Hello,
you are doing the right thing. From the stretched pictures we can see
it
is a sensor issue, not a motor one. You might try to evaluate these other
sensors: CCD_ROADWARRIOR, CCD_XP300, CCD_DP685.
For calibration and size issues, a scanimage logfile would be great,
something like:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL841=255
scanimage -d genesys --calibrate 2>calibrate.log >out.pnm
and for length issue:
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL841=255
scanimage -d genesys --mode Color 2>rl.log >rl.pnm
For debugging purpose I have this script which runs from compiled
binaries without needing to install. i.e I run 'make' then this script in the
backend subdirectory, which saves me time (I change backend option depending
on what I'm testing):
#!/bin/bash
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL646=255
export SANE_DEBUG_GENESYS_GL841=255
export SANE_DEBUG_GENESYS_GL843=255
export SANE_DEBUG_GENESYS_GL847=255
export SANE_DEBUG_GENESYS_GL124=255
export LD_PRELOAD=.libs/libsane-genesys.so
../frontend/scanimage -d genesys --resolution 150 --height 30 --mode Color
2>rl.log >rl.pnm
Regards,
Stef
