Abstract: A device and method for determining and applying a transfer voltage in an imaging apparatus is provided. A servo voltage is determined based in part upon a change in an environmental condition. A determination is made whether or not to perform a new transfer servo operation based upon at least one of an amount of time passing since the last transfer servo operation was performed and a comparison of the determined servo voltage and a servo voltage used in a prior transfer servo operation. A transfer servo operation includes charging a photoconductive drum to a charge corresponding to a printing voltage.
