Fax function on HP OfficeJet 3830 All-In-One Printer

[Davcon33]

I thought I had everything set up as directed but when I tried to reach the Fax test 888 number it seems to connect with the receiving fax unit through a quick Handshake sound but then goes silent. After a while I get the message 345 and notice that the fax was not sent

A warm welcome to HP Support Community!

Disabling ECM(Error correction Mode) and lowering the Fax speed may resolve the issue. Let's try these step's:

1.) From the Home screen, touch Fax .

2.) Touch Setup .

3.) Touch Preferences.

4.) Scroll to Error Correction Mode and touch Off.

5.) Try to Fax.

Once we turn off ECM, the Fax Speed is automatically set to Medium.

If issue persists, try the steps available in this document. 

Let me know how it goes!
