ABSTRACT:
The invention relates to a device for the reintroduction of solid developer particles, which have been separated from a gaseous carrier flow, into a reservoir that is open to the air. The derive (60) is disposed between the reservoir (15) and the apparatus (26) for separation and recovery of particles, and it includes a chute (61) into which the discharge conduit (47) of the apparatus discharges. A transport element (65) that slides inside the chute (61) isolates the discharge conduit from ambient atmospheric pressure. This transport element is provided with a cavity (67) in which the particles that drop into the conduit accumulate, and the accumulated particles are then transported outside the chute and drop into the reservoir (15). The invention is applicable to non-impact printing machines.
