ABSTRACT:
A sheet feeding mechanism including a pick apparatus for selectively moving a sheet of media from a stack. The invention is a counter rotating roll design that uses staggered and nested rolls to achieve separation. The invention includes a separator roll mounted on a first shaft between first and second `D` shaped pick tires mounted on a second shaft. A kicker is mounted on the first shaft along with the separation roll. The kicker flexes as it engages the stack when the shaft is rotated and, after it has rotated around, pushes media remaining on the separation roll back onto the stack.
