Remove 2 screws to remove the metal bar from the fuser.

After removing one screw, this small circuit board can be removed.

The board contains a beam interrupt sensor, which contains an infrared LED pointing at an infrared phototransistor. When an object enters the slot and breaks the beam, the phototransistor detects it as a drop in infrared light.
