Points to note about Fingerprint Utility

Qosmio X870/X875 series

Clean the sensor with a lint-free cloth - do not use detergent or any other chemicals to clean the sensor.

Avoid the following finger conditions for enrollment or recognition as they may result in fingerprint enrollment errors or a drop in the fingerprint recognition success rate

Soaked or swollen finger, for example as may occur after taking a bath.

Injured finger

Wet finger

Soiled or oily finger

Extremely dry skin condition on finger

Observe the following to improve the fingerprint recognition success rate.

Enroll two or more fingers.

Enroll additional fingers if a recognition failure often occurs when using already enrolled fingers.

Check the condition of your finger - any conditions which have changed since enrollment, such as injury, rough skin, and extremely dry, wet, soiled, dirty, oily, soaked or swollen fingers, may lower the recognition success rate. Also if the fingerprint is worn down or the finger becomes thinner or fatter, the recognition success rate may be lowered.

As the fingerprint for each finger is different and unique you should ensure that only the registered or enrolled fingerprint or fingerprints are used for identification.

Check the position and speed at which you swipe your finger across the sensor - please refer to the preceding drawing.

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.
