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
•The validator recognizes the following linear, picket fence bar codes: Codabar, Code 39, Code 93, Code 128, Interleaved 2 of 5, and UPC/EAN +
