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 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 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 Fingerprint Sensor (ScanFront 300P) To clean the fingerprint sensor, use a soft, dry cloth to wipe off any dirt. Fingerprint Sensor 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. 9-2
