Patent ID: 7555246

Claim:
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, comprising: a housing having a supply of toner and developer therein; a donor member for transporting toner from said housing to a development zone; a first manifold, adjacent to said donor member, having an air stream for removing toner emission: a second manifold, adjacent to said donor member, having an air stream for removing toner emission; and a cyclone separator system, connected to said first manifold and said second manifold, for separating the toner from the air stream and returning toner particles of a predefined size back into said housing, said cyclone separator system includes a staging area for collecting toner particles of said predefined size after the air stream with toner emission has been processed.
