摘要： Reflex writing is a group of algorithms developed to maintain color registration in xerographic systems using multiple imagers. Unlike conventional imaging, in which the individual color separations are imaged based on events in a time domain, in a reflex write implementation sequential color separations are written based on events in the spatial domain. Once the initial color separation is written, the distance that color separation travels is tracked until the color separation is under the next imaging station, where the next color separation is written properly registered with respect to the existing color separation. The imaging system includes a raster output scanner imager for the black station and a light emitting diode bar for the color station. For each black scanline written the distance the belt travels is tracked by counting machine clocks, which are based on photoreceptor module drive roll encoder pulses and related to the belt travel, and when the black latent image scanline has traveled the known distance between the two imagers, the light emitting diode scanline is written registered with respect to the raster output scanner scanline.

摘要： A system and method for spatially matching the output of two imaging stations in an electro-photographic device by using a second order polynomial curve and a third order polynomial curve to approximate the non-linearity errors between the two imaging stations and using the second order polynomial curve and the third order polynomial curve to modify the frequency of a pixel clock.
