You can use the hard disk of your imageRUNNER ADVANCE machine to perform numerous convenient operations including copying, sending/receiving, and storing data. Even if the hard disk is removed from the machine, it is virtually impossible to analyze the data stored in the disk. The figure below shows a comparison of the hard disks of imageRUNNER ADVANCE machines and computers.

For Computers
 Hard disk
|
 |
Data is separated for storage into 'Management Information', such as the file name, and 'Actual Data', the content of the data.
|
 |
Operations that erase data (e.g. emptying the recycle bin, formatting, etc.) only erase 'Management Information'. Actual data remains hidden in the hard disk.
|
|
 |
You can restore actual data hidden on the hard disk using file restoration software.
* Management information contains the file name of the actual data, storage location on the hard disk, directory name, date created, and other data information.

 Hard disk

Data is separated for storage into 'Management Information', such as the file name, and 'Actual Data', the content of the data. Management information is managed using a method exclusive to imageRUNNER ADVANCE machines.
|
|
|
Management information is erased following copy, send/receive, and printing operations. However, actual data remains hidden in the hard disk.
|
|
 |
You cannot access actual data in the machine's hard disk from the machine's display or a network computer. Also, removing and analyzing the machine's hard disk is made virtually impossible due to the need to analyze Canon confidential imageRUNNER ADVANCE firmware and data compression technology in the process.

By using the data erase kit, you can completely erase all actual data. This helps to strengthen an already robust security system.
* The HDD Data Erase function performs processing in real-time, avoiding batch processing. This function also enables you to suppress job log data.
|
You can manually erase all user data stored in the machine when discarding or moving the machine.
This section describes how to initialize all data and settings contained in the hard disk of your machine.
The screens may differ, depending on the model of the machine and on attached optional products.
1.
Press 
(Settings/Registration) → [Management Settings] → [Data Management] → [Initialize All Data/Settings].
(Settings/Registration) → [Management Settings] → [Data Management] → [Initialize All Data/Settings].
2.
Press [Yes].
|
NOTE
|
|
It may take more than 30 minutes to initialize the hard disk.
|
3.
After the hard disk is initialized, the control panel power switch automatically turns OFF and the main power switch of the machine automatically switches to OFF.
You can use HDD Data Encryption to automatically encrypt actual data when storing your digital files in the hard disk using the Mail Box, Fax, and other functions.
In addition, you can automatically erase all job data from the machine.
This function enables you to encrypt all data, including temporary data, at the time of writing.
Even if the hard disk is removed from the machine, data in the disk cannot be decoded without the electronic key, helping prevent the leakage of confidential information such as Address Book and Mail Box data.
Your imageRUNNER ADVANCE machine separates data into management information and actual data before storing the data.
Management information is automatically erased when the copy, send/receive, or print operation is completed. However, actual data is stored and remains in the hard disk.
By using the Security function, actual data (image, management, and spool data for the copying, mail box, printing, and sending/receiving functions) is erased at the same time as management information.
|
NOTE
|
|
Temporary job data that is created in the hard disk is automatically erased when the job completes.
An erase method can be selected according to a company's security policy from the following four options:
[Once with 0 (Null) Data]: Overwrites the data once with 0 (null) data.
[Once with Random Data]: Overwrites the data once with random data.
[3 Times with Random Data]: Overwrites the data three times with random data.
[DOD Standard]: Overwrites the data three times. The first time is with a fixed value, the second time with a complement of the fixed value, and the third time is with random data.
