■ Setting the Management on the Hard Disk

In addition to the document data to be accumulated by FAX function, the registration
information of the Address Book and the password information of the System Box and the
Address Book are saved in the HDD of the host machine. Therefore, data management in the
HDD needs to be executed under a tight security measure.
The host machine has functions such as data encryption and data deletion and the data is
managed which prevents data leak to the outside so that the data is maintained safely and
confidentially.
● HDD Data Erase
The host machine saves the job data by dividing it into the management information area
and the actual data area at the time of copy, transmission/reception or print output. While the
management information is automatically deleted after job completion, the actual data is left
in the HDD.
Overwriting 0-data or random data can completely delete the actual data left in the HDD of
the host machine. This procedure is effective to prevent data leak to the outside when the
HDD is replaced or disposed.
