Abstract (en)
[origin: US4775874A] A magnetic mechanism is provided for a non-mechanical printer or copier device comprising a conveying channel through which a developer mix including magnetic components contained therein flows, so that a plug of developer mix is generated via the magnetic mechanism for closing the conveying channel. The conveying channel contains a rotatable drum containing a magnetic strip and the drum is arranged in the conveying channel such that the one wall of the conveying channel forms a narrow retaining gap together with the drum and the other wall of the conveying channel forms a significantly broader conveying gap together with the drum.
