Abstract (en)

[origin: EP2127874A1] The method involves arranging a clutch (21) between a motor (11) and a roller (6), and controlling the motor by a control device (37) such that another roller (5) is rotated at a rotational speed, which is in constant relation with a rotational speed of the former roller. The rollers are rotatively driven by the motor in an operating mode i.e. maintenance mode, for transferring torque from the motor to the former roller over the clutch. Current of the motor is periodically increased in a print operating mode by the control device.
