Abstract
A retractable scuffer includes an arm with foldaway drive wheels connected thereto that are independently pivotable to ensure even drive force on a sheet. The drive wheels flips down in a counter clockwise direction as the scuffer arm is driven to an extended position by a lead screw mechanism. This provides a shallow angle of contact with the sheet and allows the sheet to be pulled against a registration gate by the drive wheels versus being pushed, thereby eliminating unwanted reaction forces inherent in existing systems that push a sheet against a registration gate.
