Appendix D (Quiet Zone Analysis)

Quiet Zone Analysis

The RJS Inspector D4000 trims data gathered during a

scan to approximately 10 times the X dimension on

each side of a bar code for all symbologies except

UPC and EAN. The areas are assumed to be quiet

zones and are included in the symbol analysis. If a low

reflectance object is detected in these areas the

screen displays:

Std I2of5

described in the following tables. In cases where an
