Motorola MC9500-K - Decode Zones

Data Capture 4 - 3
Decode Zones
The decode zones for the laser scanners are shown in Figure 4-3 and Figure 4-4. The figures shown are typical
values. Table 4-2 lists the typical 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.
