Abstract
A method for tracking the position of a sheet through a paper path being translated by a plurality of feed mechanisms within a printing machine is provided. The method includes the steps of driving a first feed mechanism with the motion of a first drive means, placing the sheet in cooperation with the first feed mechanism at a first position, translating the sheet with the first feed mechanism toward a second feed mechanism, driving the second feed mechanism with the motion of a second drive means, placing the sheet in cooperation with the second feed mechanism at a second position, translating the sheet with the second feed mechanism toward a the sheet output position, the paper path being defined by the motion of the sheet through the first feed mechanism and the second feed mechanism from the first position to the sheet output position and calculating the distance the sheet traverses while influenced by one of the first drive means and the second drive means based at least partially upon the motion of the other of at least one of the first drive means and the second drive means.
