In order to be able to supply a rotating transfer roller in a transfer printing station of an electrophotographic printing device with a high voltage, a system and method is proposed that comprises a voltage transfer device with an elastically borne brush, a compensation device with a bushing standing under spring force, and a monitoring device with a Hall switch. For voltage transfer, the brush is pressed onto the voltage connection location of the transfer roller. For compensation of the axial play of the transfer roller, the bushing is pressed onto the bearing of the transfer roller. For monitoring as to whether a transfer roller is connected with the device, the Hall switch is used which checks whether the bushing has been moved or not.
