HP J3680, J3650 manual Display always shows Phone Off Hook

•Other equipment, which uses the same phone line as the device, might be causing the test to fail. To find out if other equipment is causing a problem, disconnect everything from the phone line, and then run the test again.

•If the Fax Line Condition Test passes without the other equipment, then one or more pieces of the equipment is causing problems; try adding them back one at a time and rerunning the test each time, until you identify which piece of equipment is causing the problem.

•If the Fax Line Condition Test fails without the other equipment, connect the device to a working phone line and continue reviewing the troubleshooting information in this section.

•If you are using a phone splitter, this can cause faxing problems. (A splitter is a two-cord connector that plugs into a telephone wall jack.) Try removing the splitter and connecting the device directly to the telephone wall jack.

•Make sure you use the phone cord that came with the device. If you do not use the supplied phone cord to connect from the telephone wall jack to the device, you might not be able to send or receive faxes. After you plug in the phone cord that came with the device, run the fax test again.

After you resolve any problems found, run the fax test again to make sure it passes and the device is ready for faxing. If the Fax Line Condition test continues to fail and you experience problems faxing, contact your telephone company and have them check the phone line.

Solution: You are using the wrong type of phone cord. Make sure you are using the phone cord that came with the device to connect the device to your phone line. If the phone cord that came with the device is not long enough, you can use a coupler to extend the length. You can purchase a coupler at an electronics store that carries phone accessories. You will also need another phone cord, which can be a standard phone cord that you might already have in your home or office.

Solution: Other equipment that uses the same phone line as the device might be in use. Make sure extension phones (phones on the same phone line, but not connected to the device) or other equipment are not in use or off the hook. For example, you cannot use the device for faxing if an extension phone is off the hook, or if you are using a computer dial-up modem to send e-mail or access the Internet.

The device is having problems sending and receiving faxes

Solution: Make sure the device is turned on. Look at the display on the device. If the display is blank and the Power light is not lit, the device is turned off. Make sure the power cord is firmly connected to the device and plugged into a power outlet.

Press the Power button to turn on the device.

After turning on the device, HP recommends you wait five minutes before sending or receiving a fax. The device cannot send or receive faxes while it is initializing after being turned on.
