Harri, to see if your device is supported at all, please check first
using a USB connection. The network protocol piggybacks on the USB
backend. so a test of the USB interface should show if the MF8380 is
supported in the Sane version you are using.
I am not sure if this covers your device, but the MF8300 Series has
been added quite some time ago (May 2015?). So your sane version may be
too old. You may need to upgrae to 1.0.27.

You can also try:
SANE_DEBUG_PIXMA=21 scanimage 2> log and forward the log file.
