An apparatus for recording an image onto a sheet medium ( 12 ) has an entrance drive roller ( 16 ) paired with a corresponding entrance pressure roller ( 18 ) to form an entrance nip ( 14 ) for transporting the sheet medium into an image recording section ( 20 ). The image recording section has a write head ( 56 ) for recording onto a portion of the sheet medium being transported between the entrance nip ( 14 ) and exit nip ( 24 ). The exit nip is formed by a drive roller ( 26 ) paired with a corresponding exit pressure roller ( 28 ) for transporting the sheet medium out from the image recording section. A motor ( 60 ) provides rotary motion to a pinion roller ( 40 ) mechanically coupled to the entrance and exit drive rollers ( 16, 26 ). A loading mechanism provides a loading force to nest the pinion roller into rotational contact against a portion of the entrance and exit drive rollers ( 16, 26 ).
