Abstract
Positive form overlays are used to make composite images with a positive mode xerographic printer having a laser scan exposure mechanism. The laser scan or electronic exposure mechanism uses an oscillating galvanometer mirror to sweep a scanning spot over a cylindrical shape photoconductor. The xerographic processor includes a transfer drum able to recycle a sheet relative to the photoconductor to transfer at least two sequentially generated xerographic toner images to the same side of the same support in registration. One image is made in response to electronic signals and the other from the positive overlay thereby yielding a composite toner image.
