The printed bar codes are
causing error conditions.
(continued)
If your application is not acting reliably, there are other possible factors including the reflectivity of the media and/or
ambient light affecting the camera's ability to capture an image. Users should decrease the print speed in these situations
to see if this improves performance.
Table 5. Troubleshooting the Validator
Symptom Solution
•
Bar code type. The validator only recognizes
the following linear, picket fence bar codes:
Codabar, Code 39, Code 93, Code 128,
Interleaved 2 of 5, and UPC/EAN, PDF417
and Data Matrix.
•
Bar code spacing. The validator requires a
minimum distance of 1/2 inch or 20 times the
minimum element width, whichever is greater,
between bar codes.
Printer speed. See "
• Print Speed Limits" on page 22. If problems
persist, decrease the Media > Speed > Print
Speed.
•
Be sure the bar code is not printing on the
extreme edges of the label.
Clean the printhead. See "Cleaning" in the
•
Administrator's Manual.
•
Check that paper and ribbon are clean,
unwrinkled, and installed correctly.
•
Check the number of bar codes being
validated concurrently. The validator can track
the performance of up to 50 barcodes at one
time.
