cannot get fax machine to work on HP Office Jet Pro 6978

[Kimanne1]

We have installed the printer/fax as instructed.  We have 2 phone lines.  One for the home phone and one for the new fax. They are both going into the Modem for Time Warner Cable (as instructed to do). The HP helpdesk said we need a filter, so we bought one.  Time warner said they have never heard of anyone needing a filter and all we have to do is plug the line into the instructed outlet (which we also did). We have purchased 3 different things to get this to work. Still the error when running a fax test is "An active phone line was not detected." Any suggestions???

Welcome to HP forums, I see that you need assistance in setting up the fax on your printer.

• Call the fax number you are sending to from a phone: If you do not hear fax tones, the receiving fax machine might be turned off or disconnected.

• Confirm the fax setup: There are two phone ports on the rear the printer labeled 1-Line and 2-Ext. Connect the phone line to the 1-Line port, and connect the answering machine to 2-Ext.

• Check the phone line: 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. Additionally, if you hear static, there might be interference from nearby electrical appliances (motors, fans, kitchen appliances, or televisions) and/or coax cables, or there is 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.

  

• Remove other devices from the phone line: Devices such as answering machines, modems, or other telephones might cause faxing issues.
