CM2320nf no dial tone (can't send fax)

[LarrySchwarcz]

Hi,

I'm trying to test the fax function in my used-but-new-to-me CM2320nf but it doesn't send faxes yet.

I'm thinking that it's not getting dial tone since I'm used to hearing a dial tone with fax machines. 

My process is:

• Put paper to fax on glass
• Press, "Start Fax" button
• Dial phone number

I can hear the tones as I dial and it then has the "beep" sound it makes once it would normally connect but I don't hear any dial tone or ringing.

I tried plugging an ordinary telephone into the telephone plug on the back and I get dial tone there so I'm thinking that the phone jack and cable are OK.

I ran the Fax Test and put the report at the end of this posting. I did try changing the "Detect Dial Tone" to, "On" but that didn't make any difference. 

Any suggestions on where to start to diagnois this issue?

Thanks in advance!
Larry.

UPDATE: I just had my brother try to send me a fax and the machine didn't seem to react to the call at all and my brother said he got a busy signal (odd since I can call it on a voice line).

Hi Biswajeet,

Thank you for your reply! In this case I'm not using this product in a business environment. It's in my home and a used product (I didn't buy it new) so I didn't think it was approprate for me to submit an official  case with HP support and instead posted it here to the user community. 

Thanks!
Larry.

UPDATE: Issued fixed!

Turns out my CM2320nf was fine! I had it plugged into a VOIP line and the issue was with my phone line! I changed credit cards and forgot to update my VOIP provider. Once I got the phone line working again it now works fine!

And, just a word of warning, don't have two fax machines on the same phone line turned on. This also caused issues for me. I would try to send a fax over the phone line but my other fax machine was inteferring with it.

Thanks!

Larry.
