Troubleshooting Fingerprint Sensor Problem Procedure 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 Using the Fingerprint Sensor in Chapter 4, Operating Basics 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. User's Manual 8-17
