Introduction
About the Scanner
The QuickScan Lite 2D QW2400 area imager is an entry level product specifi-
cally designed for reading long and truncated 1D codes and larger 2D codes
from close distance. The QW2400 imager has an extra-wide Field of View which
captures these challenging 1D and 2D codes at a nominal distance using differ
-
ent scan angles, meeting the scanning needs in Retail, Light Manufacturing,
Document/Bill Processing and Banking/Finance. The QuickScan Lite 2D imager
is the most affordable area imager with the best performance in its class.
Using the QuickScan Reader
QuickScan readers automatically scan barcodes at a distance. Simply aim and
pull the trigger. Code scanning is performed along the center of the light
square beam emitted from the reading window. This square beam must cover
the entire code.
Effective scanning is obtained by tilting the scanner with respect to the barcode
to avoid direct reflections, which impair the reading performance (see Figure 1A
below). A successful read is signaled by an audible tone, plus a good-read
green spot. The upper illuminator becomes green.
In order to operate the reader using the stand, first read the label on the base
of the stand and then insert the reader into the stand. The reader is now ready
to automatically read any code present in its reading area without pressing the
trigger. Furthermore, a blue spot is continuously emitted to facilitate the aim
-
ing of the bar code to be read (shown in Figure 1B).
To guarantee single code reading, consecutive reading of the same code
requires the code to be removed from the reading area (no decoding) before
the reader will accept the same code again.
