Why my HP 640 Fax will not receive a fax?


Your firstly need to put your hp fax machine through the machines fax diagnostics found under the tools menu. This will hopefully identify any obvious problems.
You need to ensure that you have the correct cable from your telephone socket to the fax machine. It should be a BT Plug to RJ11 Crossover telephone cable in the U.K. This cable reverses the polarity of the terminals and will look identical to other terminals but is not.
Available from cabling for less Item Code BT-203X Price 3.28 plus vat and postage.
Ask your telephone line provider to check there is no noise in the background as fax machines sender and fax machiine receiver are like birds in love. They sing to each other before the receiving machine recognises the sending machine and accepts the message.
If you require any further assistance then please do not hesitate to contact me.

I can not receive a fax


Hi there, Fax machines are still in common use today despite the widespread adoption of computers along with their multiple communication tools, including e-mail and social networks. Fax problems can include trouble receiving faxes, dialing issues, faxes not printing and poor print quality. Performing periodic maintenance can help with fax problems. Check any visual indicators for trouble. Many fax machines have a display panel and use it for reporting error messages. Often the messages are in plain text and can be understood without referring to the instruction book. Refer to your fax machine'smag-glass_10x10.gif instruction manual for any numeric error codes.
  • Step 2.Replace the cables. In particular, replace the telephone line cable that runs from the wall to the fax machine. The plugs can become lame, and the wire itself can break inside, providing no visual indication it's broken.

    I can receive faxes but cannot send them


    Check your fax speed settings, also, make sure you get a good clear dial tone on the line. Sometimes it wont send if it detects line noise.

    I have an HP Officejet v series printer, fax, amd copier. It will send a fax, but it is not received. Someone can send me a faz, it sends, but I don't receive it.


    Verify that the sender has the correct fax number.

    Call your fax machine from a regular phone and listen for fax tones.

    Fax machines are ANALOG devices. Make sure your fax machine is not connected to DSL or any other digital phone line.

    1)Disconnect the power cord from the rear of the HP Fax machine.
    2)Verify that the phone cable is fully inserted into the fax machine. If your model has a removable Line Interface Unit (LIU) where the phone line plugs into, verify that it is securely snapped in place.
    3)If the HP Fax model belongs to the HP Officejet R80 Series , verify that the cable which goes from the Automatic Document Feeder assembly to the rear of the HP All-in-One base is connected.
    4)Reconnect the power cord.After the fax reinitializes and it is ready, try to send and receive faxes again.

    This problem could be Phone line problem, or hardware failure or receiver's (the machine of the person whom you are sending the fax) machine problem and so on. First, let's check the line, if you have another Phone line, please dial from the number to your number, also, connect the currently connected line to a receiver and call a Land-line number, if the outgoing or incoming is ok, the proceed forward, otherwise, you telephone operator should check the line.


    Sometimes, sending fax to a particular number doesn't work, to make sure, try sending a fax to another number.

    If the line which is connected to the machine is extended from another machine such as Receiver, Switch, etc... unplug them and connect the fax machine directly to the Line.

    It's also important to adjust the compatibility mode, to do this, follow the steps below:
    • Press Menu.
    • Press the up or down arrow key to select Fax.
    • Press OK.
    • Press the up or down arrow key to select Miscellaneous.
    • Press OK.
    • Press the up or down arrow key to select Compatibility.
    • Press the left or right arrow key to select Basic (for VoIP).
    • Press OK.
    • Press Stop/Exit.

    If you place the scanning document/file on the auto-sheet feeder, you can help it pulling inside the passage or you can use the glass (flatbed) instead. Sometimes, this small mistakes with the sheet-feeder creates this problem. You can also clean the rollers inside the ADF (auto document feeder) passage.

    If all of the above measure don't help, I would suggest you to call brother and seek their help. The rest is with mechanical or we can say hardware or firmware related issue. (use this form to contact Brother)

    I wish you good luck.

    Thanks for using FixYa.

    Can't receive fax but can send


    Call your cell phone from the fax machine and check the caller ID to make sure that it is the correct number for your fax machine. Next, call the fax machine from you cell phone, and make sure the fax machine rings. Problems like these are almost always a phone line issue, not the machine.
