Changing the Encryption Passphrase

Encryption Passphrase

An encryption passphrase is information used for encrypting the password that is sent to this machine for printing using the printer driver.

When printing is executed, some functions may send an authentication password such as the user password or account password. The password is encrypted using the encryption passphrase specified in advance in this machine. However, you can change the encryption passphrase when necessary.

To change the encryption password, you need to set the same encryption passphrase in this machine and in the printer driver.

Tips

  • If the encryption passphrase set in this machine differs from the one set in the printer driver, printing cannot be executed because this machine cannot decrypt the encrypted password.

Operations required to use this function (for the administrator)

  1. Tap [Utility] - [Administrator Settings] - [Security Settings] - [Driver Password Encryption Setting].

  2. Select [User-Defined] and tap [Encryption Passphrase].

  3. Tap [Encryption Passphrase] and enter the new encryption passphrase (using up to 20 alphanumeric characters, including symbols).

    supplementary explanationTap [Encryption Passphrase Confirmation], then enter the encryption passphrase again.

    supplementary explanationAn encryption passphrase using a series of the same letters (for example, "1111") is invalid.

  4. Tap [OK].

    This sets the encryption passphrase.

Setting the printer driver

preconditionDo not perform the following steps when you do not want to change the encryption passphrase on this machine.

  1. In [Output Method] window, click [Detail Settings...].

  2. Select [Administrator Settings], then click [Settings...].

  3. Select the [Encryption Passphrase:] check box and enter the encryption passphrase (using up to 20 alphanumeric characters, including symbols) that you have set on this machine.

    supplementary explanationDo not select the [Encryption Passphrase] check box unless you want to change the encryption passphrase on this machine.

  4. Click [OK].

Printing procedure

  1. On the [Output Method] tab, set up the print function which uses the password for [Secure Print], [Save in User Box], [User Authentication] and others.

  2. Execute printing.

    The password is encrypted with the encryption passphrase being set by the printer driver, and the encrypted password is transmitted to this machine. The password is decrypted with the encryption passphrase being set on this machine, and it is printed out or stored in the box.
