To return the rollers back into position, first place the left roller back, connecting to the white gear, and push down until you hear a click.

Make sure the larger black end is facing the small white connector rod for both rollers.

Align the ends of the white connector rod to the holes at the end of the right roller. Then place the right side of the right roller down first so you can connect the left roller to the white connector rod.

Push down between the white connector rod and the right roller until you hear a click.
