Problem Cause Solution
I am unable to enrol a
finger.
1. The finger has not been
swiped
consistently over the
sensor, starting from the
first finger joint.
2. The finger has been
swiped too softly or too
strongly over the sensor.
3. The finger has been
swiped too fast or too slowly
over the sensor.
4. The way (angle) the finger
lays on the
sensor is not
right.
5. The finger does not have
enough minutia in order to
be enrolled (wearout).
1. Swipe the finger
consistently over the sensor
starting from the first finger
joint.
2. Swipe the finger gently,
but not too softly over the
sensor.
3.
Swipe the finger with
moderate s
peed over the
sensor (see page 37).
4. Use another finger.
An enroled finger cannot be
identified.
1. During enrolment, a
different area of the finger
was scanned.
2. The enrolment has not
been carried out correctly.
3. The finger is not being
swiped correctly over the
scanner.
1. The finger has to be
enroled again by swiping it
consistently over the sensor.
