The machine contains the Security functions (Data Overwrite Security and HDD Encryption unit) in the controller board.

If you are installing a new machine, it is recommended that you activate Data Overwrite Security and HDD Encryption by selecting "Format All Data" from “System Settings” on the operation panel.

  • This method is recommended because there is no user data on the HDD yet (for example, Address Book data, image data).

If the customer wishes to activate the Data Overwrite Security and HDD Encryption unit on a machine that is already running, it is recommended that you activate the unit by selecting "All Data" from “System Settings” on the operation panel.

  • Selecting "All Data" will preserve the data that has already been saved to the HDD. (If "Format All Data" is selected, all user data saved to the HDD up to that point will be erased).

Immediately after encryption is enabled, the encryption setting process will take several minutes to complete before you can begin using the machine.

  • If encryption is enabled after data has been stored on the disk, or of the encryption key is changed, this process can take three and a half hours or more.

The machine cannot be operated while data is being encrypted.

Once the encryption process begins, it cannot be stopped.

Make sure that the machine's main power is not turned OFF while the encryption process is in progress. If the machine's main power is turned OFF while the encryption process is in progress, the HDD will be damaged and all data on it will be unusable. When the HDD is broken, you should replace the HDD.

Back up the encryption key, and ask your customer to keep the encryption key in a safe place. For backing up encryption key, refer to "Backing Up the Encryption Key (Printer Model)" or "Backing Up the Encryption Key (MF Model)". If the encryption key is lost and is needed, refer to "Encryption Key Restoration".

Please use the following procedure when the Data Overwrite Security and HDD Encryption are reinstalled.
