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.
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.
