I have a Canon PIXMA MG5420 printer/scanner that seems to mostly work with sane-pixma backend.  Support for the MG5400 series is still listed as unconfirmed in the documentation.  I would be happy to test my device and report any results.
I am running Ubuntu 16.10 (yakkety) amd64In the Ubuntu package release (sane-utils 1.0.25+git20150528-1ubuntu2), the systemd configuration for saned is broken, but it works fine with the updated build from ppa:rolfbensch/sane-git.  I am using the following:sane 1.0.14-11 amd64
libsane 1.0.26-git20160712sane-utils 1.0.26-git20160712
I primarily use the scanner over a wifi network, and most features seem to workHere is what works:scanning from Simple Scan 3.22.0.1
scanning from XSane 0.999
All resolutions (75, 150, 300, 600, 1200, 2400 dpi)

Here is what doesn't work:
button controlled scanninginitiating scanning from the scanner control panel
For the items that don't work, it is entirely possible that I just don't understand how to configure these features correctly.  With my win7 box with the proprietary Canon IJ network tool installed, I am able to select my computer as a destination for the scanned file, then initiate the scan by hitting either the "Start Color" or "Start B&W" buttons on the pixma front panel.  I am normally unable to see my Ubuntu box on this destination list.  However, if I enterscanimage -d pixma:MG5400_192.168.0.3 --button-controlled=yes > tempimageMy Ubuntu box will temporarily appear in the destination list.  However, I am still unable to initiate the scan.
I don't know anything about the BJNP protocol except what I read in the sane-pixma documentation, but I am happy to learn and help you test.

James

Hi James,

Many thanks for your report.

Your scanner has already been listed as supported in the listing for the
SANE Development (git) Version
(http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA).

You can check if the backend (pixma) implementation supports button
controlled scanning with your scanner:

(1) Connect your scanner via USB, disconnect WiFi

(2) Push any button, which should trigger a scan

(3) Request the pushed button on a console with:
$ SANE_DEBUG_PIXMA=11 scanimage -A

The response should contain data similar like this:

Buttons:
--button-update
Update button state
[pixma] INTR T=1.270 len=32
[pixma] 00000000:00 30 00 00 00 00 00 00 00 00 00 00 00 00 00 00

--original <int> [0] [read-only]
Type of original to scan
--target <int> [3] [read-only]
Target operation type
--scan-resolution <int> [0] [read-only]
Scan resolution

If the response doesn't contain lines starting with [pixma], your
scanner doesn't support button controlled scanning.

If you can see lines starting with [pixma], please report this data for
all available buttons.

Hope this helps.

Cheers,
Rolf

Rolf,


I checked the buttons on my Pixma MG5420.  The data you requested is pasted at the end of this email (connected via usb only, wifi disabled).  I did get output similar to what you posted, but I still can't figure out how to initiate scanning by pushing the buttons on the scanner.  At the T=14.283 log entry, it looks like it maybe captures the button press, but nothing happened.

Also, I re-checked all scanning resolutions and the 1200 and 2400 dpi resolutions do not work.  The scanner will accept these modes and produce a file (png in my test), but it appears to be multiple scans layered on top of each other.  This is not terribly surprising to me since the windows driver only allows me to scan up to 600 dpi.  The 75/150/300/600 dpi modes all work great.

Cheers,james

Hi James,

I'll fix the 1200/2400 dpi issue at the same time when we'll fixed
button controlled scanning.

Your scanner has 2 buttons for button controlled scanning. I need the
response data from each button.

On the scan menu of your scanner you can select the Doc.type. I also
need the response data from each Doc.type's options.

Please select the Doc.type option, push one of the 2 buttons and then
request the scan command with "$ SANE_DEBUG_PIXMA=11 scanimage -A".

I only need the info of the selected option, the pushed button and the
lines starting with "[pixma]". To indentify the buttons I need a scan
with the same options for each button. After this you can test the
Doc.type options with any button you like.

Please consider that for your scanner button controlled scanning isn't
implementey yet. I need all requested info to fix the code.

Many thanks for your help.

Cheers,
Rolf
Rolf,
I checked the buttons on my Pixma MG5420. The data you requested is

can't figure out how to initiate scanning by pushing the buttons on the

Also, I re-checked all scanning resolutions and the 1200 and 2400 dpi
resolutions do not work. The scanner will accept these modes and
produce a file (png in my test), but it appears to be multiple scans
layered on top of each other. This is not terribly surprising to me
since the windows driver only allows me to scan up to 600 dpi. The
75/150/300/600 dpi modes all work great.

Hi James,
Many thanks for your report.
Your scanner has already been listed as supported in the listing for the
SANE Development (git) Version
(http://www.sane-project.org/lists/sane-backends-cvs.html#S-PIXMA).
You can check if the backend (pixma) implementation supports button
(1) Connect your scanner via USB, disconnect WiFi
(2) Push any button, which should trigger a scan
$ SANE_DEBUG_PIXMA=11 scanimage -A
--button-update
Update button state

Button 1

Button 2
--original <int> [0] [read-only]
Type of original to scan
--target <int> [3] [read-only]
Target operation type
--scan-resolution <int> [0] [read-only]
Scan resolution
If the response doesn't contain lines starting with [pixma], your
scanner doesn't support button controlled scanning.
If you can see lines starting with [pixma], please report this data for
all available buttons.
Hope this helps.
Cheers,
Rolf

I have a Canon PIXMA MG5420 printer/scanner that seems to mostly work
with sane-pixma backend. Support for the MG5400 series is still
listed as unconfirmed in the documentation. I would be happy to test
my device and report any results.
I am running Ubuntu 16.10 (yakkety) amd64
In the Ubuntu package release (sane-utils
1.0.25+git20150528-1ubuntu2), the systemd configuration for saned is
broken, but it works fine with the updated build from
sane 1.0.14-11 amd64
libsane 1.0.26-git20160712
sane-utils 1.0.26-git20160712
I primarily use the scanner over a wifi network, and most features
seem to work
scanning from Simple Scan 3.22.0.1
scanning from XSane 0.999
All resolutions (75, 150, 300, 600, 1200, 2400 dpi)
button controlled scanning
initiating scanning from the scanner control panel
For the items that don't work, it is entirely possible that I just
don't understand how to configure these features correctly. With my
win7 box with the proprietary Canon IJ network tool installed, I am
able to select my computer as a destination for the scanned file, then
initiate the scan by hitting either the "Start Color" or "Start B&W"
buttons on the pixma front panel. I am normally unable to see my
Ubuntu box on this destination list. However, if I enter
scanimage -d pixma:MG5400_192.168.0.3 --button-controlled=yes > tempimage
My Ubuntu box will temporarily appear in the destination list.
However, I am still unable to initiate the scan.
I don't know anything about the BJNP protocol except what I read in
the sane-pixma documentation, but I am happy to learn and help you test.
Regards,
James
