Patent attributes
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).
