Basic Validator Setup
Unit Positioning
The validator must be positioned so that the scanning beam covers the entire area containing the bar codes, including the area required for quiet zones. The validator can be moved along the lower bracket and aligned with any of the inscribed hash marks, depending on the size of the labels printed and the positioning of the bar codes on those labels. In addition, the beam width can be moved horizontally to the left or right. See “Summary Of Scanning Beam Adjustment” on page 32.
If a bar code is completely outside of the scanning area, straddles an edge, or does not pass completely under the scanning beam, the validator interprets it as a missing bar code and generates error conditions.
Validator Front Panel
The front panel of the validator has the following controls and indicators:
•POWER: Indicates the validator is at full power.
•CALIBRATION: Flashes when the validator is in calibration mode. See page 34 for calibration instructions.
•READ: Flashes when the validator is reading a bar code.
•1 and 2: Used for maintenance purposes only.
