Claim 8:
9. A method, comprising
providing a receiving roller to receive a print medium and an electric motor to rotate the receiving roller;
applying a bias voltage to the electric motor, wherein the bias voltage is below a threshold voltage, wherein the electric motor is to set in motion when powered at least by the threshold voltage;
detecting rotation of the receiving roller caused by an external force;
in response to detecting the rotation of the receiving roller, applying a driving voltage to the electric motor to generate an assisting force to further rotate the receiving roller;
determining a current rotational speed of the receiving roller; and
controlling the driving voltage according to a predefined function of the current rotational speed of the receiving roller.
