20080296835 | MOVING CARRIAGE LATERAL REGISTRATION SYSTEM - A method of registering sheets laterally and in skew enables active sheet deskew without translating the sheet in the cross-process direction. A sensor carriage position is controlled to find the sheet edge after which deskew control can start. The average value of the carriage position can then be fed in a feedforward manner to move the image location to match the average paper position. This achieves good average lateral registration and active skew control at a reduced cost. | 12-04-2008 |
