Hi,
I've uninstalled ippusbxd, then reboot... and as a result the scanner
is not detected anymore!
'scanimage -L' returns "No scanners were identified."
can you give me the log of :
SANE_DEBUG_DLL=255 scanimage -L
your scanner is found :
found USB scanner (vendor=0x04a9 [Canon], product=0x1890 [TS8300
series]) at libusb:003:009
'sane-find-scanner' still lists the scanner among the USB devices
(output of 'sudo sane-find-scanner -v -v' is attached).
I don't understand you point regarding the scanner being plugged in
USB. Do you mean it would better to have it connected through Wifi ?

Yoann

Hi,
Thanks for the answer. Indeed, things are better with libsane 1.0.31.
However, I still encounter some random errors when trying to use the
scanner. For instance, using 'scanimage', I get:
yoann@yoann-desktop:~$ scanimage -d escl:http://127.0.0.1:60000 >
outfile.pnm
Output format is not set, using pnm as a default.
Erreur de segmentation (core dumped)
yoann@yoann-desktop:~$ scanimage -d escl:http://127.0.0.1:60000 >
outfile.pnm
Output format is not set, using pnm as a default.
scanimage: rounded value of br-x from 215.9 to 215.9
scanimage: rounded value of br-y from 297.011 to 297.011
scanimage: sane_start: Device busy
yoann@yoann-desktop:~$ scanimage -d escl:http://127.0.0.1:60000 >
outfile.pnm
Output format is not set, using pnm as a default.

... the first 3 attempts failed, the fourth one succeed. The number
of
attempts may change from one trial to another. And the scanner is
almost unusable from a graphical frontend such as XSane (probably
because of these errors I guess).
You are plugged in USB!
Why use the network driver?
ippusbxd doesn't work very well, I advise you to uninstall it.
# sudo apt purge ippusbxd
The PIXMA driver should then detect your scanner and everything should
work.
You can also use it in networks!

If there is any manipulation that I should try to provide more
information, please let me know.

Hi,
I've a brand new PIxma TS8350 scanner, that is -- unfortunately --
not
recognized by SANE. I've seen on the device list page that testers
are
needed for this device, so I would be happy to test what need to
be
tested in order to have this thing work properly.
Please find attached the output of command 'sudo sane-find-scanner
-v -v'.
The usb support has been added, for your template in version 1.0.30
of sane-backends.
Full wifi support in version 1.0.31 of sane-backends.
If your OS is ubuntu I invite you to update as follows:
sudo add-apt-repository ppa:sane-project/sane-git
sudo apt update
sudo apt install libsane libsane-common sane-utils
Regards,
Y.
