MS-804FZY Decode Zone
The decode zone for the MS-804FZY scanner is shown in Figure 3-3 . The figures shown
are typical values. Table 3-3 lists the typical and guaranteed distances for selected bar code
densities. The minimum element width (or “symbol density”) is the width in mils of the
narrowest element (bar or space) in the symbol. To calculate this distance, see
Calculating
The Usable Scan Length Method on page 2-10.
