Introduction

This Setup Guide explains the procedures for installing and operating the Data Encryption/Overwrite Functions (hereinafter called Security Functions) and the procedure for system initialization.
Organization administrators should read and understand this manual.

• Nominate a reliable person for the machine administrator when installing the security functions.
• Sufficiently supervise the nominated administrator so that it can observe the security policy and operation rules at the organization to which it belongs and properly operate the machine in accordance with the Operation Guide of the product.
• Sufficiently supervise the general users so that they can operate the machine while observing the security policy and operation rules at the organization to which they belong.

Instructions for General Users (for Both General Users and Administrators)

Security Functions

The security functions enable overwriting and encryption.
NOTE: If you install the security functions, Running security function… appears when the machine starts up and it may take a while.

Overwriting

Multi-functional products (MFPs) temporarily store the data of scanned originals and print jobs, as well as other data stored by users, on the SSD or in FAX memory, and the job is output from that data. As the data storage areas used for such data remain unchanged on the SSD or in FAX memory until they are overwritten by other data, the data stored in these areas is potentially restorable using special tools.
The security functions delete and overwrite (hereinafter collectively referred to as overwrite(s)) the unnecessary data storage area used for the output data or deleted data to ensure that data cannot be restored.
Overwriting is performed automatically, without user intervention.
CAUTION: When you cancel a job, the machine immediately starts overwriting the data that was stored on the SSD or in FAX memory.
Encryption
MFPs store the data of scanned originals and other data stored by users in the SSD. It means the data could be possibly leaked or tampered with if the SSD is stolen. The security functions encrypt data before storing it in the SSD. It guarantees higher security because no data cannot be decoded by ordinary output or operations. Encryption is automatically performed and no special procedure is required.
CAUTION: Encryption helps enhance security. However, the data stored in the Document Box can be decoded by ordinary operations. Do not store any strictly confidential data in the Document Box.

Security Functions

Touch Panel Display after the Security Functions are Installed

Hard Disk Icon Display In Security Mode, the security functions have been properly installed and is running. The hard disk icon appears on the top right side of the touch panel in Security Mode.
NOTE: If the hard disk icon does not appear on the normal screen, it is possible that the Security Mode is not ON. Call service.
The hard disk icon display changes as follows during overwriting
The table below shows the icons displayed and their descriptions.

CAUTION: Do not turn the power switch off while is displayed. Risk of damage to the SSD or FAX memory.
NOTE: If you turn the machine off at the power switch during overwriting, data may not be overwritten completely from the SSD. Turn the machine back on at the power switch. Overwriting automatically resumes. If you accidentally turn the main power switch off during overwriting or initialization, the icon might not switch to the second icon shown above. This would be caused by a possible crash or failed overwriting of the data to be overwritten. This will not affect subsequent overwriting processes. However, hard disk initialization is recommended so as to return to normal stable operations. (Initialization should be performed by the administrator following the steps in System Initialization on page 15.)
Instructions for Administrators (for Those in Charge of Installation and Operations of the Security Functions)
If any kind of problem occurs in the installation or use of the security functions, contact your dealer or service technician.

Installing the Security Functions

The Security Functions Contents
The security functions package includes:

• License Certificate
• Installation Guide (for service personnel)
• Notice In case of the standard specification, there will be no bundled items included.

Before Installation

• Make sure that the service representative must be a person who belongs to the supplying company.
• Install the machine in a safe location with controlled access, and unauthorized access to the machine can be prevented.
• The SSD will be initialized during installation of the security functions. This means that the data stored in the hard disk will be all overwritten. Special attention should be given if you install the security functions on the MFP currently used.
• The network to which the machine is hooked up must be protected by a firewall to prevent extraneous attacks.
• [Adjustment/Maintenance] -> [Restart/Initialization] -> [System Initialization] will not be displayed in the System Menu after the installation.
• When installing the security functions, change the machine settings as follows.

Change the administrator password.
Device Settings| Date/Timer| Date and Time| Set the date and time.

Installation

Installation of the security function is performed by the service person or the administrator. The service person or the administrator should log in the system menu to enter the encryption code.
Encryption Code
An encryption code of 8 alphanumeric characters (0 to 9, A to Z, a to z) to encrypt data needs to be entered. By default, the code is set 00000000. As an encryption key is then created from this code, it is safe enough to continue using the default code.
CAUTION: Be sure to remember and securely manage the encryption code you entered. If you need to enter the encryption code again for some reason and you do not enter the same encryption code, all the data stored on the SDD will be overwritten as a security precaution.
Installation Procedure
Use the procedure below to select the interface.

1. Press the [Home] key.

2. Press […] [System Menu] [Add/Delete Application].

3. Press [Optional Function List] of Optional Function.
   If user login is disabled, the user authentication screen appears. Enter your login user name and password and then press [Login]. For this, you need to log in with administrator privileges. Refer to the machine’s Operation Guide for the default loginuser name and password.

4. The optional function screen is displayed. Select Data Encryption/Overwrite and press [Activate].

5. This function will be activated. The data saved in the large capacity storage will be deleted and the storage will be formatted and encrypted. If there is no problem, press [Yes].

6. Turn the power switch on again following to the indication in the panel screen.

7. The screen for entering the encryption code is displayed.
   To change the encryption code, erase the “00000000” and then enter the 8-digit alphanumeric encryption code (0 to 9, A to Z, a to z) and press [OK]. SSD formatting begins.
   If the encryption code is not changed, press [OK]. SSD formatting begins.

8. When formatting finishes, follow the on screen instructions to turn the Power Switch off and on again.

9. After the opening screen is displayed, confirm that a hard disk icon (Overwritten completion icon of unnecessary data) is shown in the top right corner of the screen.

After Installation
Change the machine setting as follows to securely operate it. If the system in the machine is initialized, it returns to the settings before installation, so make changes in the same way. If you allow service personnel to conduct maintenance operations, confirm the set values.

Items changed on the machine

For the procedures for changing the settings, refer to the machine Operation Guide and Command Center RX User Guide.
After changing the settings, run [Software verification] in the system menu to verify that the machine operates correctly. Periodically perform [Software verification] after installation as well.
After installing the security functions, you can change the security password. Refer to page 14 for the procedures.
The administrator of the machine should periodically store the histories, and check each history to make sure there was no unauthorized access or abnormal operation.
Grant regular users permission based on your company rules, and promptly delete any user accounts that stop being used due to retirement or other reasons.
IPsec setting
It is possible to protect data by enabling the IPsec function that encrypts the communication path. Please note the following points when enabling the IPsec function.

• The value set by the IPsec rule has to be matched with the destination PC. Communication error occurs in case the setting does not match.
• IP address set by the IPsec rule has to be matched with the IP address of the SMTP server or FTP server which is set on the main unit.
• In case the setting does not match, data sent by mail or FTP can’t be encrypted.
• Pre-shared key set by the IPsec rule has to be created by using the alphanumeric symbols of 8 digits or more which will not be easily guessed.
