On my C7 box, simple-scan requires libsane. try: ldd simple-scan |grep -i sane.
# ldd /usr/bin/simple-scan | grep -i sane
libsane.so.1 => /lib64/libsane.so.1 (0x00007f3668291000)
ldd doesn't show any other sane dependencies, but I'd sorta think
that simple-scan would also need sane-backends as well. Here's all
the sane things I have installed, FYI:
# ldd /usr/bin/simple-scan | grep -i sane
libsane.so.1 => /lib64/libsane.so.1 (0x00007f3668291000)
[root@fcshome log]# yum list installed | grep -i sane

also FYI, I'm using a Canon LiDE 210, which works fine for me.
Good luck!
