Fingerprint Sensor Frequently Asked Questions
We have included a collection of frequently asked questions related to the proper care and
maintenance of the fingerprint sensors provided with your NextgenID system.
Do I need to clean my sensor to keep it working well?
Depending on the amount of use, the sensor window will need to be cleaned from time to time. It
will pick up dirt and salts from fingers. Refer to the "Cleaning the Sensor" section above.
If a scratch or smear on the glass lens occurs, does this reduce performance? What is the
repair procedure if a failure occurs?
Scratches, pokes or other physical damage to the window coating can compromise the system's
ability to recognize fingerprints. Such damage cannot be repaired. Contact a NextgenID support
representative.
Will a buildup of dust on the sensor window reduce performance?
A small amount of dust on the sensor window will not cause problems. A large amount of dust
may make it more difficult for readings. Applying the sticky side of a piece of adhesive cellophane
tape on the window and peeling it away can easily remove dust.
My sensor window looks a little cloudy. What causes this and will it affect the sensor's
performance?
Under heavy usage, the window coating on some sensors may turn cloudy. This happens when
salt from perspiration builds up. The sensor window can be cleaned with a cloth dampened with a
mild ammonia-based glass cleaner. Do not pour the glass cleaner directly on the sensor window
and do not use alcohol-based cleaners.
What do I do if the coating comes off the sensor window?
The film on the sensor window is an integral part of the sensor. It is formed from a liquid silicone
with a special formula. If it comes off, the sensor sensitivity may decrease, resulting in reduced
performance. Rubbing the sensor or cleaning it incorrectly can cause the coating to come off.
Follow the cleaning instructions in the accompanying user guide to avoid this.
In the event that this does occur, please contact your NextgenID support team for additional
guidance.
