Encrypting Data on the Machine

CAUTION

  • Keep SD cards and USB flash memory devices out of reach of children. If a child accidentally swallows an SD card or USB flash memory device, consult a doctor immediately.

Important

  • 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 machine or delete (initialize) 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

  • 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

  • Documents forwarded to the capture server

  • Files received via Mail to Print

  • Stored documents (stored documents in Document Server and Locked Print files / Sample Print files / Stored Print files / Hold Print files, and received and stored fax documents)

  • Registered stamps

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

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.
