Abstract
A pair of lenses, side by side, create twin optical paths for image projection from a single object station to twin photoreceptor drums, rotating in opposite directions. The lens pair, as it moves back and forth, is scanning in both directions and alternately projecting onto one and the other of the two photoreceptors.
