Make sure you are plugged into the LINE port and you are not sharing the phone line with a computer.

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.
Hope It's resolve all Your Printer Problem,

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.

I keep getting a 'Phone off the hook' message. Phone is not off the hook


Hi,

Disconnect the power cord from back of the printer ( while printer is power on )
While holding the # and 6 key connect the cord back
( This step will erase all the fax logs and settings you have set on the printer )

Also
Press the Setup button and Scroll to FAX SETTINGS ( or ADVANCED FAX SETTINGS )
Check for ECM ( Error correction mode ) - Press OK
Turn it OFF

Finally if the issue is still not resolved,
Disconnect the Phone cord from Printer port and re-connect
Check for any other loose connections ( of phone socket ) within the house. ( disconnect and reconnect )

The Error message should go off

My HP 7780 always says phone off hook. When I disconnect the phone line for awhile and reinstall it faxes once properly then the phone off hook message reappears.


I use a VOIP line and get the same error msg. Here's what I do- I dial the fax number with the line unplugged (hence no off-hook message), press "start Fax", and as soon as I hear the fax machine "Click" to pickup the line, I put the line in the machine. Works every time!

I finally figured mine out. It definitely has to do with the fax function as I could do everything except fax. Mine was the phone being off the hook (looking at the back off the printer the little phone symbol) even though the phone line coming into the machine was unplugged (L symbol on the back of the printer). Hopefully yours will be as easy.

Phone off hook means to say that the printer is connected to a fax line and the fax line is in use. That message won't disappear until you disconnect the phone cable on the printer or no one is using the line for fax.

Will not fax


Hook a phone to the fax line and try to dial out... a fax line is no different than a phone line at your house ,, don't use a multi line phone like the ones at the office use a phone like you would have at the house to hook the the fax line .. If you are able to dial out call someone and check the line for static and pops they can cause the fax not to work either.. Good Luck
