Chapter 2 Bar Code Failures
64
The printer will stop, indicate an error, and overstrike as described
above. Then it will skip a number of blank labels, depending on the
setting for Skip Labels (see “Setting For Skip Labels”on page 51).
It will then slew to the next top of a blank form and reprint the entire
formt hat contained the bad bar code and any other forms that were
perhaps interrupted by the error.
NOTE: Because of physical differences between the location of the
print head and the scanning beam, it is likely that a second
form will be started before the first form has finished being
assessed. Therefore, the reprint operation will need to
reprint more than just the form with the error.
If the printer has to reprint the same form five times in a row, the
print job stops completely and behaves the same as in Stop mode.
Error Messages
The validator can detect a number of errors. When one of these
errorso ccurs, the validator alerts the printer to perform the currently
selected error action (see “Error Action”on page 62) and show the
appropriate error message on the printer display. Validator erro r
messages are explained in Table 4.

Message Explanation Solution
Bar Code Improper
Data Format
Data validation error: the bar
code is not properly encoded.
For example,a check sum is
incorrect, a required number
of characters is not met, or
the required terminator
characters are not included.
Thisproblem is almost
alwayscaused by incorrect
form or host application
design.
Fix the application so it
sends data in the correct
bar code format.
