Abstract
A system and method for providing the ability to more effectively control a paper stack in a reproduction apparatus. The level control behavior of the paper stack is characterized, and accordingly, additional lift commands are signaled when the behavior indicates that such increments are necessary. The behavior is characterized by sampling data during a sampling period including switch initiated increments. Upon characterization, additional increments are initiated by a source other than the switch initiated increments to more effectively control the paper stack.
