Paper Abstract

The desire to print high quality, highlight color documents at production rates has brought on the need for a single-pass highlight color laser scanner. We examine a pulsed-imaging, pulse-width-modulated polygon laser scanner that enables multilevel exposure and subsequent development of black and highlight color toner. As currently used in the Xerox 4850 digital printer, this scanner writes three different exposure levels; no exposure, mid-level exposure and high exposure for black, white, and highlight color, respectively. In this paper we review the functioning of a pulsed-imaging scanner and then examine how it is used in a pulse-width-modulated trilevel mode. A linear-systems model is used to examine the specialized video required for achieving uniform line appearance for both black and highlight color. This model further describes how image enhancement is enabled. A complete laser/xerographic model is used to simulate the output.
