Abstract
A hardcopy device has various page processing steps in a printer, fax machine or the like which are actuated by a single motor which connects through a gear mechanism to drive a main drive roller, a pick roller, and automatically move a pressure plate in a feeder slot to and fro between a position of engagement holding a stack of pages against the pick roller and a position of disengagement. A reverse action of the pick roller kicks out partially picked pages into the feeder slot after the pressure plate is moved to a position of disengagement.
