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.
