Troubleshooting
You can isolate problems with your scanning system by performing these checks (refer to Figure 9):
1.If your scanner’s cable is designed to receive Power Off the Terminal (P.O.T.), it will not operate unless it is connected to a working host terminal that is powered on.
2.Ensure that the interface cable is securely attached to the host. Consult your technical support manager or refer to your host system manual to identify the proper connection for the scanner.
3.If an external power supply is used, verify that it is securely connected to the interface cable and AC outlet. Also ensure that the power supply is the correct voltage rating for your area.
4.Check to see that the interface cable is securely connected at the scanner handle. Push the connector in to assure that it is firmly seated. Use a Phillips head screwdriver to ensure that the screw at the bottom of the scanner is fully tightened (but do not overtighten).
5.If, after checking all connections, the scanner still fails to function properly, exchange the power supply with a known good power supply.
6.Ensure that the scanner's interface type is compatible with the host terminal by consulting your POS system manual and/or the PowerScan Scanner Programming Guide.
7.Verify that the bar codes you are scanning are of satisfactory quality. Bar code label verifiers are available from your dealer if you need precise reporting of bar code details. Bar codes that are damaged (wrinkled, smudged, or torn) may cause the scanner to read poorly or not at all. If bar code quality seems to be the problem, check to see if the scanner will read a known good bar code (see Figure 7). You may also want to modify the programmable setting for advanced Quadralogic™ decoding (see the section in this manual titled, Enhanced Scanning for
