Abstract
A method of measuring a thickness of a sheet being conveyed on a transport path includes rotating a substantially cylindrical reference surface disposed in the transport path and engaging a probe with the reference surface to determine a runout value for each of a set of positions along a circumference of the reference surface. The method further includes conveying the sheet on the transport path so that the sheet contacts the reference surface at one position of the set, engaging the probe with the sheet at the one position to determine a measured sheet thickness value, and adjusting the measured sheet thickness value based on the runout value for the one position to obtain an actual sheet thickness value.
