After regenerating, all data is deleted since the full data initialization processing is executed
like when the security is started.
2.1.3 Full Initialization of the HDD
0008-5638
Function
With the specific timing as files are deleted (e.g. management information data is deleted)
from HDD, this function is to overwrite 0 (null) data and random data in file data areas and
delete the data in HDD completely.
In addition to the above real time processing, processing at start-up is added as a new
function. When the machine is started, data which was not deleted when the power was
turned OFF last time is deleted. In details, this is conducted when the power is turned OFF
during copying and the Secured Print job remains. During the start-up processing,
"Remaining data that is not needed is being erased. Do not turn off the main power" is
displayed on the screen. When starting or stopping the security kit operation, note that data
in the areas to be deleted are all deleted. If all data is deleted or there are much data remained
when the power is turned OFF, it takes much time to start up.
Note: Data deletion at the installation
When the security kit is installed, processing to fully initialize HDD automatically is
executed. Therefore, you need to backup beforehand.
The data deleted fully this way will be stored files (e.g. files in Boxes) and temporary files
(copy files, not visible from outside but nevertheless stored inside). Files stored
temporarily as PDL data (e.g. Network PDL Spool) will also be deleted.
If MEAP application is installed, you need to backup the license of MEAP application.
Depending on the Service mode settings, the deletion method is determined. As previous
devices, there is no setting of ON/OFF in User mode, and if the security kit is installed, this
will be enabled.
