Abstract: A high velocity air and stationary disturber cleaner for cleaning surfaces by drawing air under flexible film seals. A vacuum enclosed in a housing provides the suction force to draw the air under the seal, tangent to the surface to be cleaned, thus removing adhered particles. Disturbers are placed on the surface of the seals in contact with the surface to be cleaned to loosen particles to be removed. The brush density, the fiber length and a plastic film incorporated into the brush design are all ways to limit the amount of air flow through the bulk of the brushes for better cleaning efficiency.

Abstract: An ion printing head is provided with a pin array coronde as an ion generation device, a corona controlling electrode and an array of modulation electrodes controlling the flow of ions to an imaging member in imagewise configuration. The pin array coronode provides an efficient and highly directable source of ions. At least part of the directability of the ions appears to be a result of the highly directionalized ion or corona wind, that tends to flow in a direction defined by the plane of the coronode. The corona wind also serves the purpose of removing corona effluents from the area adjacent the coronode that eventually cause deterioration of the head parts.
