Appendix E
Scanning Tips
Practice to determine the best scanning angle and distance for
your type of bar code.
Aiming Beam
Aim the scanner so that the red beam covers the entire width of
the bar code.
Scan Angle — SD Scan Card 3M/3P
For best results with the laser-based SD Scan Card, position the
scanner at an angle to the bar code, at least 15° from
perpendicular. Otherwise, light can bounce back into the scanner
and “blind” the sensing mechanism.
