Narrow Margins
Note: Do not use Narrow Margins with Large Intercharacter Gap Enabled with Code 39.
Symbology Identifier
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. When Narrow Margins is set to Enabled, the
imager uses a 5x margin requirement for standard linear symbols.
Serial Cmd: <K450,narrow margins,symbology identifier status>
Default: Disabled
Options: 0 = Disabled 1 = Enabled
Definition: Symbology ID is an ISO/IEC 16022 standard prefix set of characters that
identifies the symbol type.

(closed bracket character) indicating the presence of a symbology identifier.
• A = Code 39
C = Code 128
E = UPC/EAN
F = Codabar
G = Code 93
