Comm Error will show on the display if there is an issue on phoneline that were using.
First please check if the machine has a dial tone or try to call the fax # where you need to send the fax, just check if it's ringing.
Second before loading the paper make sure that the display shows date & time.
Then load the document in the tray the display should show enter fax # & start.
Start dialing the # then hit start.
you could try pressing the on hook dial button once you have a dial tone dial the fax number you are trying to reach and then you will be able to hear f there is a fax tone form the other machine or a error message from your operator. If there is a series of beeps with the document in the feeder press send.
The most common cause of not sending is ECM (Error Correction Mode) press menu and within TTI settings make sure this is turned off.
