13. 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 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. ● 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. 34
