Patent ID: 8317191

Claim:
An apparatus comprising: a media path comprising moving devices that move a media sheet in a processing direction; two elongated sensors within said media path positioned diagonally relative to said processing direction, said media sheet comprising two lateral sides, a leading edge, and a trailing edge; and a registration controller operatively connected to said media path and to said two elongated sensors, each of said two elongated sensors simultaneously identifying: a location of one of said lateral sides of said media sheet, such that a combination of said two elongated sensors simultaneously outputs two lateral measures of locations of said lateral sides of said media sheet; and at least one measure of said leading edge or at least one measure of said trailing edge of said media sheet, such that said combination of said two elongated sensors simultaneously outputs at least one leading edge measure of a position of said leading edge of said media sheet or at least one trailing edge measure of a position of said trailing edge of said media sheet, and said registration controller utilizing said two lateral measures and said at least one leading edge measure or said at least one trailing edge measure to determine a skew and a position of said media sheet, and said registration controller calculating a registration correction factor based upon said skew and altering actions of said moving devices based on said correction factor to correct said skew.
