2.1.18 HDD Data Erase Kit
0020-7937
The earlier iR Security Kit was a function that enabled the complete erasure of all user data, as well as user data encryption and decryption. As the data encryption
is performed by software, when using functions that temporarily store data on the main unit HDD, such as copy, scan, print and box, performance falls by more
than 20% in comparison with when such functions are not being used. Also, the used data erase operation may cause a drop in performance.
The HDD Data Encryption Kit performs encryption and decryption by hardware, without any loss of performance. The HDD Data Encryption Kit allows the user
to guard against the leaking of user data due to theft of the hard disk. However, data pertaining to copy, scan, print and box functions will remain on the hard disk
after the Data Encryption Kit has been used so, in order to guard against unauthorised viewing by a malicious third party, it was necessary to use the iR Security
Kit in addition.
With the HDD Data Erase Kit, copy, scan, print and box data can be automatically erased after use, without using the iR Security Kit, thus preventing unauthorised
viewing. Also, use of the HDD Data Erase Kit results in no loss of performance and allows the user to prevent user data from being leaked due to theft of the hard
disk. However, with the Data Erase Kit, the data erase operation will result in some loss of performance, as with the iR Security Kit.

Types of user data erased
Once the HDD Data Erase Kit is activated, all unnecessary data and deleted data on the hard disk can be completely erased.
The erasure timing and erasure mode can be selected with the HDD Data Erase Kit.
The following data are erased.
- temporary image data generated when a scan is made
- cascade copy/ remote copy transmission and reception data
- residual data after box texts have been deleted
- fax/ i-fax transmission and reception data
- spool data
- temporarily stored print data
HDD Data Erase
HDD Data Erase can be performed in either of the following two ways.
- Turn the host machine's main power supply OFF/ ON.
- HDD Data Erase will be performed automatically after copy, scan, print or box operations.
Turn the host machine's main power supply OFF/ ON
When the HDD Data Erase Kit has been activated, once the host machine's main power supply is turned ON, all data in the HDD are erased. In such cases, the
following message will be displayed for a few minutes, after which time the touch panel will be operational.
-----------
Remaining data that is not needed is being erased.
Do not need turn off the main power.

HDD Data Erase timing settings
Additional Functions > System Settings > Hard Disk Data Complete Erase Set > Erase Timing > During job or After job
If the user frequently outputs documents with multiple pages, selecting [After job] means that the erasure will be done after the job is finished, so the erasure
time is not included in the processing time.
When outputting multiple jobs in sequence, selecting [During job] means that the time waiting between jobs is shortened.
HDD Data Erase mode settings
Additional Functions > System Settings > Hard Disk Data Complete Erase Set > Erase Mode >
0 (Null) Data 1 time
Random data 1 time
Random data 3 times
The more the number of write operations increases, the more loss of performance there will be during jobs.
Related service modes
The Data Erase Kit is a function for erasing data after they have been used by the main unit.This has nothing to do with the erasure of user data at lease renewal.To erase user data all
at once, including address tables, use the following user mode, as in the past.
