Samsung Xpress MFP SL-M2070FW - Fax Printer Does Not Have a Dial Tone

If your fax printer does not have a dial tone, do the following:
  • Make sure the phone line is connected properly to the fax printer's phone connection on the back of the unit.
  • Make sure the phone line connected to the fax printer is working and getting a dial tone by texting it with a phone.
If the problem persists, go to HP Support.
