Prevent information leakage by encrypting the Address Book, authentication information, and stored documents as the data is written.
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 printer's NVRAM (memory that remains even after the printer has been turned off) and on the hard disk.
The following data is encrypted:
Address Book data
User authentication information
Temporary stored documents
Logs
Network I/F setting information
System settings information
If the printer needs to be replaced, the existing data can be transferred to a new printer, even if the data is encrypted. To transfer data, contact your service representative.
You can back up the printer's data encryption key to an SD card. For details about SD card handling, see "Inserting/removing a memory storage device", Operating Instructions.
Time required for encryption
When setting up encryption, specify whether to start encryption after deleting data (initialize) or encrypt existing data and retain it. If data is retained, it may take some time to encrypt it.

Notes for enabling encryption settings
If you use Embedded Software Architecture application or App2Me, be sure to specify [CarryOver FileSys DataOnly] or [Carry Over All Data]. (for SP C340DN)
If you use Embedded Software Architecture application or App2Me, be sure to specify [File System Data Only] or [Carry Over All Data]. (for SP C342DN)
Note that the printer's settings will not be initialized to their system defaults even if [Format All Data], [CarryOver FileSys DataOnly], or [Carry Over All Data] is specified. (for SP C340DN)
