Chapter 9 Maintenance

1. Routine Cleaning

Clean the scanner on a regular basis, as described below, to maintain scanning performance.

CAUTION

• When cleaning the scanner, do not spray water or detergent

directly on the scanner. Doing so may damage precision

mechanisms, such as the light source.

• To clean the fingerprint sensor, use a dry commercially available

cotton swab or a dry cloth to wipe off any dirt. If a cloth containing

water or another liquid is used, the scanner may malfunction as a

result of liquid getting inside the scanner.

• Never use thinner, alcohol, or other organic solvents to clean the

touch panel. Such solvents may deform, discolor, or melt the

touch panel, thus causing a malfunction.

❏ Cleaning the Scanner Unit

To clean the surface of the scanner unit, use a cloth slightly

dampened with water and well wrung out, to remove any

dirt, and then use a clean, dry cloth to wipe the scanner.

❏ Cleaning the Touch Panel

When cleaning the touch panel, use a soft, dry cloth to

gently wipe the surface of the panel without applying

pressure.

❏ Cleaning the Fingerprint Sensor

(ScanFront 300P)

To clean the fingerprint sensor, use a soft, dry cloth to wipe

off any dirt.

IMPORTANT

The portion of the sensor where the fingers touch during

fingerprint authentication can get particularly dirty. A dirty

sensor may cause fingerprint authentication errors. Clean the

sensor and its surrounding area regularly, regardless of how

dirty they are.
