Abstract
A system and method to control imaging devices in a single-pass multi-color electrophotographic printing machine that includes a photoconductive member having a timing aperture, the photoconductive member moving along a path in the printing machine, and a plurality of imaging devices, each one of the plurality of imaging devices writing a latent image on the photoconductive member. The system further includes a sensor, located adjacent the photoconductive member, to sense the aperture in the photoconductive member as it passes the sensor and generate a signal indicative thereof and a control device and method that provides a timing signal for each of the plurality of imaging devices based on the signal generated by the sensor and a clock signal that is synchronous for all of the imaging devices.
