❖ Remove static electricity from your fingers by touching
any metal surface. Static electricity is a common cause
of reader failures, especially during dry seasons such as
winter.
❖ Clean the reader with a lint-free cloth. Do not use
detergent to clean the reader.
❖ Avoid the following finger conditions for enrollment or
recognition as they may result in fingerprint enrollment
errors or a drop in the fingerprint recognition success
rate.
❖ Soaked or swollen finger (e.g., after taking bath)
❖ Injured finger
❖ Wet finger
❖ Soiled or oily finger
❖ Extremely dry skin condition on finger
Observe the following to improve the fingerprint recognition
success rate.
❖ Enroll two or more fingers.
❖ Enroll additional fingers if recognition failure occurs often
using enrolled fingers.
❖ Check your finger condition. Changed conditions, such
as injured, rough, extremely dry, wet, soiled, dirty, oily,
soaked or swollen fingers, may lower the recognition
success rate. Also if the fingerprint is worn down or the
finger becomes thinner or fatter, the recognition success
rate may be lowered.
❖ The fingerprint for each finger is different and unique.
Please ensure that only the registered or enrolled
fingerprint or fingerprints are used for identification.
❖ Check sliding position (see illustration below).
