Scanning Considerations
Typically, scanning is a simple matter of aim, scan, and decode where a few quick trial efforts master it. However,
consider the following to optimize scanning performance:
• Range
• Any scanning device decodes well over a particular working range — minimum and maximum
distances from the barcode. This range varies according to barcode density and scanning device
optics.
Scanning within range brings quick and constant decodes; scanning too close or too far away prevents
decodes. Move the scanner closer and farther away to find the right working range for the barcodes
being scanned.
• Angle
• Scan angle is important for promoting quick decodes. When laser beams reflect directly back into the
scanner from the barcode, this specular reflection can “blind” the scanner.
To avoid this, scan the barcode so that the beam does not bounce directly back. But do not 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 device farther away for larger symbols.
• Move the device closer for symbols with bars that are close together.
