Abstract
A registration assist device is provided which presses a sheet located in the slot of a disk against a surface of the disk for a time period which begins prior to and extends until just after the time when a leading edge of the sheet contacts a registration wall which strips the sheet from the disk slot. This pressing of the sheet causes a drag force to be applied to the sheet so that the leading edge of the sheet is re-registered with the registration wall to compensate for any bouncing of the sheet away from the registration wall after initial contact therewith. Preferably a foam roller is moved into and out of a curved plane defined by the disk slot in timed relation to the rotation of the disk to press the sheet against the slot surface. The use of a foam roller provides a variable force to the sheets depending on the weight of each sheet so that higher drag and pressing forces are applied to heavier weight sheets which require and are able to withstand higher forces.
