Re: [sane-devel] Need Help getting Canon ImageClass MF244dw working

[Curtis Graham]

I still can't seem to get my scanner to work with debian 1.0.25-4.1. I'm
guessing I need to get up to 1.0.27. My Multi Scanner is a Canon imageclass
MF244dw. Here is the output:

sudo sane-find-scanner

 # 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.

I think it is
usb 0x04a9 0x27d2

sudo scanimage -L

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).

Any help with pointing me in the right direction would be much appreciated.

Thank You
Curtis

The printing function is working with gutenprint. If only scanning too

Could anyone tell me if it's possible to tweak up support for this
printer? I can provide logs for anything needed. It's a simple flatbed
usb scanner on a multifunction printer.

usb 0x04a9 0x1795
Normalement c'est le backend pixma que vous devez utiliser.
Par conséquent la ligne doit seulement être ajouter dans pixma.conf
Regarder dans /etc/sane.d/dll.conf
#pixma
remplacer par
pixma

Re: [sane-devel] sane-backend 1.0.27 USB broken on Mac with Homebrew

[schmo-fu]

Okay, here i go again ...

i can confirm, that it is not a permission problem. It's just that there
are no files, where they should be.

The scanner is recognized by sane-find-scanner now. But scanimage -L
doesn't find it, because the sane-backends .conf files are supposed to
be at:
/usr/local/Cellar/sane-backends/1.0.27_1/etc/sane.d/
but there is no etc/ (and there also is no doc/; both are present under
1.0.25_1; (»officially« there should also be a tools/, but this isn't
present neither in 25 nor in 27).

Looking at
https://gist.github.com/anonymous/5e324f6e1c7c8b9ea4172a72e0352255
[[see note]]
the make-log shows, that the backends are all build with
"-DPATH_SANE_CONFIG_DIR=usr/local/Cellar/sane-backends/1.0.27_2/etc/sane.d"
which seems alright.

Maybe they get deleted later? I don't know enough about this process, to
know where to look for answers.
@Yurii can you help with this?


Greetings,
Thomas.S

[[ Note:
I corrected and reintroduced the patch from 1.0.25, that fixes some
header files, and thus made a version 1.0.27_2. ]]
