<p>Imaging offset problems in image systems (100), such as electrophotographic 'EPG' printers and copiers, are overcome. Imaging offset results from misaligned exposure units that, when uncompensated, produce dots on a photoreceptor belt (106) at exposure positions that are offset from ideal dot positions. An imaging-offset compensating method of the invention first determines the imaging offset, which is a distance that may include a magnitude and a direction. The imaging offset is determined with respect to the ideal dot position. A time factor is then determined based on the magnitude of the imaging offset for each exposure unit. The time at which each exposure unit is actuated is modified by a respective time factor so that a dot produced by each exposure unit matches the ideal dot location thereof.</p> |
