Assembled Wisdom!

I am sure that this question has a simple answer.  My situation:
I bought a Canon imageCLASS MF4770n all-in-one
printer(scanner/copier/fax) on Friday.  It took me a while to get
my CUPS and lpadmin commands so that it would print, but thanks
to the documentation provided by Canon to Linux users, it now
prints just fine.  I would like it to scan also, and I'm having
trouble.  I think my "sane back end" is not configured properly.

I have run  sane-find-scanner  and my result is:
  found USB scanner (vendor=0x04a9 [Canon Inc], product=0x2774
  [MF4700 Series]) at libusb:001:004
However, scanimage -L  reports: "No scanners were identified. . . ."
So something is awry.

As confirmation, I have checked  http://www.sane-project.org/  for
Supported devices and my all-in-one given above is indeed on that

I have simple-scan installed, but when run it can't find the scanner.

I am running Debian Wheezy.

Thanks in advance for anticipated assistance!
