Message
Data validation error: the
blank zone(s) left or right of
the bar code is not big enough
to meet the minimum
requirement.
Typically, this occurs in forms
where bar codes are placed
too close to other elements,
the bar code is too close to an
edge of the media, or the
media's position is shifting.
The minimum quiet zone on
each end of the bar code
should be ten times the
minimum element width or
1/4 inch, whichever is greater.
In addition, between bar
codes, the validator requires a
minimum distance of 20 times
the minimum element width or
1/2 inch, whichever is greater.
The validator has detected
that it needs calibration. This
message is a reminder and
does not halt printing.
The bar code data fails the
checksum check or is missing
the checksum digit.
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.
Communication error
between printer and online
data validator (ODV).
