This function is only available for the standard hard disk. If your machine is equipped with the Enhanced Security HDD Option, data on the hard disk is always encrypted. Therefore, this function can only encrypt the machine's NVRAM data.
Even if the memory device or hard disk is stolen, data leakage can be prevented by encrypting the data on the machine, such as Address Book, authentication data, and files.
Once encryption is enabled, all data subsequently stored on the machine will be encrypted.
You can also choose to encrypt or delete the data currently stored on the machine.
The encryption algorithm is AES-256.
Data that is encrypted
This function encrypts data that is stored in the machine's NVRAM (memory that remains even after the machine is turned off) and on the hard disk.
The following data is encrypted:
NVRAM
System settings information
Network I/F setting information
User code information
Counter information
Hard disk
Address Book
Embedded Software Architecture applications' program/log
Logs (Job log/access log/Eco-friendly log)
Sent/received e-mail
Registered fonts
Spooled jobs
Thumbnails of stored documents
Stored documents
Registered stamps
Type of Encryption
Specify whether to encrypt existing data and keep it on the hard disk or delete (format) it. Encryption takes time if a large amount of data is to be kept. The NVRAM data will not be deleted (initialized).
Setting |
Data to be kept |
Data to be initialized |
Required time |
---|---|---|---|
File System Data Only |
|
|
Approx. 2 hours 15 minutes |
All Data |
All Data: Both the data to be kept and not to be kept when [File System Data Only] is specified |
None |
Approx. 5 hours 30 minutes |
Format All Data |
None |
All Data: Both the data to be kept and not to be kept when [File System Data Only] is specified |
Several minutes |
Notes for enabling encryption settings
If you use Embedded Software Architecture application or App2Me, be sure to specify [File System Data Only] or [All Data].
Note that the machine's settings will not be initialized to their system defaults even if [Format All Data], [File System Data Only], or [All Data] is specified.
Restoring Data
To transfer data to a new machine, restore the encrypted data. For details, ask the service representative.
The encryption key used for data encryption is required to restore the data.
You can specify whether to print the encryption key or store it on an SD card.
You can change the encryption key later.
