# T.37 Full Mode

This machine is T.37 full mode compatible. T.37 full mode is an international standard for Internet Fax transmission. (ITU-T Recommendation, RFC2532)

When an Internet Fax communication is made between T.37 full mode compatible machines, the receiver side sends the return receipt (dispatched) in response to the reception notice request attached to the sent e-mail. This return receipt includes the receiver's reception capability information (compression type, paper size, and resolution). When the receiver is programmed in the Address Book as the full mode destination, the sender side automatically registers the received information in the Address Book. This allows you to send a subsequent Internet Fax document to that receiver based on this information.

Returning a Return Receipt

When e-mail is received, if the sender requests reception notice, the receiver sends a return receipt that includes the receiving machine's capability (compression type, paper size, and resolution).

Registering the Received Reception Confirmation Contents

When the sender receives the return receipt that includes the receiver's reception capability, the sender checks that the final recipient address sent is programmed in the Address Book. If it is programmed as a full mode destination, the sender automatically registers the receiver's reception capability. The registered reception capability is updated each time the sender receives new reception capability information. The sender can send documents to the receiver based on this information.

If the receiver is programmed as the simple mode machine or not programmed in the Address Book, the receiver's reception capability cannot be registered.

If you know the receiver's reception capability, you can set it manually.

Requesting a Reception Notice

When the receiver's machine supports T.37 full mode and is programmed as a full mode machine in the Address Book, the machine requests the reception notice from the receiver. Then, the machine will receive the return receipt (sent) that includes the receiver's reception capability.

- For details about requesting reception notice from this machine, see “Requesting a Reception Notice”.

- Use Web Image Monitor to manually program a receiver's reception capability information. For details about programming receiver's information, see “Programming Destination Information from Web Browser”.

- If you use Internet Fax transmission, you can send documents to multiple destinations at once. However, if you specify full mode destinations, since each destination may have a different reception capability, transmission is done one by one in the specified transmission order.
