Abstract
Abstract A color electrophotographic printing machine, wherein an electrostatic latent image recorded on a photoconductive member is developed with toner of a first color and toner of a second color to form a visible image thereof, the electrophotographic printing machine including a system, for removing contaminates from toner of a first color and toner of a second color moving from a toner dispenser to a developer housing, the system including: a mounting assembly, a filter system mounted on the mounting assembly, the filter system having a screen for permitting toner of the first color to travel therethrough while inhibiting contaminants from traveling therethrough when vibrated; a first vibration driver, operatively connected to the screen, for vibrating the screen; a second filter system mounted on the mounting assembly, the filter system having a screen for permitting toner of the second color to travel therethrough while inhibiting contaminants from traveling therethrough when vibrated; and a second vibration driver being operatively connected to vibrate the screen, and coacting with the first vibration driver, for damping ocillation of the mounting assembly.
