Verify Read Range
Table 1-1 shows readable ranges and maximum scan widths for specific
bar code density (narrow-bar-width) types. Use this table as a reference to
verify that the planned range for your label falls within one of the listed
ranges.

.030" 4" to 20" (10.2 to 50.8 cm)
.040" 4" to 20" (10.2 to 50.8 cm)
.005" 2" to 4.25" (5.1 to 10.8 cm)
.0075" 2" to 5" (5.1 to 12.7 cm)
a. Read range is the distance of the label from the scanner (measured from the front of the scanner
bezel) in which the label can be reliably read. The distance between the minimum and maximum
ranges is the depth of field.
b. FIS (Final Instruction Sheet) option.
Note: Optimum read rates can be expected at the center of the depth of field (half-
way between minimum and maximum read range) for a given bar code density.
