Abstract: A cleaning apparatus (70) for cleaning, e.g. a photoreceptor belt (10), including an ultrasonic transducer (110) located under the photoreceptor belt (10) which provides vibrational energy to the surface to separate toner particles (87), from the surface of the belt (10). The transducer is positioned such that it is located directly opposite the cleaning nip (88) formed by a brush (80) with the belt. The transducer (110) reduces the adhesion of the toner (87) to the photoreceptor surface, thereby allowing the brush (80) to operate at reduced interference and voltage. The reduced interference and voltage results in toner (87) being collected only at the very tips (81) of the brush fibers (86) thus, allowing more effective detoning of the brush.

Abstract: In a lubrication method, toner particles (40) are removed from the imaging surface (11), in an electrophotographic printing device, by a cleaning blade (20) and move away from the blade to be collected (at 60) and reapplied to the surface (11) so as to lubricate the blade. An apparatus for the method is also claimed.

Abstract: An apparatus for efficient cleaning of the imaging surface. The primary cleaner is a rotating collection roll located directly opposite from and on the other side of the imaging surface from the ultrasonic cleaning assist device. The ultrasonic energy is used to remove the toner from the imaging surface enabling attraction toward the biased collection roll. The ultrasonic energy decreases the amount of residual toner remaining after transfer. The residual toner that is not cleaned from the surface by the collection roll is removed from the surface by the rotating biased conductive brush, which is the secondary cleaner. The collection roll is contactless in that it does not come into contact with the photoreceptor. In another embodiment of the invention, the primary cleaner and the secondary cleaner are collection rolls with ultrasonic cleaning assist devices directly under each collection roll. The entire cleaning system is contactless.

Abstract: Un aparato para limpiar partículas de pigmento orgánico triboeléctricas negativas, de la superficie fotorreceptora sin la necesidad de un corotron de prelimpieza. Para eliminar las partículas residuales, un primer cepillo de limpieza, en la direccion de movimiento del fotorreceptor, está polarizado negativamente para eliminar el pigmento orgánico positivo (+) y cargar las partículas de pigmento orgánico negativas. Entonces, el segundo cepillo, en la direccion del movimiento del fotorreceptor, es polarizado positivamente para eliminar las partículas de pigmento orgánico negativo, residuales de la superficie a medida que el segundo cepillo hace contacto con la superficie.

Abstract: In an electrostatographic imaging device of the type forming a multilevel electrostatic latent image on a surface of the imaging member, and developing the multilevel electrostatic latent image with at least two types of toner, and a brush cleaner for removal of toner and debris remaining after transfer of the image to another surface, the brush is maintained in a condition loaded with a first toner type providing abrasive characteristics at the fibers of the brush, for abrading the photoreceptor for removal of toner of said second type.

Abstract: Method and apparatus for moving residual toner from a photoconductive imaging surface. The invention includes the provision of an electrically conductive brush used for redistributing the residual toner images over the imaging surface so that the toner can be more effectively removed from the surface by the developer system. The brush is electrically biased by means of an A.C. voltage such that not only is the toner dislodged it is also picked up by the brush from one area of the photo conductive surface and dropped it on another area. By proper selection of the A.C. and D.C. voltages the conductive brush can be simultaneously used for redistribution and uniformly charging the photoreceptor surface.
