Abstract
A device for pre-picking a top sheet of media from a stack is disclosed. A biased friction pad is mounted on a D-shaped pick roller mechanism to engage the top sheet with a lighter force than that which follows when a similar friction pad on the D-shaped pick roller mechanism engages the sheet. Multiple sheet pick problems inherent with use of only a D-shaped pick roller mechanism are alleviated.
