9 Trouble Shootings
Here are some useful tips to help improve the reliability of your ZKAccess
fingerprint reader(s):
1. A previous successfully enrolled finger cannot be subsequently matched,
then assume something has CHANGED since you last successfully enrolled
that same user’s fingerprint;
 Finger is dirty (try cleaning it)

Finger has a scratch (try enrolling a different finger)

Sensor is dirty (try cleaning with a lint-free cloth)
 Insufficient moisture on your finger (rub finger against your forehead or
cheek to obtain oil from your skin and try again)

Biometric reader has become damaged
2. But IF you CANNOT enroll any fingerprints, then try the following:
 Make sure finger(s) are clean and free from cuts or scratches.

Rub the finger you wish to enroll against your forehead (or cheek) to
obtain more oil from your skin and try again. This helps when in dry/cold
environments.

Lower the threshold setting on the reader (which desensitizes the
fingerprint scanner)
Change from 1:N matching to 1:1 matching (1:1 matching requires the user
first enter their User ID# prior to presenting their fingerprint).
IF ALL ABOVE TIPS FAIL
It’s possible the condition of your workplace (i.e. dirty/dusty), weather (very
cold/arid) or employee demographics (ages younger than 10 years or older
than 65 years) may contribute to less than optimal fingerprint recognition
results. If this is the case, inquire about alternative ZKAccess biometric
technologies (i.e. facial, finger vein pattern, etc.).
