Either do

export SANE_DEBUG_FUJITSU=255
scanimage ...

or

SANE_DEBUG_FUJITSU=255 scanimage ...

At least if you use bash as your shell.

Maybe you can show us some parts of the source code if such a problem
arises in future. At least I don't understand for what you need fopen
without further information and why using it should influence
sane_start/sane_read.
