<div>Hi,<br>
<br>
</div>
I used this link, now I have 1.0.24 backend installed, and it
got worse: original problem remained, but now I got this:<br>
<br>
aszabo@mepc:/tmp$ scanimage --format=tiff --mode=Color
--resolution 300 > a.tiff<br>
scanimage: unrecognized option '--format=tiff'<br>
<br>
aszabo@mepc:/tmp$ scanimage -V<br>
scanimage (sane-backends) 1.0.22; backend version 1.0.24<br>
<br>
</div>
<div>I would start from the fact that this scanner did work well
for a year or so (even with this old backend), then all of a
sudden it started misbehaving. Question is what caused it?<br>
</div>

Thx, Dolfy<br>

Hello,<br>
<br>
I think the version you use was compiled without tiff support.
Don't use the --format option, then you'll have a pnm file that you
will be able to transform to tiff (with ppm2tiff for instance).
Check you can scan several pages, to see if SANE update fixes your
problem.<br>
Telling what went wrong is hard. It could be from kernel,
changing form libusb to libusb-1.0 to backend itself. Most probably
a libusb change is the cause, making the backend exhibit a bug.<br>
<br>

Hi Stef,<br>
<br>
<div class="im">
It is not so easy to install a newer version as Ubuntu
12.04 comes with 1.0.22 and there are tons of
dependencies too. Can you please identify what went
wrong with the current version? Earlier scanning went
smoothly, then after a regular software update it
stopped working well. I believe it was because of a
kernel upgrade, but cannot tell for sure.<br>
<br>
Thx<br>

Hello,<br>
<br>
1.0.22 is old. Many fixes for the genesys backend were
part of 1.0.23 release. They are outlined in
Changelog-1.0.23 (in SANE's source tree). And they are quite
numerous.<br>
You may consider compile it by yourself if you are
afraid of the dependencies. But I would be surprised that
they are that much dependencies, and in this mailing list
Rolf Bensch announced last month a PPA tracking current
source code:<br>
<br>

href="https://launchpad.net/%7Erolfbensch/+archive/sane-git"
target="_blank">https://launchpad.net/~rolfbensch/+archive/sane-git</a><br>
<br>
I'm sure you can find something to install that doesn't pull
in that many changes.<br>
<br>
Regards,<br>
Stef<br>
