Solution/Explanation
The printer received the complete program but the
checksum did not match. The data may have been
corrupted during download.
1. Power off the printer for 15 seconds, then power back
on.
2. If the problem persists, contact your authorized
customer service representative.
The validator detected that the barcode fails checksum or
is missing the checksum digit.
Verify that the checksum digit exists in the barcode and that
it is the correct value.
Data validation error: the contrast between bars and
spaces is not sufficient. This can be caused by too little
heat in the thermal transfer or by use of colored media or
ribbons.
1. Increase Media > Image > Print Intensity or reduce
Media > Speed > Print Speed in the menu or via
host software.
2. Change media (another option).
3. Set Symbol Contrast = 0% (to disable it) in the
VALIDATOR menu.
