Transmission Troubleshooting

Transmission fails; a communication error occurs.

Are the IP ADDRESS, SubNet Mask and Default Gateway settings correct?

Has the SMTP server been configured correctly?

If using DNS, is the DNS server address correct?

Check to make sure that the server is not down.

If DNS is ON, some servers may cause an error.

A network card I/F error has occurred - turn the power off and on again to recover.

The TIFF file sent cannot be printed out on the receiver.

Is the file sent at EX-FINE resolution or in coding mode other than MH? I-Fax simple mode Internet Fax products support only the STD and FINE resolution settings and MH coding mode.

The Sender ID is added to the subject when transmitted?

The Sender ID (Email) setting is ON and the subject is not entered. Either enter a Subject when sending an email or turn off the “Sender ID (Email)” on page 86.

I want to send it by PDF.

Is there a sufficient free memory space? Images have to be first stored in memory and cannot be received if there is not enough space. Have the message resent in smaller pieces if possible.

When receiving data manually, a warning message appears on the LCD.
