Abstract:
A method for aligning print media on a feedpath, comprising:(a) aligning a sheet of said print media using a deskew mechanism; (b) measuring the skew of said sheet as it is fed out of said deskew mechanism, said measuring being implemented by a plurality of sensors positioned on said feedpath to detect a leading edge of said sheet as it emerges from said deskew mechanism, said sensors being spaced apart along an axis which is substantially perpendicular to a direction of movement of said sheet along said feedpath, such that said leading edge is detected by at least two of said plurality of sensors; (c) comparing said measured skew with a specified skew, and if said measured skew is greater than said specified skew, reversing said sheet through said deskew mechanism and repeating steps (a) through (c); and (d) detecting a trailing edge of said sheet and calculating the length of said sheet on the basis of said detecting.
