摘要： An electrophotographic printing machine of the type in which an electrostatic latent image recorded on a charge retentive surface is developed with toner particles to form a visible image thereof. A Hybrid Scavengeless Development (HSD) developer housing designed to control toner emission by employing two internal capture[JMC16], external exhaust manifolds. The location of the two manifolds are placed above and below the upper and lower donor rolls respectively. The manifolds are mounted in position to improve emissions control as well as reductions in the flow needed to accomplish the task. The upper and lower manifolds are able to control the loose toner emitted by the housing and lower powder cloud, they cannot collect the toner released by the upper powder cloud. To prevent toner accumulation in the middle regions of the wire module, a manifold is incorporated as an integral part of the wire module frame. Finally, toner released in the region between the two donor rolls near the magnetic roll surface may be controlled by inserting a baffle.
