Transmission Troubleshooting

Transmission fails; a communication error occurs.

See if the server is down.

Are the IPADDRESS, SubNetMask and Default Gateway settings correct?

Has the SMTP server been configured correctly? Has the host name been registered?

If using DNS, is the DNS server address correct? If DNS is ON, some servers may cause an error.

Display shows message “OPTION BOARD ERROR.”

An error may have occurred at the interface between the fax machine and the network card.

Turn off the fax machine. Verify that the network card is correctly installed. Turn the machine on.

I have turned MDN (or DSN) ON, but no confirmation has been returned.

Both MDN and DSN are sent as text-format messages. If the TEXT PRINT setting is OFF, the confirmations will not print.

MDN: If the receiving Internet Fax/e-mail client is not capable of receiving MDN, you may not get a receipt.

DSN: If the receiving server does not support DSN, you may not receive any confirmation.

The TIFF file I sent does not print out at the receiver.

Resend the file, making sure to use Standard resolution and MH coding.

If you sent the file using Ex-fine resolution or any coding mode other than MH, the receiving machine may not be able to work with the file.

T.37 simple mode Internet Fax products support only the STD and FINE resolution settings and MH coding mode.
