ABSTRACT:
A xerographic reproduction machine for producing toner particle copy images of original images on sheet substrates includes a machine frame; a movable image bearing member mounted within and to the frame, the image bearing member having an image bearing surface defining a path of movement thereof. The xerographic reproduction machine also includes xerographic imaging elements mounted at various distributed locations along the path of movement for forming toner particle copy images of original images on the image bearing surface; devices for transferring the toner particle copy images onto sheet substrates for fusing; and an impulse air ejector cleaning system for intermittently purging and cleaning particulate dirt from sensitive elements among the electrostatographic imaging elements. The impulse air ejector cleaning system includes plural air lines, each of which has an air ejection nozzle positioned at a distributed location for directing air therefrom onto a sensitive xerographic imaging element at such location; a container containing pressurized air connected to each air line of the plural air lines; and a control assembly including a quick exhaust valve connected to the plural air lines, for controllably and intermittently releasing blasts of pressurized air from the container through each of the nozzles for purging and cleaning particulate dirt material from surfaces of sensitive xerographic imaging elements.
