Appendix A: General Maintenance Tasks
Fingerprint Sensor Hardware Maintenance
Each enrollment kit contains a
Digital Persona
fingerprint-imaging device. Periodic maintenance
of the fingerprint sensor is necessary to maintain quality enrollment templates and sensor life.
Cleaning the Sensor
Depending on the amount of use, the sensor window may need to be cleaned periodically.
To clean it, apply the sticky side of a piece of adhesive cellophane tape on the window and peel it
away.
Under heavy usage, the window coating on some sensors may turn cloudy from the salt in
perspiration. In this case, gently wipe the window with a cloth (not paper) dampened with a mild
ammonia-based glass cleaner.
Sensor Maintenance Warnings
There are several things you should never do when cleaning or using the sensor
•
Do not pour the glass cleaner directly on the sensor window.
•
Do not use alcohol-based cleaners.
•
Never submerge the sensor in liquid.
•
Never rub the window with an abrasive material, including paper.
•
Do not poke the window coating with your fingernail or any item, such as a
pen.
