Scanning does not start Have you placed your finger cor-
rectly on the authentication unit? Confirm how to perform authen-
tication and how to place your
finger when scanning. (p. 10-2)
During scanning, place the
scanned part on the scanning
section correctly, and do not
move it until results have been
obtained.
If the scanned part is dusty or
rough and dry when performing
authentication, a correct image
will not be able to be obtained,
and scanning may not finish.
Clean your finger, and then scan
it again, or improve the rough
and dry condition of your finger.
If the scanned part is too thick or
thin (when the finger width is out-
side the range from 3/8 to 1 inch
(10 to 25 mm)), a correct image
cannot be obtained, and scan-
ning may not finish. Try "stretch-
ing your finger", "placing your
finger deeply", or "placing your
finger shallowly" on the scanning
section.

hardware uninstall wizard Is the USB port to which the au-
thentication unit is connected the
same as the one used when in-
stalling the driver? If you connect the authentication
unit to a different USB port from
the one used when installing the
driver, the hardware uninstall
wizard may start. Use the same
USB port as the one used when
installing the driver.
