Narrow Margins
Note:
Do not use
Narrow Margins
when
Large Intercharacter Gap
is enabled for Code 39.
Enabled
When Narrow Margins is set to Enabled, the imager uses a 5x margin requirement for
standard linear symbols.
2D Enhanced
2D Enhanced enables a special decode algorithm for narrow-margin 2D symbols.
Usage: Used when the leading and trailing edges of the symbols are smaller than
the standard margin or other objects encroach into the margins.
Definition: Allows the imager to read 1D symbols with quiet zones less than 8 times
the width of the narrow bar element. “Quiet zone” is the space at the leading
and trailing ends of a symbol. Each quiet zone can be as narrow as only
five times the width of the narrow bar element when Narrow Margins is
enabled.
