Abstract: A system and method for controlling the imaging device in a single pass multi color electrophotographic printing machine, comprising a photoconducti ve member defining a timing aperture, the member moving along a path in a 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, which generates a timing signal for each of the plurality of imaging devices as a function of the signal generat ed by the sensor and a plurality of predetermined parameters.

Abstract: Ein Drucker schließt eine Vielzahl von Punkttaktsignalgeneratoren ein, von denen jeder Punkttaktsignale zum Betreiben von Ausstoßvorrichtungen in einem Druckkopf in einer Farbstation des Druckers erzeugt. Die Punkttaktsignalgeneratoren sind in einer Kette verbunden, die der Prozessrichtung der Farbstationen im Drucker entspricht. Jeder Punkttaktsignalgenerator ist konfiguriert, um Punkttaktsignale eines vorherigen Punkttaktsignalgenerators in der Kette oder eines Referenztaktgenerators zu zählen, um zu bestimmen, wann der Punkttaktsignalgenerator eingeschaltet wird, und um Codierersignale zu zählen, die der Bewegung eines Substrats durch den Drucker entsprechen, um zu bestimmen, wann Punkttaktsignale für eine Farbstation zu erzeugen sind.

Abstract: PROBLEM TO BE SOLVED: To provide a system and method for controlling an image pickup device in a single-path multicolor electrophotographic printer. SOLUTION: The system has a photoreceptor belt 10 which regulates a timing aperture and moves along a path 12 of the printer, and a plurality of image pickup devices B each of which forms a latent image on the photoreceptor belt 10. The system also has a sensor, which is located adjacently to the photoreceptor belt 10, and detects the aperture when the aperture in the photoreceptor belt 10 passes through the sensor and generates a signal showing its detection. The system further has a controller 90 which generates a timing signal for each of the image pickup devices B as a function between the signal generated by the sensor and predetermined parameters.
