4.2.4 User data Erase of the HDD
0020-7977
If the host machine is used by a user for such cases as demonstration, clear the address book for FAX and the user data on HDD completely and remove the machine
from the user's site.
The following are the method to clear HDD completely.
For a machine where the HDD Data Encryption Kit is installed
When clearing the key information with SST, the encryption key of the main controller becomes not identical to that of HDD and all data in the HDD cannot be
read.
All data in HDD are targeted. When using the same HDD in the host machine, the following tasks are required.
1) HDD format
2) System installation
In the case that the HDD Data Encryption Kit is not installed
Additional Functions > System Settings > Initialise all Data/ Settings
If the HDD Data Erase Kit has been installed, the setting in service mode enables overwriting the 0 data and random data to the data area on the deleted HDD and
makes decryption more difficult.

0020-7978
The procedure is described in order to improve understanding of WebDAV through the experiment.
For practical use, many anti-virus measures or countermeasures against security are necessary.
The environment created by the procedure must not be connected to the outside or LAN environment because it is highly likely to be the target for attacks targeting
IIS.
WebDAV works on the IIS. Therefore, before starting the installation of WebDAV, IIS should be enabled in Windows 2000 Server or Windows 2003 Server.
