You were right.  I tried a new shell but I hadn't tried logging back 
in.  When I logged out and back in, the new group was recognized and the 
scanner was available.

That means the entry in:

/etc/udev/rules/60-libsane.rules

is:

SYSFS{idVendor}=="04a9", SYSFS{idProduct}=="220e", 
SYMLINK+="scanner-%k",  GROUP="scanner", MODE="0660"

Thanks for your response.
