[sane-devel] Canon IX-4015 not working

Fri Jul 13 12:44:39 UTC 2012

Hello,
I've found an old Canon IX-4015 scanner:
scsi2 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 7.0
        <Adaptec 2940 SCSI adapter>
        aic7870: Single Channel A, SCSI Id=7, 16/253 SCBs
scsi 2:0:2:0: Scanner           CANON    IX-4015          3.03 PQ: 0 ANSI: 2
scsi target2:0:2: Beginning Domain Validation
scsi target2:0:2: Ending Domain Validation
scsi 2:0:2:0: Attached scsi generic sg3 type 6

sane-find-scanner is happy:
found SCSI scanner "CANON IX-4015 3.03" at /dev/sg3

But scanimage seems not be so happy - the first run after scanner power cycle 
crashes:
$ scanimage -L
Segmentation fault
$ scanimage -L
device `canon:/dev/sg3' is a CANON IX-4015          flatbed scanner

And even after that, scanimage does not work:
$ scanimage >/dev/null
scanimage: sane_start: Operation not supported

Old canon backend web says:
"IX-4015: you have to make a simple modification in the backend sources, then 
it seems to work. See the archived mailing list for details. The modification 
will be included in the next backend release."
(http://home.rzg.mpg.de/~mpd/sane/index-old.html)

I wonder if that "next release" with modification was ever made. I also 
haven't found the details in the mailing list archive, only some old posts 
about IX-4015 docs:
http://www.sane-project.org/old-archive/1998-07/0042.html

Can someone provide me the IX-4015 documentation and/or some (old) code?
