Symptom
The printed bar codes are
causing error conditions.
Table 5. Troubleshooting the Validator
There are several factors which could be causing
validation errors:
•
The ODV2D-V2 is not properly aligned with
the printer. See "Calibration" on page 22.
•
The ODV2D-V2 White Gain / Reflectance may
need to be calibrated. Complete White Gain
calibration on page 29 and Reflectance on
page 32.
•
Make sure the entire bar code passes
completely under the scanning beam.
•
The validator and printer are not properly
communicating. Test the validator operation
without using a host. See 2D Validation Demo
page on page 33.
•
Bar code width. The validator can recognize
x-dimensions as narrow as 10 mils.
•
Bar code size. A minimum height of 0.10 inch
is required for validation. If problems persist,
increase the bar code height.
