EC Min
NOTE: This parameter factors into the Overall Grade (page 66).
The higher the value, the stricter the criterion for passing.
This menu item sets the minimum edge contrast, which is the worst
edge transition (bar to space or space to bar) used by the validator
for pass/fail threshold during the analysis of bar codes. Bar codes
with an edge contrast below this threshold will fail.
You can set the EC Min parameter to a percentage value from 0%
to 100%. The default is 0%.
1. Press to take the printer offline and place the printer in
Menu mode.
2. If necessary, press ↓ and ↵
at the same time to unlock the
↵
key.
3. Press until VALIDATOR displays.
4. Press
↑ until EC Min displays.
5. Press + or – to scroll through the percentage values: 0% to
100%. The default is 0%.
6. Press
↵
to select the desired value.
7. Press ↓ and ↵
at the same time to lock the
↵
key, then press
PAUSE to take the printer offline.
8. Press PAUSE again to put the printer online.
Rmin
NOTE: This parameter factors into the Overall Grade (page 66).
This menu item sets the minimum reflectance value used by the
validator for pass/fail threshold used during the analysis of bar
codes. A bar code will fail if all the bar reflectance values are above
the percentage of space reflectance set by this threshold. For
example, an Rmin setting of 50% requires that at least one bar
reflectance value fall under the mid point of the reflectance value
read for the highest space reflectance.
You can set the Rmin parameter to a percentage value from 0% to
100%. The default is 100%.
