable with respect to a writing element and projectable thereon to generate an image, a focusing device is provided for focusing a light source which generates a beam of light of a wavelength selected to be actinic with respect to the writing element. At least a portion of the beam of light is absorbed by the writing element. The apparatus includes an imaging drum for holding donor sheets and receiver sheets in registration on the drum. A registration device including a non-reflective indicia on the surface of the drum facilitates the proper registration of the donor and receiver sheets.
