A medium position determining device includes a sensor (50), and a scanning carriage (38) that is configured to move in a reciprocating manner in a scanning direction, in which the sensor is mounted to the scanning carriage. The device also includes a controller that is configured to move the scanning carriage and to determine a position of the scanning carriage with respect to the medium when the scanning carriage moves in the scanning direction. Moreover, the controller moves the scanning carriage at a first speed in the scanning direction, and after the controller determines that the scanning carriage is in a first position with respect to the medium, the controller moves the scanning carriage in the scanning direction at a second speed that is greater than the first speed.
