ABSTRACT:
A method of converting existing copiers to laser printer engines by externally attaching an apparatus to the copier with no significant alteration of the copier engine, and attachable in an easily removable manner. The apparatus consists of a laser together with an optical system having means for modulating and scanning the laser beam, which enters the copier and passes through the copier's existing imaging lens. The apparatus incorporates a specially designed field mirror that simplifies that optical system.
