Aiming
Scan the Entire Symbol
• Cross every bar and space of the symbol with the scan beam.
• Hold the scanner further away for larger bar codes.
• Hold the scanner closer for symbols with bars that are close
together.
Right Wrong
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.”
