Abstract

A device for the electrophotographic production of image patterns has at least one printing unit to which toner is supplied and has an arrangement for transferring used toner from a cleaning station of the printing unit to a used toner container. The arrangement for transferring can be interrupted to enable changing the used toner container without interrupting the printing operation of the device.
