Notes on using Internet Fax

When using the Internet Fax function, originals are sent at A4 size. Originals larger than A4 are reduced to A4 size. If the receiver's machine is compliant with the T.37 full mode, originals are sent at the size specified in the Address Book. For details about the T.37 full mode, see T.37 full mode.

If a transmission is not successful, this machine usually receives error notification e-mail. However, error notification e-mail may not be transmitted for various reasons. It is recommended that you confirm receipt of important document by calling the other party.

The level of security for Internet communications is low. It is recommended that you use the telephone network for confidential communications.

Voice communication is not supported over a LAN.

Internet Fax delivery might be delayed due to network congestion. Use Internet Fax transmission that bypasses the SMTP server, a public telephone line fax, or IP-Fax whenever communication time is a concern. For details about using this function, see Sending Internet Fax/E-Mail That Bypasses the SMTP Server.

You may not be able to send large files as e-mail, depending on e-mail environment conditions.

When available memory is low, you may not be able to send Internet Fax documents.

To view Internet Fax documents on a computer, an e-mail application that supports MIME and a viewer application compatible with TIFF-F files are required.

With a large volume of document, it may take some time before transmission starts. This is due to the time the machine requires to convert the data in memory.

If an e-mail message sent from this machine contains characters in a language other than English, the message might be garbled.

POP before SMTP is available in IPv4 environments only.
