<div dir="ltr">Hi Rolf,<br><br>I tested scanimage with different options today. In particular, I tested all the combinations of connection/resolution/color available with flatbed mode:<br><br><div> --Connection: usb/net<br> --Resolution: 75/150/300/600/1200<br> --Color: color/gray/lineart<br><br><div>...for a total of 30 tests. I can confirm that all the combinations work, I have a folder with all the scans and a script, so I can replicate the operation while collecting debug info by setting SANE_DEBUG_PIXMA if necessary, and share all the results somewhere (eg. Google Drive). <br><br>But ADF _do not_ work for me using scanimage or scanadf.

<p>Hi Patrick,</p>
<p>Please scan all scan options (color, grayscale, lineart, 75...600
dpi) from flatbed. <br>
</p>
<p>Then test the document feeder with your preferred settings (e.g.
A4, 300 dpi) and the whole sheet size. With a single sheet and
multiple sheets. At least test duplex scanning from ADF, single
sheet and multiple sheets. <br>
</p>
<p>I'm getting the best ADF scan results with gscan2pdf (I really
never got best results using scanimage or xsane). For scanning
single sheets from flatbed or ADF (one side only) you can use your
favorite frontend, e.g. xsane.<br>
</p>
<p>If you might have problems, please test also connected with USB
only.</p>
<p>Many thanks for report.</p>
<p>Cheers,<br>
Rolf<br>

My reference to ScanGearMP is simply for completeness, but does
not relate with the main point of my previous mail.<br>
<br>
So, rephrasing: "I can say LibSane works with MB2350 via LAN
connection".</div>

<div dir="ltr">Hello, <br>
I saw testers are needed for this series of scanners. <br>
<br>
I have a Canon Maxify MB2350 scanner, connected through
LAN.
<div>I can detect the scanner from Canon ScanGearMP 3.40
from Ubuntu Linux 16.04. <br>
</div>
<div>I added "bjnp://<a href="http://192.168.1.5" target="_blank">192.168.1.5</a>"
to my pixma.conf file, where 192.168.1.5 is my scanner IP
address.<br>
LibSane is taken from the daily git snapshots from
RolfBensch's PPA (now: 1.0.27+git20180122).<br>
<br>
<u>I can say it works.</u> But I hope to help more if I
can. So: is there a way to do something useful other than
scanning a random sheet of paper? Do you have standard
tests or data collection procedure that could help you to
improve support or verify that all is working great? Do
you need some packet sniffing or something like that?<br>
<br>
Best regards,<br>
Patrick Roncagliolo<br>
