Question about HP 640 Inkjet Fax Machine

1 Answer

Can't get this fax machine to work with my answering machine

I have an answering machine that is NOT connected to the fax machine. I am trying to figure out how to set the MODE/ RINGS TO ANSWER to work so that if a phone call comes in the answering machine will get it and if a fax comes in the fax machine will receive it. I can't get them to work at the same time.

    I have the same problem--just bought the machine. Did you ever figure it out? I thought that it may be because I have voice mail.

    I just bought the 640--I can't get the distinctive ring to work properly--I called HP and spoke with 4 different people and still can't get it to work right. Any ideas?

    I have the very same problem with an answering machine and the fax machine not being able to separate which should pick up. My answering machine is not hooked up to the fax machine either.

How do you get the fax machine to work?


First, make sure that the printer is connected to an active phone line. The best setup would be to connect the printer straight to a wall jack and the other end of the phone cable should be connected to the line port at the back of the printer.



For receiving faxes, check the fax settings > Ringing and Answering. Check if the Auto Answer is enabled and check how many rings the fax will pick up any faxes sent to your number. If you have an answering machine connected to the same line, set the printer to pick up 3 rings higher than your answering machine. If you have a voicemail service, you'll need to get a distinctive ring feature from your phone provider.


To get more information on how to setup the fax, check this manual: http://bit.ly/PCKt7z

No dial tone on phone connected to ext port on epson dx9400f


Buy a double adapter so both cords go to the LINE port. Set your answering machine to 6 or 7 rings so the fax picks up first. Your fax machine will know the difference between voice and fax calls,

>next set rings to answer on the fax machine higher than the answering machine...if your rings to answer on answering machine is 4 rings, set the fax to 6 rings...if it is a voice call the answering machine will pick it up at 4 rings then if it detects that it it a fax tone then it will transfer the call to fax.

My fax machine will send faxes but not receive them. I have made sure it is plugged in and connected but no faxes will come through. Please Help!


If you have an answering machine, have it answer at three rings. Have the fax answer at five rings. Let the answer machine go thru it's cycle, and see if the fax picks up.

How to set hp1040 fax to work with aout answering


Hi,

If you are using the same phone line as your fax, you can start by connecting the answering machine on Line2 or 2-Ext at the back of the fax. Set the fax to answer on two rings higher than the Answering Machine. (for example: if answering maching is 4 rings, fax is 6 rings)

And then, turn on the auto answer.

FAX, MODEL 920 NOT RECEIVING


Try calling your fax machine from a cell phone. If the fax doesen't answer, or if the line is busy, the phone line may be bad. Also check that the phone line to the fax is plugged into the receptical marked LINE, not PHONE. The PHONE receptical is to connect a telephone to the fax machine. If it still does not answer, try going into the fax menu and go to RECEIVE settngs. Try changing each setting, then call the fax with the cell to see if it answers. Write down each setting before you change it, so you can set it back if changing it does not solve the problem.

Still can't get fax not to pick up when answering machine is connected.


if you have the fax-575 there should be a TAD setting.

This is the setting you would use if you're using an answering machine on the same phone line as your fax machine.

To set the Recieve Mode :

Press Recieve Mode. The LCD display shows your current selection.

Continue to press Recieve Mode until your new selection appears. After 2 seconds the screen returns to the date and time display, along with your new Recieve Mode setting.


The 4 Recieve modes are Fax Only, Fax/Tel, TAD:Answering Machine, Manual.

Hope this helps!!!
