Range
Any scanning device decodes well over a particular working range — minimum and
maximum distances from the bar code. This range varies according to bar code density and
scanning device optics.
Scanning within range brings quick and constant decodes; scanning too close or too far away
prevents decodes. You need to find the right working range for the bar codes you are
scanning. The best general advice is:
!
Hold the scanner farther away for larger symbols.
!
Hold the scanner closer for symbols with bars that are close together.
!
Start scanning at a distance from the bar code, not from direct contact. If the bar
code does not readily decode, move the scanner in closer.
!
Practice quickly shows what distances to work within.
