Q u i c k
Aiming
Hold at an angle
Do not hold the scanner directly over the bar code. Laser light
reflecting directly back into the scanner from the bar code is known
as specular reflection. This strong light can "blind" the scanner and
make decoding difficult. The area where specular reflection occurs
is known as a "dead zone".
You can tilt the scanner up to 55° forward or back and achieve a
successful decode. Simple practice quickly shows what tolerances to
work within.
Scan the Entire Symbol
•
The scan beam must cross every bar and space on the symbol
(as in the left bar code below).
•
The larger the symbol, the farther away you should hold the
scanner.
•
Hold the scanner closer for symbols with bars that are close
together.
