Scanning range and field of view

Scanning range and field of view
  1. Scanner specifications are values obtained under an ambient light intensity of 500 lx or lower.
  2. Depending on light source position, angle to the label surface, and other factors, specular reflections may prevent scanning in certain cases.
  3. Close-distance scanning may be restricted in certain cases, depending on scanning field of view.
