Wasp Bar Code WPS100 manual Aiming, Maximum Tilt Angles and Dead Zone

Wasp WPS100 Product Reference Guide

Aiming

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 specular reflection can make decoding difficult.

You can tilt the scanner up to 45° forward or back and achieve a successful decode (Figure 2-9). Simple practice quickly shows what tolerances to work within.
