8. Aiming

During a scan, the green LED patterns shown below will be visible. These patterns assist

you in aiming the scanner; they are superimposed on the illuminated scan field. The

aiming patterns are only a guide. They do not indicate exact scannable width or distance

between a scanner and a barcode.

•

The focal point is where two central LED light patterns (green and square-shaped)

overlap—where two dots meet.

•

To scan a barcode within the aiming range, make sure that two central LED light

patterns overlap, then place the center of the overlapping LED light patterns on the

center of the barcode.

•

To scan a barcode wider than a width of the aiming range, aim at the barcode from

further away. Make sure that the barcode is between two LED light patterns on both

the right and left.

•

Scanning performance may decline due to the specular reflection when the

symbology is printed on certain types of materials. In such cases, incline the scanner

at 15 degrees to adjust the scanning angle.
