The Scanner contains three cameras, each of which captures 1/3 of the full
width of the 36-in. (91.4 mm) scanner image. The view of the left and right
cameras must be adjusted to align with the view of the center camera. The
adjustment must be correct both for left to right alignment, and front to back
alignment.
