Andrey, That is a pretty nice image for no calibration. It should clean up after calibration.
Maybe Stef can figure out why calibration is failing. I think there are some settings in genesys.c and genesys_gl841.c that might need to be tweeked. As Stef suggested, you could also try cloning the Pentax DS Mobile 600 settings. It uses slightly different motor and sensor settings.
