Instruction manual

¨ If the print quality is too light or too dark, adjust the print contrast. The
correct contrast setting is important because it effects how well your bar
codes scan and how long the printhead lasts.
Be sure to check the print quality of bar codes with a bar code verifier or
scanner. If you do not have a verifier or scanner, check the bar code
visually. A bar code that is IN SPEC will have complete bars and clear
spaces. Small alphanumeric characters will look complete. A bar code
that is IN SPEC may not look as good as one that is too dark, but it will
have the highest scan rate.
Note: For highest scan rates, make sure there is adequate white space
before and after the bar code. Also, a darker bar code does not
mean it will scan better.
The following non-print zones are recommended:
All Supplies .050 inches on either edge of the label.
All Supplies .020 inches at the end of the label.
If using the optional verifier, allow a minimum no-scan zone on the trailing
edge of the label of 0.5 inches (13 mm).
