  • Method and device for adjusting to a minimum value the toner supply to a developing station of an electrographic printing unit or copying unit
    Publication number: 20070036563
    Abstract: In a method to adjust the toner supply to a minimum value in a developer station of an electrographic printing or copying device in which charge images are generated on an intermediate carrier, the charge images being inked with toner at the developer station, a toner concentration is measured in the developer station via a toner marking applied on the intermediate carrier and inked with toner at the developer station. A measurement signal is generated. Dependent on the measurement signal, a supply of the toner to the developer station is regulated. The supply of the toner to the developer station is increased independent of the measured toner concentration upon an under-run of a minimum value of the toner supply per unit time into the developer station so that the transfer of the toner from the developer station to the intermediate carrier is increased.
