Installation & Use |
USB
USB installation is described for a PC running Windows.
Other platforms and operating systems may differ and you should refer to your
computer documentation regarding the installation of USB devices.
The USB interface is specially designed to allow 'hot swapping'.
This means USB devices may be connected and disconnected while the computer
is switched on and running.
Very old versions of Windows before 2000 may not include USB support
even though some of these computers had USB connectors.
- Connect the scanner to a vacant USB connector.
Do not attempt to scan any barcodes until after the installation process is complete.
- After a second or two your PC will prompt for the driver disk. The USB drivers
needed for this scanner are part of the Windows operating system and are already located
in your Windows installation. Follow the on screen instructions.
- Installation of the USB driver need only be done once. However you may have to
install the driver on each USB socket if your computer has more than one.
The next time you fit the scanner a connection will be established automatically.
- Test the installation. Start a text editing program like Notepad. First make
sure your keyboard is working correctly. Now scan a barcode. The barcode data
should appear on the screen just as if they were typed from the keyboard.
Scanning normal barcodes
Barcode scanning is easy and intuitive. Simply point the
scanner at the barcode and press the trigger. Move the aiming beam
across the barcode. A beep will sound and the beam is switched off automatically.
If the scanner does not react immediately move it closer or further
from barcode. The exact distance between the scanner and barcode will vary
and is not critical. Typically it will be about 25-50mm (1-2 inches).
Make sure the aiming beam covers the entire
width of the barcode and is roughly parallel to it.
Scanning 2D barcodes
The scanning technique for two dimentional barcode like PDF417 is
slightly different.
Start with the aiming beam just outside and above the barcode symbol.
Slowly move the beam downward so it sweeps over the entire barcode symbol.
As you do so a 'scratching' sound will be heard. When the whole barcode
has been traversed a beep will sound and the beam is switched off automatically.
You may need a couple of attempts until the correct action
is learned. The following comments may help.
- The scanner should be held about 25-50mm (1-2 inches) from the barcode
such that the
aiming beam is just a little wider than the barcode symbol.
- The beam is moved across the whole barcode at a speed such that
the whole barcode is swept in about 1-2 seconds.
- You may find it easier to start at the bottom and sweep the barcode
with an upward motion. The sweeping direction doesn't matter. Use whichever
is easier for you.
- If the barcode does not read after the first sweep keep the trigger pressed
and sweep back again in the opposite direction. The scanner remembers earlier
sweeps and will 'fill in' on subsequent sweeps.
Maintenance
The scanner requires no regular maintence other than the occasional
cleaning of the scanning window with a soft damp tissue to remove
accumulated dust.
IMPORTANT: Never use a solvent on any part of the scanner.
