There is a setting on one of the switches on the document camera that can cause the image to project with a black border at the top and the bottom of the screen.
Look at the side of your doc cam and you'll see two black switches. If the leftmost switch is set to the left position, push it to the middle or right position. The top and bottom borders on the projected image should disappear.
