In addition to the information in this section, please also refer to the 
documentation supplied with your USB device.

Reading of the 
fingerprint was 
not successful.

In this instance you should try the fingerprint reading 
operation again using the correct finger position - 
please refer to 

 in 

Chapter 4, 

, for further information.

Alternatively, you should try the recognition process 
again using another enrolled finger.

The fingerprint sensor compares and analyzes the 
unique characteristics in a fingerprint. However, there 
may be instances where certain users are unable to 
register their fingerprints due to insufficient unique 
characteristics in their fingerprints.

The recognition success rate may differ from user to 
user.

The fingerprint 
cannot be read 
due to injuries to 
the finger.

In this instance you should try the recognition 
process again using another enrolled finger. 
However, if fingerprints from all the enrolled fingers 
cannot be read, you should instead log into the 
computer by using the keyboard to input the 
password.

If you are still unable to resolve the problem, contact 
your reseller, dealer or service provider.

USB device does 
not work

Remove the USB device from the computer and then 
reconnect it to a free port in order to ensure it is firmly 
attached.

Ensure that any required USB device drivers are 
properly installed - to achieve this you should refer to 
both the device documentation and the operating 
system documentation.

If you are using an operating system that does not 
support USB, you are still able to use a USB mouse 
and/or USB keyboard by setting the USB KB/
Mouse Legacy Emulation option within the 
TOSHIBA HW Setup utility to Enabled.

If you are still unable to resolve the problem, contact 
your reseller, dealer or service provider.
