Patent ID: 7376365

Claim:
A method for operation of a transfer printing station of an electrographic printing device, comprising the steps of: providing a transfer printing station comprising a light-sensitive medium and adhering onto the medium successive toner images by electrostatic forces that are affected via a toner image electrical potential; providing a transport band and holding respective successive sheet-form recording media by electrostatic forces on the transport band, and transfer printing the toner images from the light-sensitive medium onto the successive sheet-form recording media by use of electrostatic forces that are affected by an electrical transfer printing potential opposite said toner image electrical potential, and at least partially deactivating the electrical transfer printing potential while the light-sensitive medium passes an intervening space lying between two successive recording media sheets; generating a toner marking on the light-sensitive medium; with a cleaning station, cleaning off residual toner provided on the light-sensitive medium that is not transfer-printed, and a residual toner reservoir of the cleaning station accepting toner particles cleaned off the light-sensitive medium; with a cleaning device provided at the transfer band, continuously mechanically loosening residual toner from the transport band, the residual toner falling into a residual toner reservoir associated with the transport band; and arranging a toner quantity sensor for at least one of the two residual toner reservoirs and emitting to an operator a request to exchange both residual toner reservoirs when the toner quantity sensor emits a full signal.
