Patent ID: 7963519

Claim:
A media pick system for a printing device, comprising: a rotatable pick arm, having a pick roller and a pre-pick roller attached thereto; a biasing member, attached to the pick arm, configured to bias the pick arm toward an engaged position of the pre-pick roller with a stack of print media with a biasing force of the biasing member to the pick arm that only increases as a deflection angle of the pick arm increases; and a drive system, configured to selectively (1) cause the pick arm to rotate in a first direction to the engaged position, and (2) rotate the pick arm in a second direction against the force of the biasing member to a disengaged position, wherein the drive system comprises: a drive shaft, associated with the pick roller, configured to provide driving power to the media pick system; a pre-pick roller drive train, interconnecting the pick roller and the pre-pick roller; and a planet gear, engaged with the pick roller, selectively moveable between a position of engagement with the pre-pick roller drive train, and a position of disengagement from the pre-pick roller drive train.
