the screw behind it.
Reinstallation tip If the product is installed on the optional paper feeder, you must slightly
separate the product and the feeder assembly to install this connector. Open the right door on the
feeder. Use the blue handle to release the product-accessory lock, and then lift up on the edge of
the product to create a slight gap between the product and the accessory.
