Networks

Option 1: create a common share...
\\server\folder
which is really c:\folder (on the server)
in this folder create a folder for each user
c:\folder\user01
c:\folder\user02
...give Administrator, the scanner, and each user permission to each folder.

Option 2: configure the copier to scan to individual e-mail mailboxes, then when the user goes to scan they should pick their own name from the front panel
