Abstract
A sheet media handling apparatus includes an air plenum having a first set of openings for passing air in the vicinity of a sheet media being handled and a second opening; and a fan including a flat brushless DC motor mounted adjacent the second opening and a centrifugal impeller attached to the motor and positioned so as to move air through the second opening when rotated by the motor. A pressure sensor connected to the motor drive circuit controls the speed of the motor in an inverse relationship to atmospheric pressure so that sufficient air pressure is provided for the sheet handling apparatus while minimizing the noise generated by the apparatus.
