PCT No. PCT/DE87/00442 Sec. 371 Date Apr. 3, 1989 Sec. 102(e) Date Apr. 3, 1989 PCT Filed Sep. 25, 1987 PCT Pub. No. WO88/02505 PCT Pub. Date Apr. 7, 1988.In a toner transfer system of a printer or copier, a suction nozzle inside a toner-tight protective sheath is arranged in verticallly displaceable fashion in a guide in the printer or copier, this suction nozzle being in communication via a pipe line with a developer station of the printer or copier. At it slower end, the guide has an adaptor for connection to a toner container. When the toner container is to be changed, the toner container is swivelled via a holding mechanism and a new container is connected to the adaptor. A cutter on the adaptor then punctures a sealing foil over the filling and emptying opening of the toner container. For emptying, the suction nozzle moves vertically into the toner container whose floor is fashioned funnel-shaped to form a toner collecting region. |
