Error "scanimage: sane_start: Scanner cover is open"

[Lars]

Hallo,

since I updated from Kubuntu 6.06 to 7.10 running an "SHARP JX330 SCSI
flatbed scanner" with scanimage produces this error:

$ scanimage --device-name='sharp:/dev/sg0' --source='Flatbed'>out.pnm
scanimage: sane_start: Scanner cover is open

Because I try to scan a book, the scanner cover is open indeed, but this
used to be no problem.

If I scan with xscanimage, it finally works with open cover if I scan
with closed cover first. Here the output of
SANE_DEBUG_XSCANIMAGE=4 xscanimage 2>debug.log

Without the dummy scan with cover closed:
[xscanimage] scan_start
[xscanimage] get_resolution
[xscanimage] scan_dialog: finished #No scanning but error message as described above

Unfortunately this workaround doesn't work with gscan2pdf.
I also tried to find a hardware workaround but I don't know how the scanner knows it is open. I thought there would be a little stylus or switch that has to be pressed, but the one I found doesn't work. I have no manual or technical information about the scanner.

Thanks,
Lars

Is this symptom still reproducible in 8.10?
