Changing Character Spacing Threshold Values
The decoder identifies wide character spacing as an anomalous pattern, which may result in the
inability to scan. Disabling the character spacing determination function overcomes this problem.
Depending on the barcode system, some codes may have character spacing while others may not.
This change is effective for those codes which have character spacing. The symbologies on which
this change is effective are listed below.
-
Code39
-
NW7
-
Industrial 2of5

IATA
While Industrial 2of5 and IATA symbologies do not have character spacing, it is possible to
enable or disable the check which is carried out to determine the ratio of the white bars located
between the black bars.
Changing Guard Bar and Delineator Threshold Values
When scanning EAN, JAN, UPC-A, and UPC-E symbologies, it may not be possible to scan due
to irregular guard bar ratios. Similarly, when reading Add-on symbology, it may not be possible to
scan due to irregular delineator ratios. This problem can be overcome by disabling the guard bar
and delineator check functions.
The guard bar element is only present in EAN, JAN, UPC-A, and UPC-E symbologies while the
delineator element is only present in Add-on symbology. This change is effective on the following
symbologies.
-
EAN, JAN, UPC-A, UPC-B
-
EAN, JAN, UPC-A, UPC-B Add-ons
-
UPC-E
-
UPC-E Add-on
Changing Thick Bar Determination Threshold Values
Scanning may be hampered by misidentification of the bar pattern which occurs when only the
thick or thin bars are printed or when the gap between the thick and thin bars is slight. This
problem can be eliminated by changing the threshold values for determining thick bars. This
change is effective on the following symbologies.
