2.3 Positioning The Scanner
Before installing the scanner, refer to the cautions given in Section 2.1.
The scanner must be installed so that the target plane is parallel to the scanner
window.
Refer to Fig. 3 (below). The width of the scan (
SW
) is proportional to the distance
(
TD
) between the scanner and the target plane. Choose a target distance that will give
a scan line that just exceeds the width of the product, as this gives maximum spatial
resolution.
