ABSTRACT:
This invention relates to a picker assembly for a printer having rollers to feed a sheet of porous print media past a printhead. The picker assembly includes a pivot rod linked to a pick-up bar by means of swing arms, a motor connected to the pivot rod operatively reciprocated between a stack of sheets and the rollers. The assembly also includes a number of fluid ports located on the pick-up bar, said ports having pads to facilitate contact with the print media, and a pump configured to deliver air to and extract air from the fluid ports via a fluid delivery manifold and a fluid extraction manifold, respectively. Further included is a valve arrangement alternately connecting the delivery manifold and extraction manifold to the pump in time with the reciprocating motion of the pivot rod, so that the sheet is lifted from the stack and fed between the rollers each time the pivot bar is reciprocated from the stack to the rollers.
