Scanning 2D Barcode
Adjust the scan angle and the distance between the MT65 and the target barcode to make them fall into the following
ranges:
1） Point the MT65’s focus lamp at the center of the barcode.
2） Move the MT65 until you find the appropriate scan distance.
3） Optimum scan angles:
Pitch (α)< 45° (0° preferably)
Skew (γ)< 45° (5°- 20° preferably)
Roll (β)= 0° - 360°
