Encrypting PDF Files

You can create an encrypted PDF file simply by setting a password.

If you set a password for a PDF file, only users who enter the correct password can open, edit, or print the file.

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

IMPORTANT
If you did not enter a password in [Password to Open a Doc.] or [Permission Password], enter the password in the screen that appears when you press (Start). You can store the settings for encrypted PDF files in your Favorite Settings. If you do not want to set passwords for [Password to Open a Doc.] and [Permission Password] in [Favorite Settings], leave the passwords blank.

Even if you set restrictions for a PDF file with [Permission Password], some of the restrictions may be ignored if the reader opens the PDF with certain software.
