Abstract
An apparatus in which the approximate thickness of a set of sheets is determined. A tray supporting a stack of sheets thereon is periodically indexed a preselected distance each time the thickness of the stack of sheets decreases by a specified amount. The approximate thickness of the set of sheets is calculated as a function of the number of times the tray is indexed and a constant corresponding to the preselected distance the tray indexes.
