Interesting. I'm going to test with our S510 later today. What I remember is that the S510 was always quite slow. We even have an S300 (which is not really a Fujitsu scanner) and it is much faster than the S510. I remember the -B option, but wasn't there something to be careful about it? I will of course also try it but IIRC there is something about it, maybe not all backends work well with it? I will try 1.0.20, 1.0.21 and current GIT to see if there is a difference. Simon
