It might be that this is specific to the driver from Brother (brscan-0.2.1-0.i386.deb) for the MFC3420C. I recently did some tests with a Canon LiDE30 (plustek-backend shipped with SANE) and JSane worked fine. Also another problem I have with the MFC3420C (see http://lists.alioth.debian.org/pipermail/sane-devel/2006-July/017297.html) did not occur with the LiDE30. best Jens Jens Gulden schrieb: > Hello Andi, > > nice work.
