Procedure for encrypting PDF files (classic)

Set a document password to protect and encrypt a PDF file. A document password cannot be the same as the master password.

Only users who have the password can open and decrypt the PDF file.

Important

  • Encryption is possible only for scan files that are sent by e-mail or Scan to Folder and saved on a memory storage device.

  • You cannot open an encrypted file without a document password. Make sure you do not forget the file's password.
