Disclosed is a micro-vacuum cleaner blade system or MVCB that reduces or eliminates build up of toner on a photoreceptor surface during open platen or other high photoreceptor area coverage exposure and development. The micro-vacuum cleaner blade system, as shown in Figure 1, is comprised of a cleaner housing 1 for cleaning photoreceptor surface 2, a disturber brush 3 and associated flicker bar, a cleaning blade 4 in doctor mode, a paddle 5 and paddle seal 6, which cooperate to remove and convey toner from the photoreceptor surface 2 to a conveying auger member 7. During heavy cleaning events, for example, open platen development, the conventional system may become overwhelmed by excess toner and cleaning efficiency may deteriorate unacceptably. As shown in Figure 2, addition of a vacuum housing or manifold assembly 8 can effectively remove excess toner prior to the waste toner contacting the cleaning blade 4 sweep. The excess toner is removed via the vacuum manifold 8 through holes 9 and transported to, for example, a replaceable filter bag by way of transport tubing 10 within the vacuum manifold.
