The scanner is slow in preview mode and makes a different noise
(probably because it is doing very small y steps). Right now
the preview mode is not the same as the normal 200 dpi mode.
But this is not surprising: Somewhere around line 870 in snapscan-scsi.c
you inform the scanner that it is in preview mode:
source = 0x0;
if (pss->preview) {
source |= 0x80; /* no high quality in preview */
}
else {
source |= 0x40; /* no preview */
}
I suspect that the scanner takes that as an excuse to get lazy
(with respect to the y motion). :-)
I will download the latest CVS version during the weekend and
see if the problem still persists.
