Re: [sane-devel] [sane-announce] SANE Backends 1.1.1 released

[Rolf Bensch]

Unfortunately SANE Home (http://www.sane-project.org/snapshots/) 
provides old git snapshots for 1.0.32.


Ubuntu PPA needs git snapshots to generate repository files.

@Povilas, maybe you'd like to fix this on SANE Home.

Hope this helps.

Cheers,
Rolf

Hi all,

I'm happy to announce sane-backends-1.1.1. You can find the latest 
source tarballs here:


https://gitlab.com/sane-project/backends/-/releases.

The page also mentions several "Source code" links in the Assets from
which you can download the git repository corresponding to the release.
Please note that these archives do not include generated files such as
the configure script, Makefile.in files and more.

A nicely formatted version of the release notes is available there too.

One change that is more interesting to package maintainers is that 
with this release the version numbering scheme has been changed and 
thus every new feature release will increment the second version 
number (i.e. 1.2.0, 1.3.0, etc.) and the third number (i.e. 1.1.2, 
1.1.3, etc.) will be left for bugfix releases. Previously feature 
releases used the third version number (i.e. 1.0.30, 1.0.31, etc.) and 
real bugfix releases were not possible. With this possibility present 
more frequent bugfix releases can be expected.


There has been no 1.1.0 release. It was unpublished due to version 
numbering bug in tests that only showed itself after the release was 
made.


In case you encounter any issues with this release, please contact the
sane-devel mailing list or submit an issue:

sane-devel at alioth-lists.debian.net

https://gitlab.com/sane-project/backends/issues

The following is the release notes in the "raw" markdown format. A 
nicely formatted version is available on the GitLab releases page 
mentioned above.

[sane-devel] Release 1.0.33 not available on sane-project.org

[Rolf Bensch]

Hi,

I just noticed on git that SANE 1.0.33 has been released, but it isn't
available neither here:
https://gitlab.com/sane-project/backends/-/releases nor here:
http://www.sane-project.org/snapshots/.

Ralph asked me to do some maintenance on the Ubuntu ppa
(https://launchpad.net/~sane-project/+archive/ubuntu/sane-git). But I
cannot push the release, if it isn't available on sane-project.org.

Hope this helps.

[sane-devel] Maintainer for PIXMA Backend

[Rolf Bensch]

Hi List,

PIXMA backend keeps maintained. I can introduce Povilas as new PIXMA
maintainer.

Povilas is already known as maintainer for the genesys backend. And I
appreciate his XML read/writeback extension to the USB driver. He
replaces my part for everything around scanner implementation.

Louis' part remains everything around BJNP and networking.

I stay subscribed to this mailing list, but already stopped watching the
list. If someone may need me inside some threads in the future, please
add my email address as CC.

The next days I plan to go through my assigned open gitlab issues and
merge request to finalize some small things and to reassign all others
to Povilas. Here the same as for the mailing list, if someone may need
my help in the future please cc me with my gitlab username @ro-ben.

Many thanks for all of your amazing feedback I've received during the
the last few weeks. And many thanks for your ideas, fixes, merge
requests, testing and particularly to your patience for my long response
times.

It was a pleasure working for the awesome SANE project.

Cheers,
Rolf

Hi Kelly,

sane-release for 1.0.31 is available on both repositories:
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-release
and
https://launchpad.net/~sane-project/+archive/ubuntu/sane-release

I planned no auto switching for this ppa. I still added a note to the

The new ppa will provide these builds: amd64, arm64, armhf, i386 and
ppc64el.

After announcing the new ppa, a last update from the old ppa will
reconfigure your systems to the new ppa. So nobody must worry about
switching to the new ppa.

Re: [sane-devel] SANE Backends 1.0.31 released / Goodbye

Hi,

Congratulations to all who contributed his/her ideas, code and at least
time for the new SANE release.

After having some time with reflecting my after-work activities, I
decided to say Goodbye to the SANE project, especially as maintainer for
the pixma backend.

If somebody hears the calling to become a maintainer for the pixma
backend, he/she is welcome to contact me off-list for discussing any
questions about structure and functionality.

Best wishes,
Rolf

I can see your problem. You have a mixed SANE installation: Recent
frontend but ancient backend.

If you've installed SANE from source, however please follow "2.3.1. SANE
library" in INSTALL.linux from your sources folder or from here:
http://www.sane-project.org/docs.html . Then you should be able to
switch to recent backend.

Hope this helps.

Re: [sane-devel] Canon Canoscan LiDE 400 support in Slackware

[Rolf Bensch]

Hi,

My LiDE 400 is working with recent SANE version 1.0.30-914-g8bdd27d14.
You need at lease SANE version 1.0.28.

Please check your installed SANE version with 'scanimage -V'.

This scanner has problems working via USB hosts. You need to connect it
directly to your computer. And I can scan via USB3. But it's not faster
than USB2. It's still connected as USB2 device.

Hopr this helps.

Cheers,
Rolf

Re: [sane-devel] [janitorial] Feature freeze for 1.0.29 and call for translation updates

[Rolf Bensch]

Hi,

I just found new missing German translations, remembered Ulf's great
work and found the branch Olaf created early this year.

To keep the branch close to recent master, I merged it and created a new
merge request for outstanding work:
https://gitlab.com/sane-project/backends/-/merge_requests/487

@Ulf: You're welcome to go ahead checking German translations.

Hope this helps.

Cheers,
Rolf

[sane-devel] PIXMA: Gamma Value & Table

[Rolf Bensch]

Hi PIXMA Users,

I just reworked gamma table calculation. Not all PIXMA scanners need
gamma tables. You can check if your scanner's capabilities with:

$ scanimage --help

So far internal gamma table generation was flawed. Now it produces
feasible results close to Canon's gamma table calculation.

Simply you can use the ideal gamma setting for your scanner, e.g. for
gamma = 2.5:

$ scanimage --gamma 2.5 > test.pnm

Now it becomes a little bit tricky. You can ignore following if you
don't need self generated gamma tables.

PIXMA backend uses two kinds of gamma tables. Old generation 1 scanners
need a table with 4096 * 8bit values. Newer scanners use gamma tables
with 1024 * 16bit values.

You can check your scanner's capabilities with '$ scanimage --help'. You
may see this for 1024 * 16bit tables:

$ scanimage --help
[...]
  Gamma:
    --custom-gamma[=(auto|yes|no)] [no]
    Determines whether a builtin or a custom gamma-table should be used.
    --gamma-table auto|0..65535,... [inactive]
    Gamma-correction table with 1024 entries. In color mode this option
    equally affects the red, green, and blue channels simultaneously
(i.e.,
    it is an intensity gamma table).
    --gamma auto|0.299988..5 [2.2]
    Changes intensity of midtones
[...]

"--gamma-table auto" creates the same table as simply using "--gamma".

Using "--gamma-table" needs "--custom-gamma=true", e.g.

$ scanimage --custom-gamma=yes --gamma-table [0]0-[1023]65535 > test.pnm

generates a linear gamma table from 0 ... 65525 for generation >= 2
scanners.

You can generate your own gamma table with 'gamma4scanimage', e.g.

$ scanimage --custom-gamma=yes --gamma-table `gamma4scanimage 2.2 0 1023
1023 65535` > test.pnm

generates a table close to our internal generated table with gamma=2.2.

Please read '$ man gamma4scanimage' for details.

Hope this helps.

Cheers,
Rolf

If possible, please test if pixma backend is working with your scanner
as USB device.

It would help updating our supported devices list.

Many thanks for your help in advance.

Re: [sane-devel] Sane Test for Canon G3110 Series Scanner (Compatible with G3010 series)

Hi Nubio,

scanimage still sees SANE version 1.0.27.

Please check used SANE version with:
$ scanimage -V

You should see 1.0.29 twice. If not, please go through all steps

Hope this helps.

Re: [sane-devel] Sane Test for Canon G3110 Series Scanner (Compatible with G3010 series)

[Rolf Bensch]

Hi Nubio,

For your scanner you need at least SANE version 1.0.28.

Please check the version installed on your machine.

If Gentoo Linux doesn't support the SANE version above or recent version
1.0.29, you need to install SANE from source, as described in
INSTALL.linux (http://www.sane-project.org/docs.html).

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon imageClass MF4770n

[Rolf Bensch]

Hi,

I don't look through Canon's marketing policy how they name their
devices. It's not such easy as it looks like: EU = 5, US = 7.

E.g.: For Canon imageClass MF4700 Series I found these models:
MF4720, MF4730, MF4750, MF4770 and MF4780 (1x Asia, 3x Europe, 1x US).

For other models Canon is also playing with the suffixes:
e.g. amongst others i-SENSYS MF210 Series provides these scanners:
MF211, MF213w, MF215, MF217w. Some Asian, Europe and US.

Some time ago I asked me the question, how to identify all available
scanner family members all over the world. I stopped this after
searching a small amount of scanners on Canon's international websites.
It's a real torture.

I decided to follow Canon's policy for their scanner drivers, to use the
family names, e.g. Canon imageClass MF4700 Series.

Adding some explanation in pixma scanners section header
(http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA) could
help, what 'Series' stands for. Or using a 'x' could also help, e.g.
'Canon imageClass MF47x0', without 'Series' and suffixes but with an
explanation in the section header.

What do you think about this?

Cheers,
Rolf

[sane-devel] escl backend and ippusbxd

[Rolf Bensch]

Hello,

I've seen that some people need to purge |ippusbxd| before they can use
their scanner with escl backend (e.g.
https://gitlab.com/sane-project/backends/-/issues/256#note_307051019).

Is this a fix rule? Then I'd like to add a break dependency to
|ippusbxd| in my Ubuntu ppa.

Cheers,
Rolf

Re: [sane-devel] Where do I download the software for a Canon Pixma TR4520?

Hi Chris,

Your scanner should work via USB or over network with the escl backend.
Please check the used SANE version:
$ scanimage -V
scanimage (sane-backends) 1.0.29-290-g787b89da; backend version 1.0.29

Please have a look here:

Re: [sane-devel] Canon i-sensys MF720C Series is not supported by sane-pixma backend

[Rolf Bensch]

Hi Petr,

Today I added your scanner to SANE sources.

You can rebuild SANE from sources now, or if you have Ubuntu or an
Ubuntu clone, you can update SANE from my ppa
(https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git) tomorrow.

If you might have any problems, please create an issue here:
https://gitlab.com/sane-project/backends/-/issues . It's easier to use
the issue tracker than using the mailing list, if we need to exchange
any logfiles.

Please also report when your scanner is working.

Hope this helps.

Cheers,
Rolf

Hi Ismet,

For Ubuntu you can use my ppa, if you don't want to edit some source
files and need to biuld SANE by yourself:

Hope this helps.

Yes, this is correct. Pixma backend supports only symmetric scan
resolutions, so the highest available is 600dpi for your scanner.

Please have a look at INSTALL.linux, "2.3.1. SANE library". Maybe you're
using SANE installed from your distro's repository. After this gscan2pdf
should also see the usb scanner.

You're welcome.

Re: [sane-devel] Canon TR4529 (PIXMA TR4500 Series)

[Rolf Bensch]

Hi,

Installation is described in INSTALL.linux, which comes with the source
files (or read here: http://www.sane-project.org/docs.html). Please give
me a short note if anything is missing there.

You can reduce build time by selecting the desired backends, e.g. for
escl and pixma:
$ ./configure --enable-avahi BACKENDS="escl pixma"

Due to a bug you need to manually enable avahi for escl.

I prefer using xsane as frontend. If you still want to use scanimage,
here are some examples for simple usage:
$ scanimage --help
$ scanimage > image.pnm
$ scanimage --resolution 300 --format=jpeg > image.jpg

Redirecting debug info to a file:
$ SANE_DEBUG_PIXMA=11 scanimage 2> scan.log > image.pnm
$ SANE_DEBUG_PIXMA=11 xsane 2> scan.log
Please have a look at the man pages if you want to see debug infos from
other backends than pixma.

Please try my previously provided patch for the pixma backend and test
scanning 1200 dpi images. To do this you should connect your scanner on USB.

escl is a concurrent backend providing AirScan/eSCL network protocol.
For older Canon scanners you can still use pixma backend with BJNP and
MFNP protocol support. For new scanners Canon switched to AirScan/eSCL
protocol and for these scanners you need escl backend.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon TR4529 (PIXMA TR4500 Series)

[Rolf Bensch]

Hi Jean-Marc,

With my patch please also test scanning from ADF and send me a logfile.

For ADF scans I prefer gscan2pdf:
$ SANE_DEBUG_PIXMA=11 gscan2pdf 2> tr4500-adf.log

These tests are for the pixma backend using USB connection.

Many thanks for your help.

Cheers,
Rolf

Re: [sane-devel] Canon Canoscan LiDE 400 support in Slackware

[Rolf Bensch]

Hi,

The LiDE 400 is fully supported by the pixma backend (see:
http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA). You
need to install recent SANE version 1.0.28 from git snapshots
(http://www.sane-project.org/snapshots/).

Hope this helps.

Rolf

Re: [sane-devel] [janitorial] Feature freeze for 1.0.29 and call for translation updates

[Rolf Bensch]

Hi Olaf,

What branch do we provide in git snapshots, master or release/1.0.29?

Hope this won't confuse too much.

Cheers,
Rolf

Hi Kelly,

Please have a look here:

If you need a more recent version of SANE, you can use my other ppa:
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git

Hope this helps.

Re: [sane-devel] [janitorial] New backend: escl

[Rolf Bensch]

Hi,

Congratulations for finishing this job.

Is there a (nearby complete) list of pixma scanners available, which are
supported by escl?

I would like to update pixma's doc files and include building escl when
a user selects only pixma at ./configure.

Many thanks.

Cheers,
Rolf

Re: [sane-devel] Canon i-sensys MF744Cdw

[Rolf Bensch]

Hi Ford,

Have you tried to scan via USB or WiFI/Ethernet? Try to scan via USB first.

If you still may have problems, please create an issue here:
https://gitlab.com/sane-project/backends/issues . It's easier to
exchange log files and patches from there. Please upload a logfile
created from the console:

$ SANE_DEBUG_PIXMA=11 scanimage 2> mf744.log > test.pnm

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon TR4529 (PIXMA TR4500 Series)

[Rolf Bensch]

Hi Jean-Marc,

The Pixma backend just doesn't support 600x1200dpi. Sorry, this was my
fault.

Please patch the source backend/pixma_mp150.c with the attached file and
try ADF scans again. I suppose that Canon changed ADF data format for
all new scanners.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] New backends eSCL

[Rolf Bensch]

Hi Thierry,

Maybe it could be an good idea to implement eSCL protocol early to SANE,
e.g. with a merge request. There are several Pixma users who want to use
WiFi or Ethernet.

How stable is the beta version? If you're not sure if the implementation
is too early, you can use an evironment variable to enable eSCL.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon Pixma MX495

[Rolf Bensch]

Hi,

scanimage needs a redirection to the image output and a separate
redirection to the debug outputs, e.g.

SANE_DEBUG_PIXMA=11 scanimage <...> 2> mx495_adf.log > image.pnm

For gui frontends you can use the combined redirection, e.g.

SANE_DEBUG_PIXMA=11 xsane &> mx495_adf.log
SANE_DEBUG_PIXMA=11 gscan2pdf &> mx495_adf.log

I suppose that you need to patch pixma_mp150.c with attached patch file
for enabling adf scans.

Please report your results.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon Pixma TS6260 / Ubuntu 18.04

[Rolf Bensch]

Hi John,

As you can see here
(http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA), we
don't support WiFi yet. Maybe Canon's new WiFi protocol will be
implemented later.

If you need WiFi, you should stay at the scangearmp2 project. You can
use SANE with USB.

Hope this helps.

Cheers,
Rolf

Do you have one or two sheets in the document feeder?

The imageclass sub-backend has a timeout function for inserting sheets
into the document feeder after the scan has been started. I think it
should be similar for the mp150 sub-backend. The timeout has a parameter
(adf-wait) which can be set from any frontend. Sorry, I cannot test
this. I haven't any scanner with ADF.

(1) push any button
(2) from a console call:
$ SANE_DEBUG_PIXMA=11 scanimage -A

You should find this inside the response:
...

I pushed a button which has been detected as "target no. 5". Each button
has it's own target number.

--button-1 and --button-2 are historical buttons from old mp150 devices.

Some multi functional scanners use menu driven buttons. Then you can set
the target and the scan resolution from scanner's menu and this info
will be shown from the particular parameters.

You can see different button implementations in function handle_interrupt().

Re: [sane-devel] Canon Pixma MX495

[Rolf Bensch]

Hi,

I just had a look at this ppa. The builds are ancient (from 2013). Canon
released MX495 in 2015 (as documented in Sane sources).

If you need to install recent Sane to Ubuntu or an Ubuntu clone, you can
use my ppa:  https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git

Hope this helps.

Re: [sane-devel] Canon Pixma MX495

[Rolf Bensch]

Hi Franz,

For adf scans I would prefer to use gscan2pdf.

Before scanning via WiFi, for reference please scan via USB with
disabled WiFi first.

If scanning from adf still fails, please create an issue here:
https://gitlab.com/sane-project/backends/issues and upload a logfile
created from a terminal (usually uploading logfiles to the mailing list
fails due to file size restrictions):

$ SANE_DEBUG_PIXMA=11 gscan2pdf &> mx495_adf.log

Many thanks for your help.

Re: [sane-devel] Canon Pixma TR8550 support

[Rolf Bensch]

Hi Sedat,

For Ubuntu you can use my ppa to get the recent builds:
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git .

For Debian you should install Sane from source, if you want to get a
recent version. For details please read INSTALL.linux
(http://www.sane-project.org/docs.html).

You can find recent information from Sane's website:
http://www.sane-project.org/ .

Please report if both, (1) 1200 dpi scans and (2) scanning from document
feeder are working.

Many thanks for your help.

Hi JMS,

feeder are working. You scanner still is marked as "untested"
(http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA).

I wouldn't use Ubuntu's deb packages for Debian. You need libjpeg if you

Sorry, but I don't know what makes you believe, that using merge
requests completely avoids compile errors. In my long life as git user
I've seen a lot of messed code from git merges, especially from merging
"ancient" branches without rebasing the branches to recent master (and
fixing possible problems inside the affected commits), and/or if a group
of power developers are working on the same files. Breaking code with a
branch can still happen, even if somebody else must approve the changes
and/or must process the commit.

In the near past we've seen some build problems which have not been
detected by Sane's continuous integration system. On the other hand
every push is running through CI and the committer will get an email if
any problem has been detected. Maybe we should change existing jobs
and/or add more jobs to CI if we identify such problems.

We must not forget that master branch is under development and if
somebody pulls recent code from git or downloads recent code from Sane's
webside, the code might be faulty and that we (the developers /
maintainers) are happy for any feedback.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Sending confirmation about the pixma backend

Hi Rogério,

I opened a merge request for your issue here:
https://gitlab.com/sane-project/backends/merge_requests/213

Please build SANE from source as described in INSTALL.linux
(http://www.sane-project.org/docs.html).

If this is working, please pull recent code from git ($ git pull),
checkout our test code ($ git checkout pixma/e4200-adf) and build SANE
again. Then ADF should work. Please report your results in the merge
request.

Many thanks for your help.

Re: [sane-devel] Proposal to disallow direct pushes to the master branch

[Rolf Bensch]

Hi Povilas,

I think using branches depends on the complexity of the changes|fixes.

Document file updates and simple fixes which don't change "my" backend's
functional structure can be committed directly into master.

If new code touches my backend's functional structure, other backends or
sane common functions, it should be recommended to use branches.

If I'm working for myself and if only my backend is affected, I can use
local branches and I only need to push master after local merge. I don't
see any benefit for using a merge request in gitlab for this. Then the
commit messages should explain my changes. And if my branch stays local,
I can use git's versatile functions like rebase.

If other people need to be involved, e.g. for testing, a merge request
in gitlab is appropriated for communication. This is more transparent
than discussing things via the mailing list or even off-list.

If another backend is affected or sane common code, a merge request in
gitlab should be mandatory. And this merge request should be approved by
other(s). This can help to avoid breaking "foreign" code.

Hope this helps.

Cheers,
Rolf

The scan resolutions are restricted by hardware. If you need another
scan resolution you must use an external image converter program. But
you won't win anything if you increase the scan resolution. No program
can create contents which isn't available on the 600dpi scan.

> What document formats are available for scanner output (on Linux of course)?

At the frontend you can set the desired scan area. E.g. in xsane you can
set the scan borders in a preview window.

Hope this helps.

To fix this I need an USB snoop file from Canon's ScanGear Software. You

--souce option usually resets previous settings.

Please try this:

$ scanadf -d pixma:04A91855_103CD1 --source "Automatic Document Feeder"
--mode Lineart --output-file foo%02d.pbm

For testing ADF I prefer to use gscan2pdf and for "normal" scans xsane.
You can see some logs with:

$ SANE_DEBUG_PIXMA=11 gscan2pdf

or

$ SANE_DEBUG_PIXMA=11 xsane

add this if you want to save the log into a file:

&> pixma.log

You can decrease the log level to reduce log depth (see 'man sane-pixma'
for details).

Please have a look at this table:

Hope this helps.

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.

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

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

Re: [sane-devel] Canon TS8000 series PIXMA

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.

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

[Rolf Bensch]

Hi Vilnius,

Many thanks for your feedback.

However, ADF support was missing in the device definition. I just fixed
this and you can test ADF support with the next version from my PPA
tomorrow.

Please also test Ethernet / WiFi support.

Hope this helps.

Cheers,
Rolf

Hi JMS,

Sorry, I was confused with the numbers. SANE 1.0.28 is the recent
version you need.

Hope this helps.

Re: [sane-devel] Canon TR4529 (PIXMA TR4500 Series)

[Rolf Bensch]

Hi JMS,

What SANE version is installen on your system? You need version 1.0.29.

If you're using Ubuntu or an Ubuntu clone, you can use my ppa to update
SANE: https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git .

If you have another Linux OS, please install SANE as described in
INSTALL.linux (http://www.sane-project.org/docs.html).

Please try to scan all dpi resolutions and after this the document feeder.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon ImageClass MF644Cdw

[Rolf Bensch]

Hi Kip,

As Olaf mentioned before, your scanner is implemented in stable SANE version 
1.0.28 (http://www.sane-project.org/sane-backends.html#S-PIXMA), but not tested 
yet.

If you're using Ubuntu or an Ubuntu clone, you can use my ppa to update SANE: 
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git .

If you have another Linux OS, please install SANE as described in INSTALL.linux 
(http://www.sane-project.org/docs.html).

If your scanner can be found by SANE, please test scanning all dpi resolutions 
and the document feeder with single/multiple pages, single side and duplex. 
Maybe you want to test WiFi support.

Hope this helps.

Cheers,
Rolf

Hi Patrick,

I just fixed ADF scanning for other Maxify scanners and committed the
same fix to your scanner. The fix will be available from my PPA
tomorrow. Please report your results scanning from ADF.

Hope this helps.

Re: [sane-devel] Canon MB5050 and ADF

[Rolf Bensch]

Hi Louis,

I just committed your suggested fixes for your MB5050 and other MB scanners.

Do you already have some test results from your new MB5450? What's about
scanning with 1200 dpi? I'll update MB5100 settings when your new
scanner is working, due to near USB PID.

Hope this helps.

Cheers,
Rolf

[sane-devel] autoconf needs git clone

[Rolf Bensch]

Hi Olaf,

Debian and Ubuntu use autoconf for building their repositories. Since
git commit bf00b9f49 they need a full git clone for running through
'configure.ac'.

For my PPA I created a patch to revert this commit.

On the other hand, after a git gull I always need to call './autogen.sh
&& ./configure' to see the updated git version in my manually builds, e.g.
$ scanimage -V
scanimage (sane-backends) 1.0.28-3-g90684c53; backend version 1.0.28

This is annoying any I think you had another idea behind your commit.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon MG3050

[Rolf Bensch]

Hi Kamp,

No wonder, your SANE installation is outdated and doesn't support
MG3050. SANE version must be >= 1.0.27. Please update SANE e.g. from my
PPA: https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git .

Due to your scanner is in 'untested' status, please try to scan via USB
first. If this is working, then you can switch to WiFi.

Debug hints and BJNP setup are described in the man page '$ man sane-pixma'

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Code freeze and release preparations for 1.0.28 (was Re: [ITR] Intent To Release: sane-backends-1.0.28)

[Rolf Bensch]

Hi all again,

Today I merged my German translations into master branch. Everybody
still is invited to review my translation until July 31. Also after the
new release will be out, of course.

Please consider that new localization files may break existing scanimage
scripts.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon TS8000 series PIXMA

[Rolf Bensch]

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

Hi Olaf,

It would be nice to see some tags in git, as reminder for the recent
stage in our release process.

This is just an idea for the discussion how to organize such things in
future.

Re: [sane-devel] Canon MF264 bad scan results

[Rolf Bensch]

Hi Sergey,

Sorry for the late response.

Do you get corrupted output from all scan resolutions?

If possible, please provide an USB log file e.g. from Windows with
wireshark (https://wiki.wireshark.org/CaptureSetup/USB).

Hope this helps.

Cheers,
Rolf

I'd like to see something like a simplified git-flow:

master - for releases
develop - all ongoing development (source for git snapshot)
release branches - created on develop @ feature freeze
  - may contain tags like "1.28.0-code_freeze"
  - merge to develop if necessary
  - merge to master if ready

All merges should be done with the option --no-ff .

Cheers,
Rolf

Hi Mark,

A "normal" package update should also update SANE from the PPA and
install new dependencies if you haven't removed the PPA from apt, e.g. with:

$ sudo apt-get update && sudo apt-get upgrade

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon TS8000 series PIXMA

[Rolf Bensch]

Hi,

I would follow the install instructions from INSTALL.linux which comes
with the sources or from here: http://www.sane-project.org/docs.html

@Tim: Is high resolution scan (1200 dpi) and are all other options
working? I would like to update scanners status page here:
http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA

Many thanks for your help.

Cheers,
Rolf

Hi,

I just fixed the ppa build dependencies for trusty and xenial. Newer
Ubuntu versions are not affected. The ppa is building now.

Re: [sane-devel] Xsane --> Canon Pixma scanner problems

[Rolf Bensch]

Hi,

Yesterday I merged the merge request bachends/!43. You can update SANE
from my Ubuntu ppa
(https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git) later today.

Please report if the scanner is working with SANE, especially scans >
600dpi.

Before you start with WiFi connection, please test USB first.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Xsane --> Canon Pixma scanner problems

[Rolf Bensch]

Hi Bill,

Your scanner isn't supported by SANE. I suppose you're using Canon's
ScanGear driver. Please ask Canon for technical support.

Maybe somebody else can help with your xsane issues.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon imageCLASS MF416dw & Ubuntu 18.04

Hi John,

Please start test scanning via USB.

If I remember correctly, you need to set your scanner into remote
scanning mode. Please read your scanner's manual for details.

Hope this helps.

Re: [sane-devel] Canon imageCLASS MF416dw & Ubuntu 18.04

[Rolf Bensch]

Hi,

You need to install SANE's development version, e.g. from my PPA:
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git .

The MF410 Series is supported since PIXMA backend version 0.17.51 (SANE
version 1.0.27), but still has status 'untested'.

Hope this helps.

Re: [sane-devel] SANE Support for Canon TS9520 printer

[Rolf Bensch]

Hi Paul,

I just added your scanner to SANE. It's available in git now. For other
download channels you must wait until tomorrow.

Please check if everything is working. For these kind of scanners SANE
has problems with Ethernet and WiFi, so only USB might work.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Pixma sane backends

[Rolf Bensch]

Hi Irene,

Please compare the versions of libsane on both OS.

Is your scanner working via USB on CentOS 7? If so, please read 'man
sane-pixma' howto setup network.

If nothing helps and CentOS 7 has a too old libsane, you must compile
your own binaries from source. Please read INSTALL.linux
(http://www.sane-project.org/docs.html) for details.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] Canon imageClass MF733

[Rolf Bensch]

Hi Carl,

Your scanner was working before you installed Canon's printer driver and
ist working again after deinstalling the printer driver, right?

If I remember correctly there should be an old thread handling this
issue. Please ask the mailing list if you cannot find it. Sorry, I
cannot help here.

Maybe Ethernet could also fix this issue. Please read 'man sane-pixma'
for details. If this won't help, please ask the mailing list helping
with Ethernet.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] sane-pixma TS6150

[Rolf Bensch]

Hi Giles,

Yes, the PPA is compiled with libusb. I just tested Ubuntu 18.04 with my
USB scanner.

I've seen in the log file that you might have connected your scanner
with WiFi. Please disconnect WiFi and test the scanner via USB only.

Please test with this command:
$ SANE_DEBUG_PIXMA=21 scanimage 2>pixma.log >pixma.pnm

and send me the logfile compressed as zip file.

If this won't help, I'll need an USB scan log from a Windows machine
using wireshark (read this for enabling USB support:
https://wiki.wireshark.org/CaptureSetup/USB) or USBlyzer
(http://www.usblyzer.com/download.htm). You can also run Windows in a
VM, e.g. VirtualBox. Please send this log file also compressed with zip.

Hope this helps.

Cheers,
Rolf

[sane-devel] canon d570

[Rolf Bensch]

Hi Steve,

I'm sorry for the late response.

I just added the D570 scanner to SANE. Please test the recent version
from git and report your results. If everything is fine, I'll update the
doc files and the scanner's status here:
http://sane-project.org/lists/sane-backends-cvs.html#S-PIXMA  (maybe it
will take a little while until the website will be updated).

Cheers,
Rolf

Re: [sane-devel] sane-pixma TS6150

[Rolf Bensch]

Hi Giles,

As I mentioned before, very probably your scanner cannot be used via
Ethernet and WiFi. Please retry scanning via USB connection. Then you
should remove the Ethernet cable and/or disable WiFi.

Hope this helps.

Cheers,
Rolf

Re: [sane-devel] sane-pixma TS6150

[Rolf Bensch]

Hi Giles,

I'm sorry to tell you that your scanner isn't supported by SANE. You
confuse your TS6150 with the TS6050 (PIXMA TS6000 Series).

There's another problem with the tested TS scanners: WiFi isn't working.

I can quickly implement your scanner to SANE, but you very probably need
to use the scanner USB connected to your PC. Please send me your
scanner's USB IDs, which can be indentified on a console with:
$ lsusb
Bus 002 Device 007: ID 04a9:1908 Canon, Inc.
...

Hope this helps.

Cheers,
Rolf

Hi,

Attached you find a possible patch for the 1200dpi issue. Please report
if it's working.

Many thanks for your help.

Re: [sane-devel] Canon imageClass MF733

[Rolf Bensch]

Hi Carl,

I just added your scanner to SANE. It will available from the daily git
snapshots tomorrow. Or from my Ubuntu PPA
(https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git), also tomorrow.

First you should test the USB connection before you maybe want to switch
to ethernet/wifi.

Hope this helps.

Cheers,
Rolf
