Hello,
I have an old Mustek Paragon MFS-600CX (3-pass) which worked great
for years with SuSE Linux 5.0-6.1 and sane. Now I stupidly decided
to upgrade (i.e. new install) to SuSE Linux 7.0 which comes with
kernel 2.2.16 and sane 1.0.2.
Since doing so, I have the following scanner/scsi/sane? problem.
Monochrome scanning works with scanimage and xscanimage, but
if I try to do a color scan with xscanimage, all thee scanpasses
seem to be performed normally, but after the last pass xscanimage
hangs. However, if I look in the output file the scan seems to
be okay. If I use the Gimp-plugin, the situation is even worse:
The (monochrome) preview does not work properly eighter and
the scanner sled stops sometimes somewhere on the scanarea.
A few times I had also a problem described in the PROBLEMS file which
came with sane: The scansled exceeded the physical scanarea, which
resulted in a awful noise.
I think I can remember, that the scannersled performed a slight
'twitch' in its park position after finishing the last scanpass.
(I know, that this is not a scientific precise statement but I
don't know to desribe it better). This is not performed any more
since I installed the new Linux version.
Up to now, I used the scanner with the primitive NCR53c400 controller
which was shipped with it. When I found some timeout warings from
this card in the logfiles, I suspected some low-level SCSI problem
with the new kernel and repaced the card by an Adaptec AHA-1510.
But this changed noting on the behaviour of the scanner.
So the problem seems to be eihter in the higher level SCSI drivers or
somewhere in sane. If anybody ever observed this problem or
has some hints where the problem is or how it can be located I would
be very grateful.
I know, one solution would be to throw away the scanner and buy a
new one, but sice it has been serving me for years and it has a
larger scanarea compared to the new models I still like it and would
be very happy if it would be possible to convince it to
work again properly.
Thanks in advance for any suggestions, comments, hints ...
Georg
