I have a HP 5510 all in one series copy/fax/scanner/printer and it all goes thru my regular phone line so its not on its own line.

I have a task that requires me to go to a website and fax documents to myself because I cannot print from the site directly.

This takes several hours to do, so is there a way to change my settings somewhere so that my fax is default as prime over the phone?
For example take my phone out of the equation and when I'm done I can switch it back to phone prime? I'm not worried about missing calls because what I am doing now is getting up to hit the fax/start button every time that it rings, nobody would get thru anyway.

I tried setting the fax machine itself to auto answer at one ring... that didn't work. Any other suggestions out there? Any help would be much appreciated ~
