Abstract

The air mass within a xerographic machine contains a certain amount of airborne toner which has been removed from the photoreceptor surface. It is desirable to reclaim this airborne toner so that it can be used in subsequent cycles. To accomplish this reclamation, the air mass at selected loca-tions is directed at a predetermined velocity through a pipe, or series of pipes of predetermined cross-section. The pipe(s) are made of a porous material with the pores of such size and shape that the great majority of toner particles cannot pass through them. Most of the air mass, however, passes through the pores to be vented to the outside air. The toner travels along the length of the pipe to be eventually deposited into a toner sump.
