A sheet transfer apparatus includes a first roller, a second roller and a power train. The first roller is configured to be rotatably driven at a first surface speed. The second roller is spaced from the first roller such that the first roller and the second roller are configured to simultaneously engage a media sheet. The second roller is configured to be driven at a second surface speed greater than the first surface speed. The power train delivers power to the first roller to rotatably drive the first roller. The power train includes a first gear coupled to the first roller, a second gear and a third gear. The third gear is movable between a first position in which the third gear is in power transmitting engagement with both the first gear and the second gear and a second position in which the third gear is out of power transmitting engagement with the second gear.
