Try plugging a phone, with a different cord, to the wall outlet the B640 is using. Do you hear a dial tone? If you do, replace the existing phone cord going to your B640. Now press the "hook" button on your B640. Do you hear a dial tone? If you answered yes, what messages are you seeing displayed now? Once I know your answer, we can take it from there.

Off the hook


A "Phone Off Hook" message is not an error. It simply indicates that a telephone receiver isoff the hook(the handset is lifted) and the telephone line is open. This message would be expected in the following situations:
  • A modem on the phone line is accessing the Internet.
  • A phone connected to the HP fax (or the same phone line) is using the line, or the handset has been lifted.
  • A credit card machine is using the phone line.
  • Another electronic device is using the phone line.
  • The Start Fax button was pressed with no telephone number entered. Pressing Stop or Cancel should return the display to a ready state.
When the other device is no longer using the phone line, the display should revert to the normal message.
Lets try the following,
Disconnect the phone cable from the back of the HP product and the message should clear. If the message does not clear, unplug the power cable from the back of the unit, wait 15 seconds, and then plug in the power cable.
if issue still exists try the followign
Disconnect the phone cable from the HP product and connect it to a single line phone. Pick up the handset and listen for a dial tone. If no dial tone is present, replace the phone cable. If a dial tone is still not present, a problem exists with the phone system.

Phone off hook message


A "Phone Off Hook" message is not an error. It simply indicates that a telephone receiver is off the hook (the handset is lifted) and the telephone line is open. This message would be expected in the following situations:
  • A modem on the phone line is accessing the Internet.
  • A phone connected to the HP fax (or the same phone line) is using the line, or the handset has been lifted.
  • A credit card machine is using the phone line.
  • Another electronic device is using the phone line.
  • The Start Fax button was pressed with no telephone number entered. Pressing Stop or Cancel should return the display to a ready state.
When the other device is no longer using the phone line, the display should revert to the normal message. Checking the phone line The most common reason for this message is when a dial-up modem is accessing the Internet on the same phone line. Just as two phone calls cannot come in at the same time, two devices cannot use the phone line at the same time. If a broadband modem (such as DSL or ISDN) is on the same phone line and the message appears all the time, please contact your Internet provider for assistance. Even if a dial tone is present when listening to the phone line, the HP product may detect the broadband data connection at the higher line frequencies. Broadband modems must have a line filter installed to work correctly. Contact the telephone company for assistance. Please follow the directions below to verify functionality.
  1. Verify that the phone cable going into the HP fax product from the wall jack is a two-conductor cable type, not four-conductor. A two-conductor cable, like the one that ships with the HP product, has two copper leads in the connector. The connectors are usually clear, making it possible to see how many copper leads are inside the cable. Replace a four-conductor cable with a two-conductor cable.
  2. Disconnect the phone cable from the back of the HP product and the message should clear. If the message does not clear, unplug the power cable from the back of the unit, wait 15 seconds, and then plug in the power cable. If the message persists, see the "Problem still exists" section below.
  3. Disconnect the phone cable from the HP product and connect it to a single line phone. Pick up the handset and listen for a dial tone. If no dial tone is present, replace the phone cable. If a dial tone is still not present, a problem exists with the phone system. Continue with the steps below if a dial tone is present.
  4. Plug the phone cable back into the HP product and hang up any phones with a lifted handset.
  5. Disconnect, one at a time, other phones and devices using the same phone line. Check the HP product display after disconnecting each phone or device. If the message clears after disconnecting a phone or device from the line, the problem is with that phone or device.
  6. If the message still exists after unplugging all other phones or devices, see the "Problem still exists" section below.
Problem still exists If the problem still exists after performing the steps above, the line interface unit (LIU), the part that the phone line plugs into, may be defective or the HP product may need to be serviced.

try contacting your telephone service provider asking is your line is allowed to fax .becoz some service providers block the fax line if it hasn't been using the fax for a long period of time.

Sending fax error message."Phone


No. Most of the time this "phone line error" can be caused by the telephone connection or issue on the phone line where the fax machine is connected.
Hope this will help.

My fax wont work in my ricoh aficio 1515 mf??


Using the 1515 as a fax machine is a pretty simple procedure if everything works right. All you have to do is hook a working phone line up to the phone jack on the back of the copier (the one labeled LINE, not TEL).

Why won't the fax work? If it is giving you an error message, what is the message?

If you are not getting a dial tone when faxing, unplug the fax from the phone line and plug a working phone in, and see if the phone gets a dial tone. If it doesn't, there is a problem with your phone line.

You can also try plugging the fax machine into another phone line. If the fax works on that line, then there may be a problem with the first line.

Are you having problems sending faxes or receiving them, or both?

Fax machine shows message "external phone". Machine is a Philips Magic 3 primo


The message means that a telephone connected to the machine is off hook. Either that or the internal relay that seizes the line after a phone is used has hung up. In that case, try removing the power to the machine and unplugging the line and any other phone cords connected to the machine. Then 1st plugging in the power cord and wait until the machine powers up. If the error code doesn't appear, then plug in the line cord.

Fax problem


unplug the fax from the phone line. call it from you cell.if you hear your phones ringing in the house, plug the fax machine back into the jack. [you should still be on your cell phone] if the line goes dead or stops ringing, there is a short with the fax machine or wire to the jack.if you hear a busy signal without the fax plugged in, unplug everything you have plugged into phone jacks thruout the house. call your # again.if you hear ringing on your cell phone, plug everything back in one at a time.[again while still on your cell phone] if it was one of the phones plugged into a jack, when you plug the shorted phone back into the jack, the line will go dead again. that phone or cord is the problem.
if still rings busy when everything is unplugged, then call your phone company. it can be an inside wire or jack problem, or the problem is outside your home.
hope this helps
