Encrypting Data on the Hard Disk

This can be specified by the machine administrator.
In order to use this function, the HDD Encryption Unit option is required.
Prevent information leakage by encrypting the Address Book, authentication information, and stored
documents as the data is written. In addition, if the machine malfunctions or needs to be replaced, your
service representative can easily transfer existing data to a new machine.
When the data encryption settings are enabled, an encryption key is generated and this is used to restore
the data. This key can be changed at any time.
Data that is Encrypted
This function encrypts data that is stored in the machine's NVRAM (memory that remains even after
the machine has been turned off) and on the Hard Disk.
The following data is encrypted:
• Address Book data
• User authentication information
• Data stored in the document box
• Temporary stored documents
• Logs
• Network I/F setting information
• System settings information

Enabling the Encryption Settings

Use the following procedure to enable the encryption settings at initial set up, or after encryption settings
have been canceled and settings must be made again.
• The encryption key is required for data recovery if the machine malfunctions. Be sure to store the
encryption key safely for retrieving back-up data.
• After completing the procedure on the machine's control panel, turn off the power and restart the
machine to enable the new settings. Restarting can be slow when there is data that needs to be carried
over to the hard disk. When you specify both overwriting and encrypting data on the hard disk,
encryption starts after the data is overwritten and the machine is turned off and on again. It can take
up to 12 hours until both functions are completed.
• You can start the machine in less time by setting encryption to [Format All Data] but data will not be
carried over to the hard disk and will be reset back to the default status, so make sure to back-up all
necessary data beforehand.
