Sony FIU-810 - Manual (Page 37)

Frequently Asked Questions (FAQ)
How does the FIU-810 unit read my fingerprint?
The Puppy® device offers robust fingerprint imaging technology based on a technique known as
capacitance, which digitally reads the fingerprint without leaving ink residue on your finger.
Capacitance sensors cannot be fooled by paper copies and do not require cleaning.
Do I need to clean the sensor?
No, the Puppy unit does not require regular cleaning. However, if you notice debris (dust, etc.)
collecting in the corners of the sensor area, you can clean the sensor with a dry tissue or cloth.
Can I enroll more than one user on the Puppy unit? Can more than one user logon to my
PC or domain?
No, the FIU-810 unit can only support up to 10 fingerprints from one user. To support multiple
users, each user must have their own FIU-810 device. Non-Puppy unit users can still login to a
Puppy Suite software-enabled PC using only their username and password, assuming of course
that they have existing user accounts on the computer or domain.
Why does my computer freeze or crash when I plug in the Puppy unit?
Be sure that you are connecting the Puppy unit directly to your PC’s USB port, or alternatively,
to a powered USB hub.
Why does my computer boot up slowly, or seem to stop, with the FIU-810 unit plugged in?
This is due to certain settings in your PC’s BIOS system; the PC may be looking at your FIU-810
device as a drive. Sony has noticed that some PCs will start up slowly (and may ‘appear’ to
freeze) at the system welcome screen (where the PC would typically say ‘VAIO’, etc.). The PC
will eventually boot, but to speed up this process simply disconnect your Puppy unit for a short
time until the PC continues to boot, and then plug it back in.
Why is the FIU-810 unit not reading my fingerprint when I try to enroll or use the device?
Be sure…
…the FIU-810 unit’s cable is firmly plugged into the unit and the PC’s USB port.
…the shutter is up, exposing the silver scanner surface.
…that your fingerprint is correctly placed on the device (see Section 1).
…if your finger is too dry, to touch your finger to your forehead or the side of your nose
and then place your finger on the unit. The oils will help the sensor to correctly read the
ridges and valleys of your fingerprint.
