Hi Jack,
Here you will find the packages for your distribution : 
https://build.opensuse.org/package/binaries/home:thierry1970/sane-backends/Raspbian_10
They are not the latest versions but they support your hardware.
you need to get :
#$ wget 
https://build.opensuse.org/package/binary/download/home:thierry1970/sane-backends/Raspbian_10/armv7l/libsane-common_1.0.32+20210417-0_all.deb
#$ wget 
https://build.opensuse.org/package/binary/download/home:thierry1970/sane-backends/Raspbian_10/armv7l/libsane1_1.0.32+20210417-0_armhf.deb
#$ wget

#$ sudo apt update
#$ sudo apt install ./libsane-common_1.0.32+20210417-0_all.deb
