Printer Wake Up

[lowtimer]

My HP Laser M479fdw printer is connected to my shared voice phone line, voice and fax work as expected.  The problem I have is when I pick up my phone to place a phone call, the printer wakes up.  The printer will remain awake the entire time the phone is used.  A minute after the phone is hung up, the printer will go back to asleep.  To ensure there wasn't some type of interference, I unplugged the printer from the wall jack.  As expected with the phone line disconnected, the printer doesn't wake up.  I've looked through the settings and turned off auto answer, but nothing seems to prevent the printer from waking up while using the phone.  I have an older HP printer/fax that doesn't wake up while using the phone.  The older printer will only wakeup if there is an incoming call as I expected the new HP printer to have the same behavior.

I know fax and landlines are becoming a thing of the past, but does any one have a printer that wakes up by simply taking the phone off the hook?

Appreciate the help, thanks.

Hello @lowtimer ,
Welcome to the HP Support Community!

If you have connected the phone and fax line to the printer, then the printer is responding correctly as you described.
It is best if the telephone and fax cables are connected directly to a router with 2 analog ports.

Then this effect does not occur.

Hope this helps! Keep me posted.
