A method for the measurement or testing of the degree of corrugation induced in paper sheets, such as that induced between a pair of sheet feeding nips in a copier or printer. This measurement allows the quantifying of improvements or adjustments for manufacturing or the like. In particular, overcoming problems caused by corrugations induced in paper path nips sets by "steering" in between a pair of nips trapping the corrugation, similar to the action of cross rolls. This can create a paper buckle which can cause the sheet to jam in the subsequent baffles or gates.
