Datalogic Scanning QD 2300 manual Product Reference Guide, Aiming to Avoid the Dead Zone

Aiming

Do not hold the scanner perpendicular to the bar code when scanning. Laser light reflecting directly back into the scanner from the bar code can result in specular reflection, which can in turn cause difficulties with decoding. Tilt the scanner to avoid the dead zone (indicated by an ‘X’ in Figure 6) up to 65 degrees upwards or downwards.
