Paxar 9403, 9402 manual Dark, Spec

Select the print speed based on desired throughput and print quality. If print quality is more important, reduce the print speed, because a lower print speed increases the print quality of labels. If throughput is more important, increase the print speed as high as it will go to give you the needed print performance. See "Increasing Throughput" for more information.

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.

Dark IN SPEC Light

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.
