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, including: a housing having a supply of toner and developer therein; a donor member for transporting toner from the housing to a development zone; a first manifold, adjacent to the donor member, having an air stream for removing toner emission; a second manifold, adjacent to the donor member, having an air stream for removing toner emission; and a cyclone separator system, connected to the first manifold and the second manifold, for separating the toner from the air stream and returning toner particles of a predefined size back into the housing.
