Active pre-registration system using long sheet transports

Cross reference is hereby made to co-pending U.S. application Ser. No. 09/739,955 by Alan G. Schlageter which application is commonly assigned and entitled "Active Pre-Registration System Employing A Paper Supply Elevator". A pre-registration system increases the latitude of present active registration systems by decreasing the lateral offset of sheets before they reach the active registration system. This is accomplished by pivoting a long transport with a stepper motor in conjunction with sensing a lateral edge of the sheets in order to direct the sheets to the proper lateral position to be fed into the active registration system with a minimum of lateral offset.
