Encrypting PDF Files

This mode enables you to encrypt PDF files that you send to an e-mail address or file server for enhanced security.
If a password is set for a PDF file, only users who enter the correct password at the other party's machine can open, print, or change the received PDF.

For information on the optional products required to use this function, see "Optional Products Required for Each Function."

IMPORTANT
This mode can be used only if an e-mail address or file server is specified as the destination. If you specify a fax number or an I-fax address as the destination, you cannot send the job as an encrypted PDF file.

Press [Scan and Send] → specify the destination → press the file format button.

Select a file format → press [Set Details].

Press [Encrypt] → specify the settings as necessary.

If you select this key, you can specify detailed settings, such as <Allow Printing>, <Allow Changes>, and [Enable Accessibility, Copy, Extraction of Images].
Permission Password	Set the password required for assigning document permissions.
Store Password	Set [Password Required to Open a Document] or [Password Required to Change Permiss.] to 'On' → enter a password in [Password to Open a Doc.]. If a password is already stored, the stored password is automatically recalled when you press [Encrypt]. This is displayed when the user is logged in to the machine using SSO-H authentication.
