Distinctive Ring settings on LaserJet PRO MFP 281fdw

[mrcanada976]

How do I set the number of rings for distinctive ring on this printer.  I have checked the settings and it shows :

Distinctive Ring:  All rings

But I cannot modify this to double or triple ring.

As it is set to 

Rings to answer: 1

This means it will completely take over my phone line.  I only want it to answer on the distinctive ring.

I also cannot modify the phone number and company tag used by the fax machine feature of the printer.  I have tried using the touch pad as well as the HP Smart and HP wizard.

This befuddles me it is a very basic setting

If this device is network attached, simply type the printer's IP address into the address bar of your browser to access the embedded web server. You can make changes that way. The ability to change some features from the control panel can be disabled so that might be what is happening and of course it is always possible that there is a password set on the machine.

Ive already tried that.  There is nowhere to change the setting for anything, even the fax number
