On the bottom of the scanner, remove the screw at the top left side.

Remove the rubber foot pad opposite the screw hole to expose a second screw hole.

Remove the screw beneath the foot-pad.

Rotate the scanner so the screw hole is located on the top left hand side.

Place the plastic opening tool between the top casement and bottom casement of scanner with the hook facing up.

Gently pry the two casements apart beginning above the screw hole and working your way around.

Separate the two casement pieces.

Remove the screw holding the tension spring in place.

Use the plastic opening tool to lift up the tension spring.

Remove the belt from the spool.

Loosen the belt enough to turn over the sensor bar.

With the sensor bar turned upside down, remove the screw in the middle of the bar.

Lift off the metal plate if it does not come away with the screw.

Carefully lift the belt out of the groove in the sensor bar to remove.
