New HP 640 fax has been working fine until we tried to fax something to a fax number with the area code of 817 (Texas). Faxes to this area code will not go through. Local faxes and faxes to numbers in our state (Tennessee) are fine. We get a "Sending Confirm" page printed after the aborted fax. It says "Mode: ECM" and "Result: Send Error."

You have to go into the settings on the fax machine. There will be an option for a prefix number. Someone put a 9 in there. Having the 9 in there will make it dial a 9 then the number you are trying to faxt too. Remove the 9.
You can turn the sounds of the HP Fax (including ringing) on and off using the control
panel button. You can also set all sounds to turn off on a daily schedule; for example, turn
all the sounds off between 8 pm and 8 am.
1. Press Menu repeatedly until BASIC FAX appears and press OK.
2. Silent Mode will display. Press OK.
3. Select On-Daily and press OK.
From: 00h To: 23h will display.
4. Enter a start time and an end time and press OK.
Unfortunately wer purchased two new hp office jet 7610 which do not come with cabling and we could not get the fax to work. I spent 3 days on the telephone with hp and British Telecom each of which blamed it on each other. After doing some research on the internet I discovered that hp require a strange cable formant which is called a 'cross-over cable' is required. I bought them from cabling4less.co.uk and the product code is BT-203X. They can be found on their web site www.cabling4less.co.uk The link is: http://www.cabling4less.co.uk/category.php?cat_id=237 This should resolve this frustrating problem.
once you dial the number you fax will automatically start sending the the Fax signal which sounds like short beeps. This is done so the receivers phone (when answered) will recognized the beeps and switch to fax receive mode. If you are getting the recording that you mentioned above, that means the number you dialed was not successful in making the connection. Once you dial the number you should hear the phone ringing followed by some churping noises when the other end answers the call... then other churping and gargle like sounds initially as the fax proceeds.
sounds like your are having trouble with the number you are dialing.
Hope this helps..
You cannot use a four wire cable to connect the fax to the wall. You must use a two wire cable, like the one that came with the machine. BTW, that means you can't you the EXT port to connect a two line phone or answering machine.
I had been confused for the past ten months on this issue and just figured it out! Get a distinctive ring from you telephone service. If you have a answering machine, set it to answer on the 4th ring. On the fax, press menue til you get to the BASIC FAX, press OK, scroll the arrow button til you get to the DISTINCTIVE RING, press OK. Call your special fax number assigned from the telephone co, the machine should read DRPD OK, then on the face of the hp640 on the left i believe is a button called Rcv. Mode/Contrast, press that til you get to DRPD Mode, press OK. It should work great!! Hope this helps.
