Can't fax in or out with my L7680

Cannot send faxes
Check the fax number, connection setup, and settings when faxes do not send.
Perform the following tasks in the order given. Test fax transmission after each task to see if the issue is resolved. You can send a test fax to the HP Fax Test Service at 1-888-HPFaxme (1-888-473-2963). This free service sends a return fax within 5 to 7 minutes when fax is working properly. Your fax number must match the number you entered in the fax header to receive the return fax.
Print a fax test report
Run a fax test from the printer control panel to identify issues with the printer, phone line connection, or fax settings.
On the printer control panel, select Run Fax Test or Fax Test Report in the Fax or Setup menu.
Review the report for any tests that failed and follow any instructions to resolve the issue.
Redial the number and change settings
To increase the chance of a successful fax transmission, send the fax again after adjusting settings.
Fax settings are in the Fax or Setup menus on the printer control panel.
Manually redial the fax number: Make sure you include any outside access code, such as '9', the long-distance country code, and the area code. If you are using speed dial, make sure the saved number has the required dashes between numbers.
Lower the fax speed: Using the slow or standard setting can improve sending success.
Turn on Error Correction Mode: If Error Correction Mode is off, turn it on to increase the chance of a successful transmission. The fax might take longer to complete.
Send the fax in black and white: The receiving fax machine might not support color faxes.
Confirm the dialing type (tone or pulse): Most phone lines use tone dialing.
Enable error reporting: The Fax Error Reports feature prints a report if an error occurs. If the error includes a numeric error code, go to HP Customer Support, and then search for the error code.
Check the fax connection
Check the phone line for issues.
Call the fax number from a phone: If you do not hear fax tones, the receiving fax machine might be turned off or disconnected.
Confirm the fax cords are in the correct ports: The phone line should be connected to the 1-LINE port and an answering machine or phone should be connected to the 2-EXT port on the back of the printer.
Connect a phone to the wall jack and try to make a call: If the call fails or there is no dial tone, check if another phone or device is keeping the line open. If you hear static, there might be interference from nearby electrical appliances, such as motors, fans, or televisions, or from coax cables. There might also be an issue with the line quality that requires attention from your phone service provider.
Use the fax cord that shipped with your printer: HP fax-capable printers ship with a two-wire phone cord. If you are using a different cord, confirm the connector does not have four wires. Shorter, higher quality cords work better than longer cords of lesser quality.
Example of a phone cord with two wires
Remove other devices from the phone line: Devices such as answering machines, modems, or other telephones might cause faxing issues.
Reset the printer
Reset the printer to recover from printer errors or failures.
If your printer has a rechargeable battery, remove it.
With the printer turned on, disconnect the power cord from the printer.
Unplug the power cord from the power source.
Wait 60 seconds.
Reconnect the power cord to a wall outlet and to the printer.
NOTE: HP recommends plugging the printer directly into a wall outlet.
Turn on the printer to complete the reset.
