A media processing device includes: a hopper supporting media units (e.g. cards), and a biasing assembly biasing the cards toward a hopper outlet; an input roller for accepting a single card at a hopper slot inlet; a pick roller at the outlet for dispensing a card from the hopper to a media processing path; a motor having an output shaft; a primary drivetrain segment connecting the output shaft with the pick roller; an auxiliary output selector connected to the primary drivetrain segment and switchable between first and second output configurations; first and second auxiliary drivetrain segments connecting the output selector, respectively, with the input roller and a release member for disengaging the biasing assembly; and a selector input movable to switch the output selector between the first output configuration, coupling the primary and first auxiliary drivetrain segments, and the second output configuration, coupling the primary and second auxiliary drivetrain segments.
