Abstract
A full color digital scanning system includes a lamp carriage having a light source and a mirror. A mirror carriage is also included with a rotatable corner mirror assembly. The rotatable corner mirror assembly has a first color corner mirror subassembly, a second color corner mirror subassembly, and a third color corner mirror subassembly. The scanning system positions a first color corner mirror on a mirror carriage to provide a 180.degree. cornering function and scans the image to produce image data representing a first color component. The scanning system then positions a second color corner mirror on the mirror carriage to provide a 180.degree. cornering function and scans the image to produce image data representing a second color component. The scanning system further positions a third color corner mirror on the mirror carriage to provide a 180.degree. cornering function and scans the image to produce image data representing a third color component.
