ABSTRACT:
A method for aligning print media on a feedpath includes the steps of: aligning a sheet of print media using a deskew mechanism; measuring the skew of the sheet after it has been aligned; and comparing the measured skew with a specified skew, and if the measured value is greater than the specified value, reversing the sheet through the deskew mechanism followed by repeating the aligning, measuring and comparing steps. An apparatus for implementing alignment of print media on a feedpath comprises a deskew mechanism and sensors positioned downstream on the feedpath from the deskew mechanism to provide data sufficient to calculate the skew of the sheet.
