A media transport element comprises: a fixed roller, a first coupling connected an end of the fixed roller for receiving rotational motion therefrom, a second coupling connected to the first coupling for receiving rotational motion therefrom, and being rotatable about a pivot axis; and a pivoting roller mounted in registration with the fixed roller. The fixed roller and the pivoting roller define a media passage therebetween. The media transport element also comprises: a link coupled to the pivoting roller and mounted on a link shaft co-axial with the pivot axis. The fixed roller and the pivoting roller are both continuously driven even when media items pass through the media passage and move the pivoting roller away from the fixed roller.
