Encryption
This method allows you to communicate with originals encrypted by the sending system. Therefore, even when a third
party tries to view the originals in the middle of communication by some means, the third party is prevented from
knowing the actual contents of the originals. The originals received are reverted to the originals as they were before
transmission (decrypted) by the receiving system, and printed. This is an extremely effective communication method for
sending confidential documents that are not to be opened by a third party.
In encryption communication, in order to encrypt and decrypt originals, the sending and receiving systems must use the
same 16-digit encryption key. When the encryption key differs between the sending system and the receiving system,
the encryption cannot be conducted. Therefore, the sending system and the receiving system need to have the same
encryption key and 2-digit key No. registered in advance.
Description of settings at sending and receiving systems
*1 When the machine receives originals, the Encryption Box is not used.
Registering an Encryption Key
An encryption key is required when registering the Address Book used for encryption communication (the other party is
directly entered using the numeric keys) in the sending system and when setting encryption in the receiving system.
For the creation of the encryption key, numbers from 0 to 9 and letters from A to F are arranged to form 16 numbers and/
or letters arbitrarily. The created encryption key is registered with a 2-digit key No. (01 to 20).
In order to use encryption communication, the fax of the other party needs to be an our-brand system
with the same type of encryption functions.

Set the same characters for the numbers indicated by the same letter in parentheses. For example, the same
characters should be used as the encryption key (C) in both the sending and receiving systems.
Up to 20 encryption keys can be registered.
