A transfer printing station is provided with a transfer roller for
transfer of a toner image generated on an intermediate carrier onto at
least one recording medium in a transfer printing region of the transfer
printing station. A drive unit causes the transfer roller to move towards
the intermediate carrier as an ON position or away from the intermediate
carrier as an OFF position, the drive unit being designed such that it is
position-controlled when moving towards the ON position, and is torque
controlled in the ON position.
