Roger,
I went live with AC first week of Nov 2011, (and much thanks to David's recommendation dictated notes as initial entry a week before visit)but noticed that I went through more paper than I have ever done in 18 years of practice, until I started using Updox about the first week of January 2012. After about 2 weeks the paper trail started falling off considerably and the scanning fell off as well. Once my nurse got comfortable with no paper the tendency to file paper diminished significantly to essentially nil. I only have a simple operation 2 exam rooms and one nurse that does everything--scheduling, filing, patient care. But the front office handles the billing side of things.
So I suspect once you integrate the Updox a bit longer things will change for the better--my nurse absolutely loves the updox because of the incoming /outgoing electronic faxing/messaging efficiency along with the patient portals--maybe this doesn't apply to you with the MFC fax machine--hope this helps--jimmie
