Encrypting PDF files
Set a password to protect and encrypt a PDF file. Only users who have the password can open and decrypt the PDF file.
Encryption is possible only for scan files that are sent by e-mail or Scan to Folder and saved on a removable memory device.
You cannot open an encrypted file without a password. Make sure you do not forget a file's password.
Press [Send File Type / Name].
Check that [PDF] or [High Compression PDF] is selected.
Press [Security Settings].
Select [Encryption].
In [Encrypt Document], select [On].
In [Password], press [Enter].
Enter a password, and then press [OK].
The password entered here will be required to open the PDF file.
Enter the password again, and then press [OK].
In [Encryption Level], select [40 bit] or [128 bit].
Press [OK] twice.
A document password cannot be the same as the Master password.
Document passwords can contain up to 32 alphanumeric characters.
You cannot use Adobe Acrobat Reader 3.0 or 4.0 to view PDF files that were created using [128 bit] encryption.
If [Low Resolution Only] is selected as the print permission, you cannot select [40 bit] as the PDF encryption level.
