Abstract
In a method and system for operation of a transfer printing station of an electrographic printing device, a transfer printing station is provided comprising a light-sensitive medium onto which toner images are provided by electrostatic forces affected via a toner image electrical potential. A transport band is provided holding successive sheet-form recording medium by electrostatic forces. Toner images are transfer printed from the light-sensitive medium onto the successive sheet-form recording media by electrostatic forces affected by an electrical transfer printing potential. The electrical transfer printing potential is at least reduced while the light-sensitive medium passes into intervening space line between two successive recording media sheets. A cleaning station cleans off residual toner on the light-sensitive medium that is not transfer-printed. A cleaning device mechanically loosens residual toner from the transport band. A toner quantity sensor is provided for at least one of a residual toner reservoir of the cleaning station and a residual toner reservoir of the cleaning device. The sensor provides an operator an indication to exchange at least one of the residual toner reservoirs.
