6. Troubleshooting
This section presents methods for solving problems with the FV Scanner.
■ The USB cable is connected to FV Scanner, but the LED does not display a
green light.
This may be due to several reasons:
FV Scanner driver being used has not been appropriately configured.
→ See Chap. 2.4 Confirmation of Driver Installation in ”Device Driver and
Hitachi Secure BioAPI Runtime Libraries Installation and Un-installation
Manual” and verify that the driver has been properly configured on the PC.
PC USB port may be malfunctioning.
→ Restart the PC.
The hardware may be damaged.
→ Contact the retailer.
■ Authentication failure.
The finger has been moved during authentication.
→ Place the finger properly in the scanning area during authentication
and do not move it until the authentication process is completed.
The finger is wounded, excessively dry or dirty.
→When the finger is wounded, excessively dry or dirty, e.g. presenting dust or
other traces of dirt on its surface, a proper image will not be obtained during the
authentication process.
→ Wash or clean the hands, then perform authentication again using clean and
healthy fingers.
In the case of a finger width over 25 mm/1” or under 10 mm/0.4”, an appropriate
image might not be obtained and thus the image capture will not be completed.
→Perform a test of finger location: Try to extend the finger; place the finger
deep into the cavity; place the finger closer to the front.
General usage: Perform authentication by placing the fingertip on the
concave part of the FV Scanner.
The finger is not properly positioned.
→Place the finger properly into the scanning area, following the instructions
for authenticating.
Discrepancy between current finger condition and that stored at registration.
→ If it is difficult to complete authentication (i.e. with growing children, whose
finger condition changes), register the finger information again. For this new
registration, delete the previous finger information and perform Add Finger
Information again.
