Deleting Data on the Hard Disk
A Hard Disk
The machine’s hard disk lets you store data under the copy, printer, fax, scan-
ner, 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 fax numbers and data transmitted us-
ing the fax function, and network TWAIN scanner. Even if you delete the data
on the hard disk, this data remains intact.
Overwriting the Data on the Hard Disk
To use this function, the optional DataOverwriteSecurity unit must be installed.
To prevent data on the hard disk being leaked before disposing of the machine,
you can overwrite all data stored on the hard disk. You can also automatically
overwrite temporarily-stored data.
Note
Depending on the hard disk capacity and the method of erasing the data, this
action may take a few hours. Once you start the Erase All Memory function,
no other machine operation is possible until the function completes or you
quit the function.
