Abstract
An apparatus for determining the height of a stack of sheet media in a supply bin is provided. The apparatus includes a sensor and a substantially linearly extending member. The member is operatively associated with the optical sensor to permit relative motion between the sensor and the member. At least one of the sensor and the member moves with the supply bin. The sensor generates a signal indicative of the relative motion between the sensor and the member. The relative motion provides an indication of the height of the stack of the sheet media.
