Linear Scanning - Symbol MC70 User Manual

2 - 22 MC70 User Guide
• Angle
Scanning angle is important for promoting quick decodes. When laser beams reflect directly back into the
scanner from the bar code, this specular reflection can "blind" the scanner.
To avoid this, scan the bar code so that the beam does not bounce directly back. But don't scan at too
sharp an angle; the scanner needs to collect scattered reflections from the scan to make a successful
decode. Practice quickly shows what tolerances to work within.
Hold the EDA farther away for larger symbols.

• Move the EDA closer for symbols with bars that are close together.
Scanning procedures depend on the application and EDA configuration. An application may
