[sane-devel] Canon PIXMA MX725: ADF scan duplex and automatic recognition of number of pages

[Rolf Bensch]

Hi Timo,

First, we should enable your Ubuntu system to scan via flatbed, adf
simple and adf duplex. Sorry, I have no experiences scanning adf pages
from scanimage in batch mode. Therefore we should start using gsan2pdf.

Maybe somebody on the list can provide running scanimage batch mode
calls for pixma scanners using adf simple and adf duplex.

To make sure using the most recent version you should install SANE from
my ppa: https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git . OK,
you can stay using your self compiled version on Ubuntu, if you followed
the installation instructions from INSTALL.linux.

The ppa should also provide the recent SANE version for your rasp pi
(armhf or arm64; the packet manager should select the correct version).

OK, after installing (and removing a cruddy self compiled version: $
sudo make uninstall) the most recent version of SANE, you can create a
logfile on a console with, e.g.:

$ SANE_DEBUG_PIXMA=11 gscan2pdf &> pixma.log

On your raspberry pi (and Ubuntu) you can use this corresponding command
for scanimage:

$ SANE_DEBUG_PIXMA=11 scanimage [options] &> pixma.log

Maybe we need to debug and fix some issues on your Ubuntu machine first.

Second, if all scan types are running with gscan2pdf we can find a
working scanimage command which then can be simply adapted into your
raspberry pi.

Please provide the logfile of a failed scan in an archive, e.g. tar.gz,
zip or 7z.

Hope this helps.

Cheers,
Rolf

Hi Rolf,
thanks for your answer.
I am using scanimage on my raspberry pi without any GUI.
Now I tried scanning via my ubuntu desktop system, but the document is
just stopping in the ADF and the MX725 wants that I press OK to get
the document back. I already tried to reinstall sane and the pixma
backend (sane via apt-get remove and the pixma backend by checking out
via git and compiling again). Same result.
Is there maybe a way to debug my problem via console on the raspberry
pi, since the scanning there is working, just no ADF Duplex and batch
without providing the number of pages?
Best regards
Timo

Hi Timo,
I prefer gscan2pdf for multi page adf scans.
Please report if your problem also occurs with gscan2pdf.
Many thanks for your help.

Hi,
I got my MX725 running with scanimage on sane-pixma backend.
My last problems are that I can't scan in duplex mode via ADF and that
a ADF batch scan tries to scan another page after all pages are gone
from the ADF and then just gets stuck (need to use Ctrl + C once or
twice).
--ScanMode=Duplex => unrecognized option "--ScanMode"
--source="ADFDUP"
--source="Automatic Document Feeder(left align,duplex)
--source="Automatic Document Feeder(left align,Duplex)
and maybe some variations more => setting of option --source failed
(Invalid argument)
To scan "infinity pages, incrementing by 1, numbering from 1", I just
used --batch and scanned.
It's successfully scanning all the pages + tried to scan a next one
after the ADF runs out of pages to scan.
// Scanning page 1
// Scanned page 1. (scanner status = 5)
// Scanning page 2
Then nothing happens anymore. When I press Ctrl + C, it tries to
// scanimage: received signal 2
// scanimage: trying to stop scanner
Nothing happens, so I press Ctrl + C again
// scanimage: received signal 2
// scanimage: aborting
Scanning via --batch --batch-number=2 works fine, but I want to use
scanbuttond later so I don't want to set the number of pages every time.
I tried using --adf-wait=3 but this option is not recognized. It's not
listed in scanimage -A, but I found it in the online pixma-backend
documentation.
I hope, somebody can give a hint.
Thanks in advance
Timo

Hi,

I am using the sane libs (Ubuntu 16.04) with a Canon Pixma MX925
successfully for years now. Since some time (days, maybe weeks), the
scan process does not terminate well.

After scanning, or after acquiring a preview in Gimp using xscanimage,
the scan is read completely, but on the display of the device, the
german message "Dokument wird gescannt" (document is being scanned) is
remaining forever.

When trying to scan a second image, or after acquiring the preview
trying to scan the image for real, a timeout occurs.

Unplugging and replugging the USB resolves the situation, display on
scanner is emptied, scanadf (for example) can read the next image.

It looks like a "scan completed - reset" is not being sent at the end of
the scan process from the PC to the scanner.

All of this has worked well before, I did not change my setup, except
for applying all "ppa sane-git" updates of the libsane software. Due to
holidays, I cannot tell exactly the version or date when it began to fail.

Kind regards,
Kay Drangmeister

Hi Stephen,

Sounds great ... and I found a bug in the mp150 code. Your scanner
hasn't received the XML end of scan dialog. So you couldn't be able to
start a new scan...

Please test the version +git20170823 from my test ppa. This is the most
recent SANE version from git *with* the bug fix.

Many thanks for your help.

Cheers,
Rolf

Rolf,
I have tried it out with the '$SANE_USB_WORKAROUND=1 scanimage -T'
command on a none-working system and it has not made any difference. The
scanner continues to look busy after the initial scan and a second scan
fails as before.
I had much more success with the git+20170627 version as that worked
okay as you suggested it might.
I am keen to help, test and do what I can to help get the scanner
working correctly, but just to let you know I will be unable to do much
until the 15th September. I am moving home and my ISP won't be
connecting my new place to the internet until then (and thats assuming
no hiccups). I will have mobile internet, so I can receive and send
emails at least, but nothing data heavy.
Kind regards,
Stephen

Hi,
I am using the sane libs (Ubuntu 16.04) with a Canon Pixma MX925
successfully for years now. Since some time (days, maybe weeks), the
scan process does not terminate well.

There were two recent threads about similar issues that may be of
interest

Hi Stephen,

Many thanks for your fast response. I just committed the bug fix into
the master branch. It will be available in my SANE repository tomorrow.

Many thanks again for your help making SANE more stable.

Cheers,
Rolf

Rolf,
Thanks. Tested +git20170823 and it worked perfectly.
I appreciate the work you’ve done in correcting the bug and it certainly
helps me to be able to use the scanner!

Hi Stephen,
Sounds great ... and I found a bug in the mp150 code. Your scanner
hasn't received the XML end of scan dialog. So you couldn't be able to
start a new scan...
Please test the version +git20170823 from my test ppa. This is the most
recent SANE version from git *with* the bug fix.
Many thanks for your help.
Cheers,
Rolf

Rolf,
I have tried it out with the '$SANE_USB_WORKAROUND=1 scanimage -T'
command on a none-working system and it has not made any difference. The
scanner continues to look busy after the initial scan and a second scan
fails as before.
I had much more success with the git+20170627 version as that worked
okay as you suggested it might.
I am keen to help, test and do what I can to help get the scanner
working correctly, but just to let you know I will be unable to do much
until the 15th September. I am moving home and my ISP won't be
connecting my new place to the internet until then (and thats assuming
no hiccups). I will have mobile internet, so I can receive and send
emails at least, but nothing data heavy.
Kind regards,

Hi Jörn-Ingo,

Please test ADF with gscan2pdf.

I know that ADF scanning is faulty for scanners from the mp150 sub backend.

I'm sorry, but I cannot fix this issue because I have no access to such
scanners. I stopped remote fixing issues because I don't have much time
for maintaining SANE anymore.

@List: I can support software developers with ADF scanners fixing this
issue and I can commit patches to git. Affected scanners are all Canon
Maxify and PIXMA types with simple and duplex ADF.

Hope this helps.

Cheers,
Rolf

Hello Rolf,
the Scanner works fluently local in all resolutions now without problems
using latest 1.0.27git01092017 version.
Great!
- ADF (tested with simple-scan), neither locally nor remote via net-backend.
Is there any special setting for this?
- interrupting (stopping) a remote scan from connected clients causes
Scanner infinite scanning and scanline not moving or resetting, only off
and on switching of printer help.
Model is by the way a Canon Maxify MX 2050, my fault.
Great work so far Rolf!
Kind regards,
Jörn-Ingo Weigert
The >600dpi should also be solved with the new version from my ppa.
Cheers,
Rolf

I will wait for it, thanks!
Meanwhile, i would like to remind you of a still existing problem, we
talked about in the past, that scans over 600dpi are possible, but end
result are a overlapping, doubled image, which were also stored as

a non

valid jpeg file..
If you have time to research on it, that would be great. Just drop a
note on that, when.
Kind regards,
Jörn-Ingo Weigert

Could this be a general problem for Pixma aio scanners?
I had to switch back to 1.0.25 after latest update from your

ppa (

sane

1.0.27git20170707¿?) The scan process was interruptive,

stopping,

moving

a bit until reaching ca. 75% of flatbed area the scanner neither

again.
