Title:
pixma displays generic I/O error when scanner carriage is locked
Status in sane-backends package in Ubuntu:
Confirmed
Bug description:
trying to get a brand new Canon Canoscan 9000F Mark II working on my
father-in-law's Ubuntu 16.04.2 system.
'scanimage -L' works
'scanimage -T' returns an I/O error
I spent quite a while trying to debug an I/O error, trying different versions
of libsane etc.
even after I set various SANE_DEBUG env vars I still missed the text in the
response XML message, ScannerCarriageLockError.
I'm ~16,000km away from this scanner so I didn't notice my father-in-law
hadn't unlocked it after setting it up. Without setting SANE_DEBUG env vars
there's no way anyone is going to guess this from the output from scanimage.
Hoping to save the next poor soul some grief :)

looks good so far.
