(54)	A capacity control system for a paper supply elevator

(57) A capacity control system for a paper supply elevator comprises a paper support (16) and a paper sensor (52) for detecting the presence of paper on the paper support. A home position sensor (14) detects a home position of the paper support. A stack up sensor (36) detects a topmost sheet of paper in a stack of papers located on the paper support (16). An intermittent drive (22) raises and lowering the paper support (16). A control panel (32) inputs an expected paper stack size. A control circuit for the intermittent drive (22) causes the intermittent drive to move the paper support (16) to a position corresponding to the expected paper stack size.
