F9: Scanning with canon lide-30 (USB) produces awful noises

[Joachim Backes]

Hi,

my scanner is an USB scanner, Canon Lide-30. Since some weeks, sometimes 
when scanning, the scanner produces awful noises during scan (like a 
saw), and the scanner input is unusable.

rpm -qa '*sane*'
libsane-hpaio-2.8.2-2.fc9.i386
xsane-0.995-3.fc9.i386
xsane-gimp-0.995-3.fc9.i386
sane-backends-1.0.19-10.fc9.i386
sane-backends-libs-1.0.19-10.fc9.i386

Does somebody have similar problems?

I think this is a software problem, because I never have this behaviour 
in WinXP.

I found some entries in the Ubuntu forums, but no solution.

Regards

Joachim Backes

I've had something similar, but my scanner is old, and the toothed belt
that drives the sled up and down isn't as flexible as it used to be.  If
I pull the belt out of the mechanism, it doesn't spring back into a
circular shape, it stays in a long thin loop, as if it were still
wrapped around the cogs.  Sometimes it does skip some teeth the first
time I use it after it's sat untouched for weeks, or months.

Tim,

thanks for your answer, but, again, I think it's a software problem 
because I have no problems under WinXP.
