plustek: Thread: problems with epson perfection 1260 and 1.0.15

Hello.  I've been running sane (1.0.7) from Debian stable for a long time
and recently upgraded to sarge, which contains 1.0.15 of libsane.
Fortunately I never ran at a high resolution with the old version and it
worked well.  Since I've upgraded I've had a couple of problems.  One is
that as the scanner runs, I can hear what sound like pauses and the
resulting scan is missing small slices.  See this photo for an example:
http://maui.doit.org/~dmartin/scanned-with-sane.jpg

Also when the scan has completed and the scanner is driving the CCD back
into its parked position it's making a fairly loud "clunk" at the end that
it did not used to.

I was a little concerned that the old driver had messed the stepper motor
up (the timing seemed pretty suspect though, coinciding exactly with the
software upgrade!) so I grabbed another (commercial) app's trial version to
make sure it wasn't the scanner.  Here is the scan from that:
http://maui.doit.org/~dmartin/scanned-with-vuescan.jpg

No horizontal lines...  Any known issues with this combination?  Should I
file a bug report either with Debian or somewhere else?  Let me know if any
additional info is needed.

Thanks,
	Dale

on thursday last week, I got a similary report from another guy. I'm working
on that and hopefully I'm able to submit a patch before christmas.

If you have the chance, please downgrade to the earlier 1.0.14 version and try
again.

Ciao,
Gerhard

Thanks for the reply, Gerhard!  Adrian Bunk's "-2" backport collection[1] has
1.0.14 in it.  I installed that, and it's working fine again.  Thanks for
the tip, and the forthcoming patch!  If you need a guinea pig I'm happy to
apply and test a patch on the 1.0.15 Debian package.

Take care,
     Dale
