Changing the 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 passphrase, 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.
