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 sent by e-mail or Scan to Folder.
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.
You can enter up to 32 alphanumeric characters for a document password.
PDF files created under the [128 bit] Encryption Level cannot be viewed using Adobe Acrobat Reader 3.0 and 4.0.
If [Low Resolution Only] is selected as the print permission, you cannot select [40 bit] as the PDF encryption level.
