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.
