- The 1200SP (1.02) does not need the line distance fix, so you should
run configure with the corresponding option.

- You should set SG_BIG_BUF to 128*1024-512 and recompile the kernel
(and sane!) to make it aware of the change.

- from my experience with this device the scan area is set correctly
by sane, but under certain conditions which I could not reproduce, the
scanner in fact starts a scan without resetting.

Bye,
