- Auto: The line is switched automatically.
- Line 1: The 1st line is used.
- Line 2: The 2nd line is used.
 Mailbox Communication
For the communication compatible with ITU-T (International Telecommunications Union-
Telecommunications) standards, specify a subaddress or password to be sent to the recipient's
fax machine. (Up to 20 digits can be entered.)
- SUB (Subaddress): Information to send data of the original to the fax machine.
- SEP (Selective Polling): Information to retrieve data of the original from the fax machine.
- SID (Sender Identification): Password for SUB.
- PWD (Password): Password for SEP.

- Subject: The subject of the Internet Fax.
- Body: The body of the Internet Fax.
 Both the sender and the receiver must have the ECM function to make ECM communication
available.
 When affected by noise during communication, communication time is slightly longer than
usual. Even when the ECM communication is used, an error may occur depending on the line
status.
 The ECM communication is not available for voice communication.
 The setting condition in the address book takes the priority. Therefore, when the recipient's
Quality Tx setting is set to On in the address book, a fax transmission is performed at On even
though the Quality Tx setting remains Off in the Option screen.
To use the Mailbox Communication function, the recipient's fax machine must be capable of
setting an ITU-T compatible subaddress or password.
