Abstract (en)
[origin: WO8902616A1] A device is disclosed for pneumatically filling a toner reservoir (10) with toner (23) from a transport container (22). From the reservoir (10), the toner (23) is then supplied to the developing station (11) of an electrophotographic printing machine. The filling device has a deposit chamber (12) that communicates with the developing station (11) and a suction chamber separated from the deposit chamber (12) by filtering means (14) and provided with associated, vacuum-generating means (19). The deposit chamber (12) is provided with a scraping device (28) that detaches with elastic scraping elements (28) the toner deposited on the filtering means (14).
