5.9 Troubleshooting

For problem detection and troubleshooting, examine your scanner as follows:
1. If the scanner is supplied with power via the connection cable, the scanner and PC must be connected to
each other before the scanner is commissioned. The PC must supply the scanner with 5 V DC. Check the
manual for your PC to ensure that the power supply is adequate for connecting your scanner.
2. Make certain that the connection cable is securely connected to the PC. You can find information on
properly connecting the scanner in the manual for your PC. Support is also available from your technical
staff.
3. If your system operates with an external voltage supply, make certain that the power supply unit is
properly connected to the scanner.
4. Check that the connection cable is securely connected to the base station. At the base station, please
loosen the cable using a small pin: the connector is unlocked.
5. If, even after performing all of these measures, the scanner is not ready for operation, replace the power
supply unit with a different recommended power supply unit which you are certain functions properly.
6. Make certain that your scanner's interface is compatible with the PC. Further information on this topic can
be found in the manual for your PC. Also check whether the scanner has been configured for the desired
application. This information is given in the User's Guide IT 1910i/1911i.
7. Check whether the bar code labels which you would like to scan are of suitable quality and that the used
bar code type is recognized by your scanner. Damaged bar code labels (crinkled, torn or soiled) may be
recognized poorly or not at all by the scanner. If you suspect that the problem lies with the quality of the
label, check the read readiness with a label of relatively good quality.
8. If the problems are still not corrected, please contact the Leuze electronic hotline (see chapter 8).
