Abstract

A line-at-a-time printer is realized by directing a collimated light beam through an interaction area of an electro-optic light modulator while successive sheets of data samples are sequentially applied to electrodes positioned across the width of the modulator. A modulated line latent image is formed on the surface of a photoreceptor, the photoreceptor being indexed to create successive exposed, modulated line images on its surface. Electronic registration control of successive images, for example in a color printing process, is achieved by a control system which triggers the light beam source between the time interval during which data signals are loaded into the modulator. In one embodiment the pulse sourcing is accomplished through a feedback loop which includes a sensor for monitoring movement of the photoreceptor and application of the light source pulses and the data samples.
