The error message I received was 007. If this is your error message.... then keep reading. The error message relates to the power from the fax machine. Look at the line cord from the fax machine. The little plastic end should show 2 metal connectors for the wires. If yours shows 4 as mine did, it's as simple as changing to a 2 wire cord. You could call Vonage and they will ask you if yours is a 2 or 4 wire, but if you don't know what to look for..... since the wires and connectors are the same size, you might think yours is 2 when it's 4 as I did. Good luck!

All fax machines are ANALOG devices. They are designed to work on POTS (Plain Old Telephone System). Any other condition is a **** shoot.

FAX MACHINE WILL NOT WORK WITH MAGIC JACK


Magic Jack will work with fax machines. You may have to experiment by slowing down the fax machines modem transmits speed. This is done in the machines menu.

The Magic Jack manual is quite clear, it can handle faxing.

HP 640 fax won't send fax but phone works


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.

We can send faxes but we can not receive faxes. The fax machine that sends the fax tell it that our line is busy. Is that a machine problem or a phone line problem?


Problem lies in your Receive Mode setting. If you don't have a dedicated phone line for the fax machine, you need to set it up for either Manual where you answer every call or Fax/Tel whereby the Fax machine determines if the incoming call is a fax or phone call. Instructions per Intellifax 4100 Manual.

Select a Receive Mode
Choose the mode that best suits your needs by pressing the Mode button
repeatedly until the FAX and FAX/TEL lights show the setting you want to use.
Manual
You must answer every call yourself.
The Brother machine must be started manually
to receive faxes.
Fax
For use with a dedicated fax line.
Every call is answered as a fax.
Fax/Tel
For receiving fax and voice calls on one line.
The FAX answers every call and receives a fax or
double rings for you to pick up a voice call.
TAD
For use with an answering device.
The TAD answers every call and stores voice messages.
Fax messages are printed.

HP640 not receiving with Distinctive Ring Option


You need a dedicated ANALOG phone line.

A DSL filter screens out ANALOG signals to a DSL device.not the other way around. There are no DIGITAL fax machines.

I have the HP640 Fax machine and I'm trying to program the distinctive ring mode but when I follow the instruction which state to press the menu button and scroll to advanced fax and press ok and then it...


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.
