About the Fingerprint Sensor
(ScanFront 220eP only)
The following actions may damage the sensor or
cause it to malfunction:
Dropping an object on the fingerprint sensor, or
otherwise subjecting it to a strong impact
Scratching the surface of the fingerprint sensor,
or poking it with a pointed object
Pressing a hard object such as a fingernail or
metal item against the fingerprint sensor,
resulting in scratches being created on the
surface of the fingerprint sensor
Touching the fingerprint sensor with dirty hands,
which might scratch or dirty the surface of the
fingerprint sensor
Placing a sticker on the surface of the fingerprint
sensor, or covering the surface with ink or
another substance
If fingerprint authentication fails frequently, clean
the surface of the fingerprint sensor regulary.
When cleaning the fingerprint sensor, use a soft
dry cloth to wipe dirt off the surface.
Do not use a pointed object to remove any dirt that
accumulates around the fingerprint sensor. Doing
so may cause the fingerprint sensor to
malfunction.
Touching the fingerprint sensor while charged with
static electricity may cause the fingerprint sensor
or device unit to malfunction. Before touching the
fingerprint sensor, discharge any static electricity
by touching a piece of metal. Be especially careful
during dry periods, such as the winter season,
when the likelihood of being charged with static
electricity is high.
