[sane-devel] HP 2200c problems, wrong colors and stripes.

[Fabiano]

I have a problem since about 2 years just after a Linux update (first it was working right in Linux).
The scanner is working fine in windows XP, scanned images are perfect; In Linux, the first scan is (sometimes) right than the other scans 
are corrupted, the images have vertical stripes (both in colour and grey scans). The colour scans results in wrong colors and sometimes the 
scan looks more light in the left side and darker in the right side
I'm currently using Opensuse 12.1 (but the problem was still present in 11.2/3), xsane version 0.998, sane backends 1.0.22, ibusb 0.1.13.
This is my sane-find-scanner and scanimage -L output:

   # sane-find-scanner will now attempt to detect your scanner. If the
   # result is different from what you expected, first make sure your
   # scanner is powered up and properly connected to your computer.

   # No SCSI scanners found. If you expected something different, make sure that
   # you have loaded a kernel SCSI driver for your SCSI adapter.

scanimage -L
device `plustek:libusb:002:003' is a Hewlett-Packard Scanjet 2200c flatbed scanner

I have also tried to disable "speedup-sensor" by xsane option but it hasn't changes.
Have you any suggestion, may I provide further information in order to track the problem?
I really love my HP scanner and I hope to find out a solution.

Thanks in advance
