Closed Network RX is a function that restricts fax senders by passwords.
When receiving a fax, the machine checks the password sent from the sender against the password preset for this machine and, if they match, accepts transmission. Restricting fax senders helps to reduce unnecessary printing and wasteful paper use.
You can use this function only when the remote machine is one of our models that has Password TX function.
Optionally, you can use the Password TX function to send a fax with password to a destination for which Closed Network RX is specified. For details on the Password TX function, refer to Here.
Enable the Closed Network RX function. Specify the password to restrict the communication.
