Classification: CPC B  H  G | IPC B

Claim 9:
10. A device, comprising
a receiving device to receive a print medium;
an actuator to apply an assisting force to the receiving device when a driving voltage is applied to the actuator; and
a control unit to control the actuator, detect rotation of the receiving device, and determine a current rotational speed of the actuator;
wherein the control unit is to operate the actuator in response to detecting the rotation of the receiving device caused by an external force, and
wherein the driving voltage is a function of the current rotational speed of the actuator, the function differing from a characteristic function of the actuator and the characteristic function defining a rotational speed as a function of applied voltage.
