As the MF4770 is a laser device it most likely does NOT use the bjnp
protocol but the mfnp protocol. This is supported only in the git
version of sane.
It requires opening port 8610 outgoing and 8612 incoming (see man
sane-pixma, section about firewalling).  If the scanner and the computer
are one the same subnet, opening these ports should be sufficient for
auto-detection of the scanner. I don't have a laser multi-functional but
have developed the mfnp support with one user that has a MF4880. That
works. Another user got it to work with a MF4570.

If you opened the firewall and it did not work, please get me a logfile
from scanimage -L with
export SANE_DEBUG_BJNP=4 
set. You may also want to try setting
mfnp://192.168.1.51 
in pixma.conf
