Can't get the Fax Machine to SEND a fax

Hooked up the fax the other day and it will receive a fax but I can't get it to send one. It dials the number and after a few rings it drops the call. I tried the HP help desk and was on the phone for over an hour but they couldn't resolve the problem. Any ideas?

Re: Can't get the Fax Machine to SEND a fax

Check to make sure that "mode" is correct. "Auto Receive", and/or, "fax" mode (not printer, etc.,)

  1. Make sure the fax machine is plugged into a power source and also plugged into a working phone jack.
  2. Turn the fax machine on.
  3. Obtain the fax number of the destination fax machine.
  4. Gather the documents you want to send and put them in the order you want them to be received.
  5. Fill out a separate piece of paper called a coversheet with the recipient's name, fax number/phone number, your name, your phone number, a short message and number of pages (including coversheet).
  6. Lay the documents face-up in the fax machine feeder tray with the coversheet on top
  7. Dial the recipient's fax number - put 9 before the number and area code
  8. Press the "fax" or "send" button, depending on the particular fax machine model

Please inform how to send a fax

well, I don't see your fax machine model, but typically...

  1. Place document to send in the input tray (usually top loader)
  2. Enter telephone number for receiving facsimile machine. If you are in an office, you may have to prefix the number with an 8 or 9, then country code. IE 9-1-555-555-5555.
  3. Then press Send (usually a green button).
  4. If it will not send, make sure you have dial tone. There is usually a handset on the facsimile machine which you can pick up to hear the dial tone.

I don't understand the one touch dialing on the HP 2140

Hi Suzeo. Many HP fax machines have the function you are requesting. It is called the broadcast fax feature. Look in your owner manual for this feature. If I knew which model you have I would have researched it for you. IF by chance, your machine does not have this feature, it would be money well spent to replace your current machine with one that does. Depending on how many pages the daily fax is, I am estimating that you are spending an hour or more each day on this task. J.

Never send a fax how do i do it?

Assuming the fax machine is properly hooked up...

Put the paper in the scan slot facing the right way (usually with the print away from you).

Dial the number, then click OK or SEND. The fax machine should do the rest.

Cannot receive a fax but can send one out

Make sure your phone lin is plugged in the jack on the machine that says LINE not the jack that says TEL or PHONE. I have seen this before. the unit gets a dial tone and can send but will not answer.
Hope this helps

Fax will only send and not receive

Call your fax machine from a regular phone and listen for fax tones. Sender may be dialing the wrong number. Is your phone line DSL?

Cannot receive faxes, but can send

I can send faxes from my HP Fax 1010, but cannot receive them. I can dial the number from another phone but it will keep ringing and the machine never picks up. We have tested the phone line and all seems well. Is there some setting on the fax machine itself that I need to change in order to receive? Any assistance you can provide would be greatly appreciated.
