[SOLVED] Scanner do not work on Arch but on Mint

Hello,

I have following problem:
I have an old scanner (Canon CanoScan 4400f) which works on Linux Mint without problems with sane, sane-utils and simple-scan.  It doesn't work on Arch, and I don't know why.
I followd the instructions in =https://wiki.archlinux.org/title/SANE]SANE and installed sane & ipp-usb and started ipp-usb (I use the scanner via usb). After I rebooted  and opened simple-scan, the scanner was not detected. After switching off and on again, reinstalling etc. I compiled sane directly from the AUR. The result was the same as before: The scanner was not recognized. Since the scanner was already older I also tried lib32-sane, but that didn't help either.

Can someone help me and tell me why it doesn't work on Arch but works on Mint????

Supposingly supported through http://www.sane-project.org/man/sane-genesys.5.html
I doubt that airscan/ipp-usb will work, so get rid of that, restart saned and check scanimage -L

Can someone help me and tell me why it doesn't work on Arch but works on Mint?

How (through which protocol/driver) did you access the scanner in Mint?

Re: [SOLVED] Scanner do not work on Arch but on Mint

So I have now uninstalled ipp-usb and sane-airscane and restarted. When I ran scanimage -L I got the following message:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

After that I tried sane-find-scanner. (I loaded the scsi module with modprobe sg)
Result:

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.

could not fetch string descriptor: Pipe error
could not fetch string descriptor: Pipe error
found USB scanner (vendor=0x04a9 [Canon], product=0x2228 [CanoScan], chip=GL843) at libusb:001:005
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

The scanner is recognized, but when I use scanimage -L it does not work.
On Linux Mint the whole thing works out-of-the-box. When I run scanimage -L there I get the following feedback:

device `genesys:libusb:002:003' is a Canon Canoscan 4400f flatbed scanner

Any other ideas on how I can fix the problem? Thanks.

Please use code tags for shell IO and file contents, https://bbs.archlinux.org/help.php#bbcode
Probably rights issue, try "sudo scanimage -L" and see https://wiki.archlinux.org/title/SANE#P … on_problem

Physical damage due to overheating reported. Enable in genesys.conf at your own risk. See https://gitlab.com/sane-project/backends/-/issues/436.

Can you check if the scanner is enabled in /etc/sane.d/genesys.conf in Linux Mint but disabled in Arch?

I have tried everything with and without sudo. Still does not work. (And sorry, forgot the code tags.)

Thank you very much! That was the problem. Now my scanner also works under Arch. Excellent!

Great. Just make sure to also read the linked GitLab issue, your scanner apparently was disabled for a reason (e.g. stay away from the transparency mode).
