My M276nw can receive faxes but not send them.

Question

This was purchased to send faxes and of course it has stopped doing that less than a month after the warranty expired. 
I can't believe I was stupid enough to buy another HP product.  Never again.
There is no information on what to do.  It is always some sort of comm error.  Usually mapping back to to much noise on the line.  Problem with that is the receive is just fine.
Any suggestions?

Hi @OldLinuxGuy ,
I see that you are experiencing issues sending faxes, but you can receive faxes. I would like to help you.
Run a fax test.
From the Home screen, touch the wrench button.
Touch the service button.
Touch the Fax service button.
Touch run fax test.
You should get 4 passes.
Check these settings for the fax:
Go to the wrench icon/fax setup menu/advanced setup/private receive/turn it off.
Go to the wrench icon/service /fax service/error correction/turn it off.
Go to the wrench icon/fax setup /advanced setup/fax speed/change it to medium.
Go to wrench icon/service menu/fax service/clear saved faxes.
If you are still having issues, then follow this document.

Sorry for all the questions, but it will help to resolve this issue quicker.
Did the fax test pass?
What type of connection do you have? (Analogue, DSL, Cable Modem)
Are you using a filter?
Are you using the 2 wire fax cable?
Do you have distinctive ring set up on the line?
Is there any voice mail set up?
Do you have a answering machine? (Where is it connected to)
Where is the fax cable connected to? (modem, wall jack)
Is there a phone also connected the printer?
Have a nice day!
