Table 7. Troubleshooting the Validator
Symptom
The printed labels look clean, but
the validator is still reporting an
error message.
The printed bar codes are
causing error conditions.
Solution
The validator glass may be dirty, distorting the
report results. Power down the printer and clean
the glass using a household glass cleaner and a
dry, lint-free cloth.
There are a number of factors which could be
causing validation errors:
The scanning beam is not properly aligned
•
with the two notches on the tear bar of the
printer. See "Adjust The Scanning Beam" on
page 27.
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 "Bar Code
Validation Demo Page" on page 36.
•
Bar code width. The validator can recognize
x-dimensions as narrow as 6.6 mil for
300 dpi printers, and 10 mil for 203 dpi
printers. The validator cannot recognize
x-dimensions smaller than 6.6 mil or larger
than 40 mil.
Bar code size. A minimum height of 1/8 inch
•
is required for validation. If problems persist,
increase the bar code height.
•
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. Stacked, 2D, and vertical
(ladder) bar codes are not supported.
