Overview
The online data validator (validator) is an external bar code
scanning device attached above the paper exit of the printer. When
activated, it scans the printed output looking for bar codes. When it
finds a bar code, it determines what type of bar code it is and
monitors the bar code quality as it passes through the scan area.
After the entire bar code has passed under the scanning beam, the
validator grades the bar code and sends a report to the printer. How
the printer responds is determined by the validator settings,
explained in “Configuring The Validator” on page 43.
Operational Parameters
The design parameters of the validator are as follows:
• The validator can track the performance of up to four horizontal
bar codes at one time.
• The validator requires a minimum distance of 1/2 inch or 20
times the minimum element width (x-dimension), whichever is
greater, between bar codes.
• The validator recognizes the following linear, picket fence bar
codes: Codabar, Code 39, Code 93, Code 128, Interleaved 2 of
5, and UPC/EAN + add-ons.
