Using the Laser Scanner
The LaserTraq’s laser barcode scanner is designed to be easy to use. If
you’re at a stage in the application program where scans can be made,
just press the oval shaped orange button under the display to activate the
laser. The intense red beam is called the “scan line”, and all you need to
do is to position this scan line across the barcode to be read as indicated
below.
Once the scanner has read the barcode you’ll hear a “beep” to signal a
good read, and the barcode contents will be displayed on the screen of
your LaserTraq (unless the program handles scans otherwise).
When you’re positioning the scan line,
you must ensure the scan line covers
all
the bars and is at right angles to the
bars, as shown on the right.
Remember, a successful scan is
indicated by a “beep”. If you don’t hear a beep then try to scan the
barcode again, and check that your LaserTraq application program is
supposed to read the type of barcode label that you are trying to read.
The examples below should help you understand the acceptable ways to
position the laser beam scan line.
