Verify Read Range and Scan Width
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.
Scan width is that portion of the scan line in which a label can be read. For
ladder oriented labels, scan width must only be wide enough to fully cover
the label length, including quiet zones. With picket fence oriented labels,
scan width is a factor in determining the time in which the label can be read
(see Calculate Number of Scans” on page 1-4).

scanner bezel) in which the label can be reliably read. The distance between the minimum
