Fujitsu Scansnap 1300i Question

I have a Fujitsu Scansnap s1300i scanner connected to my iMac via USB. The scanner works perfectly. However, it does not show up on the list of scanners connected to the computer. Does anyone know why, or how to correct this?

The reason for the request is that I would like to share it via my computer on the network, but because it doesn't show up this does not seem to work.

Thanks for any help.
