and document server functions, as well as the address book and counters
stored under each user code.
B Data Not Overwritten in the Hard Disk
The machine's memory lets you store data transmitted using network
TWAIN scanner. Even if you delete the data on the hard disk, this data re-
mains intact.

Overwriting the Data on the Hard Disk
