one end, which is to help you place the chip correctly in the socket on the
board. The socket has the same notch as well.

• Slowly lift up the cover plate on its near side and gently turn it back over.
• Lift the right end of the cover plate. Find the loose end of the ribbon cable

connector around and try it the other way.
• Place the cover plate back down on the scanner. To lock it into place, slide
the cover plate to the left. Then replace the cover screws.
