Abstract

In an electrographic printing device a plurality of printing groups each have a respective plurality of developer stations. A plurality of toner reservoirs are each connected via a respective toner transport channel with one or more of the developer stations. Each of the toner reservoirs outside of the printing groups is stored in a respective toner transport unit. Each of the toner reservoirs is provided with a first circuit having a memory in which is stored at least a color filled into the respective toner reservoir. A respective second circuit with a memory is associated with each of the toner transport units. These memories have stored therein at least the respective toner color filled into the respective stored toner reservoir. A respective third circuit with a memory is provided for each developer station, the respective third circuit memory having stored therein at least a toner color filled into the respective developer station.
