Hi Karol99,
Thank you for using the Support Forum. Have you adjusted the ring tone volume in the as noted in step 7 for the solution for configuring the fax settings? If this does not help you can use an external phone so that you can hear incoming fax calls. Please consider contacting your support centre for further assistance.
I recently purchased a WorkCentre 3615 to replace a 3220. I assumed that the much more expensive machine would at a minimum contain the same utilities and driver features as the dated 3220. After spending a long time on the phone with a tech, he told me that the 3615 have a loudspeaker but is not useful for incoming fax ring. I didn't want to belive in it. I tried to set it in Icoming Defaults for FAX in Properties but no metter what I changed (Recive Mode:Ans/FAX Mode;TEL/FAX Mode or FAX Mode and Ring Tone Volume: form off to MAX), it wasn't working. Solution from technician was to reach out to the company that sold me the machine and send it back. I did it. Now I recived a new one and have exactly the same problem.Unbelievable.
Interesting fact:
When I set the tone volume directly on the printer, then the loudspeaker rings (for try). After that i make a test-fax-call and it gives any sound.
Have you some solution for me? Thanks in advance.
