Usable Scan Length
The decode zone is a function of various symbol characteristics including density, print
contrast, wide-to-narrow ratio, and edge accuracy. Consider the width of the scan line at
any given distance when designing a system.
Calculating The Usable Scan Length Method on page 2-14 describes how to calculate the
usable scan length. The scan angle is provided in Table 4-3 on page 4-5.
