HP 610 message Phone off Hook

The store is no longer supported for WP7 handsets like the Lumia 610. There is no solution apart from getting another phone.

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 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 had this same problem. I changed the phone cord to a 2 conductor DSL phone cord. Problem solved. Try it. It should work for you.

dont worry
just install it in ur pc and just setup all setting to its default

It is a default message when you are calling from the same phone as your fax machine.
If yourAll-In-One is sharing a phone line with your telephone, modem, or another device, and if any of the other devices is using the line, you will see the "Phone off hook" message on the All-In-One front panel. You can still print, copy, and scan with the All-In-One when you see this message, but you cannot send or receive faxes. To clear the message, check each device to make sure that it is no longer using the line.

sounds like a bad power supply or hvt, have it checked out, can be dangerous
