Abstract
A system that reduces pick skew and improves reliability of a picking mechanism by moving the pick arm to multiple locations across a media feed direction based on media size such that media pick forces are substantially balanced about the centerline of a media sheet to be picked. The system includes a pick arm slidably mounted on a shaft, at least one pick roller mounted to an end of the pick arm for contacting a top sheet of a stack of media sheets and driven to pick media sheets one at a time therefrom, and a pick arm translation mechanism for moving the pick arm along the shaft based on media sheet size of the media stack such that the at least one pick roller remains substantially evenly positioned about a centerline of a media sheet in a media feed direction.
