I ran the following test (as "root" immediately after system start):

# setup environment for debugging
export SANE_DEBUG_GENESYS=255
export SANE_DEBUG_GENESYS_LOW=255
export SANE_DEBUG_GENESYS_GL124=255

# get system log before scanning
journalctl -x -e >journalctl_output_before_scan.txt

# calibrate scanner and do a preview
scanimage --clear-calibration --preview --mode Color 1>calibrate.pnm
2>calibrate.log 

# get system log after scanning
journalctl -x -e >journalctl_output_after_scan.txt

<<< ... <<<

The file calibrate.pnm is empty. No other .pnm files were produced.

Find the following files attached:

journalctl_output_before_scan.txt
calibrate.log
