3–2 Installation Considerations
Bar code symbols must be in the correct orientation as they move by
the scanner. The scan line must cross every bar, space and quiet
zone on the symbol in one sweep.
The orientation of the bar code symbol can be picket fence or step
ladder. The orientation is determined by the symbol’s direction of
travel relative to the scan line, not the horizontal or vertical
orientation of the symbol.
