Fingerprint Sensor (ScanFront 220eP)
The ScanFront 220eP is equipped with a fingerprint sensor for registering fingerprints and authenticating users.
The fingerprint sensor is a precision component. Be careful when handling this sensor.
❏ Cautions for Handling the Fingerprint
Sensor
● The following actions may damage the fingerprint
sensor or cause it to malfunction. Read this
information carefully to avoid damaging the
sensor.
– 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, the
fingerprint sensor may be dirty. Clean the surface
of the fingerprint sensor regularly.

Fingerprint Sensor
● 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.
