Is this over USB as well? If so, it the backend proper. You may want to
talk to Rolf again for that

Read the source code... NO there was no documentation whatsoever. I
reverse engineered the protocol from PCAP traces from the Windows
driver. But that is only part of the story: the bjnp protocol just
translates the USB protocol to run over TCP/IP. So the actual
processing is still done by the same backend code as used for USB
scanning. Internally in the bjnp code I map the sanner name to the USB-
id as that is used a lot in the backend...
I reverse engineered the protocol using the MP970 I had at that time,
and it still works for recent scanners that use BJNP, even though I
have seen some variations used by Canon (later Windows drivers for the
scanner use more TCP and less UDP. But that may also have been the case
with the BJNP printing part. And if it works, don't touch it...

Regarding ADF support, I can tell you a difference between two situations:

ADF empty: backend hangs a while, than I can read "scanimage: sane_read:
Document feeder out of documents"
ADF with sheets loaded: operation hats instantaneously, and I can read
"scanimage: sane_read: Operation was cancelled"

I can send you some files (scanimage logs and wireshark dumps) if you want.

Re: [sane-devel] How can I help with Canon Maxify MB2000 series testing?

2018-03-17 Thread Patrick Roncagliolo

I have empty iptables.
By reading manpages, I found that /etc/sane.d was not in
the $SANE_CONFIG_DIR.
I put there "bjnp://192.168.1.5", lanched scanimage -L and it finally
worked.

One question/curiosity: scangearmp2 (Canon proprietary scan tool for linux)
sends a discovery probe on port 8611 instead of 8612, and behaves
differently from the pixma backend. Is there some reverse-engineered
documentation about the BJNP messages, types, codes? I imagine so, given
that pixma-backend exists, but I had no success in finding it.

I have an MB5050  myself and that works pretty well.
Can you please (in a shell) do:

export SANE_DEBUG_BJNP=20
scanimage -L 2>  log

and mail the resulting log file?
Some of the most recent Canon scanners no longer support bjnp, butthe
MB2000 is as far as I know of the same generation as my MB5050, so I
expect bjnp till to be supported.

Please check your firewall settings (see man sane-pixma) to be sure
that traffic does not get blocked. There should be no reason to modify
the pixma.conf file, unless you are on WIFI: ome users report problems
oer WIFI.
See the bjnp-timeout settings in pixma.conf. A single line of 
bjnp-timeout=5000 
at the beginning of that file should in that case do the trick.
I decided against including that by default as it would cause long
delays for user using other backends

Hi,

I tested pixma version 0.17.46 thru USB. It works.

However, after updating from your PPa, I'm not able to discover my printer
on the network. pixma.conf seems to be ignored, no matter if I set the IP
and multiple port combinations (8610, 8611, 8612, but whit wireshark I see
only requests as broadcast on ports 8610 8612). What could have been
changed? Any hints about some dumb things that I can have forgotten since

Re: [sane-devel] How can I help with Canon Maxify MB2000 series testing?

2018-03-11 Thread Rolf Bensch

Hi Patrick,

I just added button support for your scanner.

If you're fetching the sources from git you can start testing now.
Otherwise you must wait 'til tomorrow to get the update from my ppa.

Button support is basicly implemented in standard frontends. You should
use gscan2pdf to get best results. Or if you're familiar programming
bash scripts, you can use scanbd
(https://sourceforge.net/projects/scanbd/). If you like I can provide my
pixma scripts.

Hope this helps.

Cheers,
Rolf

Hi Patrick,

Many thanks for the log file.

I found some differences to the implemented settings. For comparison
please send a logfile from a normal flatbed scan.

Cheers,
Rolf

Hi Patrick,

Here you can find further infos:
https://wiki.wireshark.org/CaptureSetup/USB

You need to connect your scanner via USB and disconnect Ethernet|WiFi.

Hope this helps.

Re: [sane-devel] How can I help with Canon Maxify MB2000 series testing?

2018-02-04 Thread Rolf Bensch

Hi Louis,

Please try to fix this issue. The main problem are special needed
settings in function send_scan_param() (command 0xde20) from
pixma_mp150.c. You can fetch correct settings from reference scans from
a Windows machine.

To check button support, you can use this simple test:

1. push any button

2. $ SANE_DEBUG_PIXMA=11 scanimage -A

If you scanner has button support, you should get a similar response:

[...]
  Buttons:
    --button-update
    Update button state
[pixma] INTR T=1.165 len=32
[pixma]  :00 20 00 00 00 00 00 00  00 00 00 00 00 00 00 00
[pixma]  0010:00 00 00 00 00 00 00 00  00 00 00 00 00 00 00 00
[pixma]
    --button-1  [1] [read-only]
    Button 1
    --button-2  [0] [read-only]
    Button 2
    --original  [0] [read-only]
    Type of original to scan
    --target  [2] [read-only]
    Target operation type
    --scan-resolution  [0] [read-only]
    Scan resolution
[...]

Important are existing lines starting with [pixma]. With this info it's
simple to enable button support.

Hope this helps.

Cheers,
Rolf

Hi Rolf,

Can you point to a short guide for getting proper USB logfiles?

Meanwhile, I noticed that wireshark do not have full support for BJNP. I
browsed SANE and CUPS sources, and the BJNP dissector, and maybe in my
spare time I'd like to improve the dissector. If you have any unofficial
doc or article/analysis about BJNP outside what's already in C sources, I'd
like to get some links.

2018-02-04 Thread Rolf Bensch

Hi Patrick,

It seems that we have a general problem with ADF scanning from all
Maxify scanners.

If possible, please provide USB logfiles from a Windows machine scanning
from ADF and duplex ADF, one page and two pages, using Wireshark. Then I
can try to fix this.

In the meantime I'll update the doc files.

Many thanks for your help.

Cheers,
Rolf

Hi Patrick
Buttons can be used in xsane (button controlled scan option in standard
options), but are more relevant with scanbd (scan button daemon). It
did not work with my MB5050 but I scan so seldom that I never got
around fixing the isues I found when I started adaption of the pixma
backend.

2018-01-29 Thread Patrick Roncagliolo

Yes, --button-controlled=yes has no effect on the scanner: nothing happens,
scanimage just hangs while the scanner seems to not have understood the
command, the display do not change page nor shows a prompt or some sign
that an operation is pending. I do not know if this feature should be
supported on the MB2350, I never saw such a feature even on Windows when
configuring/using my scanner. Could you tell me where to check if MB2350
supports the button-controlled mode or if you know some windows software
that can show me how it works so that I can understand what should be the
expected behaviour on Linux, if any?

This sounds the same as the status on my MB5050. You may also want to
test the button support: that probably does not work either.

Re: [sane-devel] How can I help with Canon Maxify MB2000 series testing?

2018-01-28 Thread Patrick Roncagliolo

Hi Rolf,

I tested scanimage with different options today. In particular, I tested
all the combinations of connection/resolution/color available with flatbed
mode:

 --Connection: usb/net
 --Resolution: 75/150/300/600/1200
 --Color: color/gray/lineart

...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).

But ADF _do not_ work for me using scanimage or scanadf. Here's a sample
output (SANE_DEBUG_PIXMA=3 PIXMA_EXPERIMENT=1):

[pixma] pixma is compiled with pthread support.

2018-01-27 Thread Rolf Bensch

Hi Patrick,

Please scan all scan options (color, grayscale, lineart, 75...600 dpi)
from flatbed.

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.

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.

If you might have problems, please test also connected with USB only.

Many thanks for report.

Cheers,
Rolf

I forgot to specify that obviously SANE driver worked and allowed me to do
some scans with Xsane and ScanImage.
My reference to ScanGearMP is simply for completeness, but does not relate
with the main point of my previous mail.

So, rephrasing:  "I can say LibSane works with MB2350 via LAN connection".

[sane-devel] How can I help with Canon Maxify MB2000 series testing?

2018-01-25 Thread Patrick Roncagliolo

Hello,
I saw testers are needed for this series of scanners.

I have a Canon Maxify MB2350 scanner, connected through LAN.
I can detect the scanner from Canon ScanGearMP 3.40 from Ubuntu Linux
16.04.
I added "bjnp://192.168.1.5" to my pixma.conf file, where 192.168.1.5 is my
scanner IP address.
LibSane is taken from the daily git snapshots from RolfBensch's PPA (now:
1.0.27+git20180122).

*I can say it works.* 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?

Best regards,
Patrick Roncagliolo
