I don't know how many details you already discover. However i searched for "error" and "fail" in sane_P.log (created by "scanimage --clear-calibration --preview --mode Color 1>calibrate.pnm 2>sane_P.log 3>sane_P_err.log") and found: === error === [14:50:47.426435] [genesys] sane_genesys_read: got error: could not stop motor : Error during device I/O === fail === [14:50:30.088182] [genesys] genesys::MotorSlopeTable genesys::create_slope_table(const genesys::MotorSlope&, unsigned int, genesys::StepType, unsigned int, unsigned int, unsigned int): failed to reach target speed [14:50:31.429674] [genesys] genesys::MotorSlopeTable genesys::create_slope_table(const genesys::MotorSlope&, unsigned int, genesys::StepType, unsigned int, unsigned int, unsigned int): failed to reach target speed [14:50:33.923249] [genesys] genesys::MotorSlopeTable genesys::create_slope_table(const genesys::MotorSlope&, unsigned int, genesys::StepType, unsigned int, unsigned int, unsigned int): failed to reach target speed [14:50:34.237580] [genesys] genesys::MotorSlopeTable genesys::create_slope_table(const genesys::MotorSlope&, unsigned int, genesys::StepType, unsigned int, unsigned int, unsigned int): failed to reach target speed [14:50:37.036257] [genesys] genesys::MotorSlopeTable genesys::create_slope_table(const genesys::MotorSlope&, unsigned int, genesys::StepType, unsigned int, unsigned int, unsigned int): failed to reach target speed [14:50:37.343190] [genesys] genesys::MotorSlopeTable genesys::create_slope_table(const genesys::MotorSlope&, unsigned int, genesys::StepType, unsigned int, unsigned int, unsigned int): failed to reach target speed [14:50:46.244840] [genesys] genesys::MotorSlopeTable genesys::create_slope_table(const genesys::MotorSlope&, unsigned int, genesys::StepType, unsigned int, unsigned int, unsigned int): failed to reach target speed [14:50:47.426256] [genesys] void genesys::scanner_stop_action(genesys::Genesys_Device&): failed [14:50:47.426344] [genesys] void genesys::scanner_move(genesys::Genesys_Device&, genesys::ScanMethod, unsigned int, genesys::Direction): failed [14:50:47.426377] [genesys] void genesys::scanner_move_back_home(genesys::Genesys_Device&, bool): failed [14:50:47.426405] [genesys] void genesys::sane_read_impl(SANE_Handle, SANE_Byte*, SANE_Int, SANE_Int*): failed [14:50:48.543828] [genesys] void genesys::scanner_stop_action(genesys::Genesys_Device&): failed [14:50:48.543913] [genesys] virtual void genesys::gl847::CommandSetGl847::end_scan(genesys::Genesys_Device*, genesys::Genesys_Register_Set*, bool) const: failed [14:50:48.543944] [genesys] void genesys::sane_cancel_impl(SANE_Handle): failed Hope it helps to get this fixed soon.
