Figure 2-1. Holding the Scanner
Aiming the Scanner
Hold the scanner 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.
