Cleaning the Sensor
Under normal use it is not necessary to clean the fingerprint sensor every day, however from time to time and es-
pecially in dirty environments cleaning the will help ensure reliable performance. If only minor cleaning is needed,
use a lint-free cloth and carefully wipe the sensor surface. If a more thorough cleaning is needed, follow the method
presented below.
You will need the following,
Lint-free cloth OR cotton swab.
Isopropyl alcohol (IPA)
How to clean:
1) Put a small amount of IPA on a lint-free cloth or cotton swab. Only a small amount is needed to make the cloth
or cotton swab slightly damp. If the surface is heavily contaminated with a greasy substance the amount of IPA
should be increased so that the contaminant can be fully dissolved. Do not pour the IPA directly onto the
reader.
2) Gently rub the cloth or cotton swab over the whole sensor surface. Make sure to reach the area close to the
frame where dirt/grease can accumulate.
3) Use a dry piece of cloth or cotton swab and wipe the sensor surface dry. Look carefully at the sensor surface
and make sure that no residual liquid remains on the sensor.
4) Repeat the process if necessary.
Avoid using detergents and soaps containing oily substances since they can leave contaminants that negatively
i
effect the sensor performance.
