1.3 Fingerprint sensor cleaning and care
1.3.1 Cleaning for Fingerprint Sensors
Oily deposits from your finger accumulate on the surface of the fingerprint sensor after repeated use.
These can inhibit the functionality of the sensor.
Scheduled cleaning:
It is recommended to clean the sensor at least once a week, and also whenever an oily residue is
visible on its surface.
A sensor is designed to provide years of trouble- free service. Although
maintenance and handling requirements are few in number, observance of a
few basic maintenance procedures help ensure a high level of performance over
time.
Several types of sensors exist, and each type of sensor requires a different
cleaning method. Make sure to use the proper cleaning method for the sensor
type you use.
