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 220P)
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.
