Patent ID: 8083228

Claim:
A printmaking device for performing closed loop lateral and skew control of a sheet using a single lateral sensor in a sheet registration system comprising: a feed path adapted to move the sheet, the sheet including a first edge and a second edge, a first side edge and a second side edge, the first side edge and the second side edge each extending between the first edge and the second edge, wherein said first edge is approximately parallel to said second edge; a printing module configured to print an image on the sheet; and a sheet registration system along said feed path including a lateral sensor being configured to measure a lateral position of said first side edge of the sheet at a fixed reference along said feed path to determine a lateral position error of said first side edge; a registration controller operatively connected to said lateral sensor, the registration controller being configured to calculate an angular velocity to be applied to the sheet that is sufficient to correct the lateral position error in the sheet by reference to the lateral sensor alone; and at least one pair of registration nips along said feed path and operatively connected to said registration controller, said at least one pair of registration nips configured to apply said angular velocity to the sheet.
