Actually, I installed 1.0.0 first, then 1.0.1 thinking
maybe it was fixed in the newer version, then 0.71 because
I saw a report of someone getting this exact scanner to
work with that version.

# ldd /usr/local/bin/scanimage
libsane.so.1 => /usr/local/lib/libsane.so.1 (0x40000000)
libdl.so.2 => /lib/libdl.so.2 (0x40008000)
libnsl.so.1 => /lib/libnsl.so.1 (0x4000d000)
libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0x40013000)
libm.so.6 => /lib/libm.so.6 (0x40031000)
libc.so.6 => /lib/libc.so.6 (0x4004a000)
/lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x2aaaa000)

I assume libsane-umax is the back-end that you are refering to?

lrwxrwxrwx 1 root root 21 May 19 13:27 libsane-umax.so -> libsane-umax.so.1.0.1
lrwxrwxrwx 1 root root 21 May 19 13:27 libsane-umax.so.1 -> libsane-umax.so.1.0.1
-rwxr-xr-x 1 root root 234000 May 19 13:27 libsane-umax.so.1.0.1

I've deleted the other libsane-umax versions to make sure they
weren't being used instead.

I'm not familar with the sane code. Is there a particular place
I should be looking to debug the pixels/scanline problem?

Mark.
