[sane-devel] Sending confirmation about the pixma backend

[Rogério Brito]

Dear people,

I just (yesterday night) bought myself a Canon PIXMA E4210 that I want to
use *purely* with Free Software.

In my limited hours with it, I found that the scanning wasn't working with
the programs in Debian testing nor sid but that I could make it work with an
USB cable if I installed sane-backends 1.0.28 (I actually grabbed a package
uploaded to mentors.debian.org).

Since I read the code and it mentioned that it needed testers, here is a
report.  With the newer version of sane-backends, I can scan from the
flatbed, as expected, and it works as well as I could expect (minus the
fragility of this piece of hardware---disappointed with that, but that's not
software-related, of course).

Unfortunately, I can't scan from the ADF (which was one of the main reasons
for me to choose this printer instead of others--with money being a 2nd
factor, of course).

This is what I have in my dmesg logs:

- - - - - - - - - - - - - - - - - - - - - -

[ 9138.284573] usbcore: registered new interface driver usblp
- - - - - - - - - - - - - - - - - - - - - -

With scanimage, this is what I get:

- - - - - - - - - - - - - - - - - - - - - -
$ scanimage -L
device `pixma:04A91855_103CD1' is a CANON Canon PIXMA E4200 Series 
multi-function peripheral
- - - - - - - - - - - - - - - - - - - - - -

Making sure that there is a paper in the flatbed:

- - - - - - - - - - - - - - - - - - - - - -
$ time scanimage --device=pixma:04A91855_103CD1 --progress --mode=Lineart 
--resolution=600 --format=png --gamma=1 > out.png
Progress: 100.0%
real0m21.907s
user0m1.375s
sys 0m0.323s
$ file out.png
out.png: PNG image data, 5104 x 7016, 1-bit grayscale, non-interlaced
- - - - - - - - - - - - - - - - - - - - - -

Now, making sure that there are sheets of paper on the ADF:

- - - - - - - - - - - - - - - - - - - - - -
$ scanadf -d pixma:04A91855_103CD1 --mode Lineart --gamma 1 --output-file 
foo%02d.pnm
Scanned document foo01.pnm
scanadf: sane_read: Error during device I/O
Error during device I/O
Scanned 1 pages
- - - - - - - - - - - - - - - - - - - - - -

What was scanned is the page from the flatbed, not from the ADF.

If, OTOH, I specify something like:

- - - - - - - - - - - - - - - - - - - - - -
$ scanadf -d pixma:04A91855_103CD1 --mode Lineart --gamma 1 --source "Automatic 
Document Feeder" --output-file foo%02d.pbm
scanadf: sane_read: Document feeder out of documents
Scanned 0 pages
- - - - - - - - - - - - - - - - - - - - - -

The printer doesn't do anything, nothing moves etc.  The ADF works if I tell
it to scan from my Android device (but, then, the Canon app doesn't allow me
to specify resolution, nor if I want B/W images etc.---yes, it's that
limited).

So, in essence, there is partial success with the pixma backend and this
device. If there is anything that I can answer before I return this device
(unfortunately, I'm not really sure that I can return it, but I will try
it), then, please let me know and I will test whatever is desired.

In the case of it being possible to return this device and get something
else in its place, which manufacturer/model would be preferred to have
*full* functionality with Free Software only? Any recommendations?



Thanks,

Rogério Brito.

I've applied the patch in PR !200.

Thank you!

Maybe the scanner just does not work fully and thus was never included
into the scanner list as a supported one. We can add it as unsupported
though.

Hi,

It seems that the network model differs between sources and network
scanner discovery. I just fixed it. It will be available from my ppa
tomorrow.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] sane-pixma Canon MF269dw

[Rolf Bensch]

Hi Vilnius,

The behavior of xsane sounds strange. Please check what's going on with:
$ SANE_DEBUG_PIXMA=11 SANE_DEBUG_BJNP=5 xsane

Alternatively you can try a test scan with:
$ SANE_DEBUG_PIXMA=11 SANE_DEBUG_BJNP=5 scanimage >test.pnm

If you want to scan from ADF, for a first approach you should use
gscan2pdf (ADF implementation in xsane and scanimage is very tricky to use):
$ SANE_DEBUG_PIXMA=11 SANE_DEBUG_BJNP=5 gscan2pdf

If you have further problems, please send me compressed log files.

If ADF still isn't working, please also create an USB snoop file from a
Windows machine as reference. You can use wireshark with usbpcap
(https://wiki.wireshark.org/CaptureSetup/USB).

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon MG3050

[Rolf Bensch]

Hello,

I just updated the doc files.

@Louis: Maybe it's possible to fix not working WiFi?

Many thanks for your help.

Cheers,
Rolf

 Hello Louis,
 scanner and client are in the same home network, there is no firewall

 I removed the last numbers from the IP manually. Sorry, if this leads

 confusion.

 Printing over wifi is working without any problems.

 I can scan over another device with a separate sane scan server
 (sane-utils) in my local network. But a direct link over wifi with
 this
 device seems impossible:

 /etc/sane.d/pixma.conf contains one line ... auto detection could not

I just updated the doc files.

Can you scan again after closing the message and/or does your scanner hang?

The pause comes from adf-wait parameter. Please read the man page for
details.

Please read 'man sane-pixma' to get some help for this issue. If this
won't help, please provide a log file with SANE_DEBUG_BJNP.

Many thanks for your report.

Hope this helps.

Re: [sane-devel] Canon TS8000 series PIXMA

[Rolf Bensch]

Hi Martin,

You're using an ancient version of SANE. Please update SANE and test again.

In the log you should see at least pixma version 0.23.3.

Hope this helps.

Cheers,
Rolf

 Hi Timothy,

 Many thanks for your report. I just updated the doc files.

 One last question: Have you also tried scanner access via WiFi? I
 suppose it's not working like other PIXMA TS scanners.

 Cheers,
 Rolf
