How to access Brother network scanners
In the file /lib/udev/rules.d/40-libsane.rules
were the following 2 lines (starting at line #42):
# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"
I commented out the 2nd line after reading this, Zvlwab's 2nd comment, who stated that the line above is not needed and it conflicts with the ia32-libs.
Then, I enter the following command, being sure to include apostrophes around the device name:
scanimage --test -d 'brother3:net1;dev0'
The Invalid argument
no longer appears and network scanning on the MFC-7840W now works!

I have two network/USB all-in-ones that are in separate networks, Brother MFC-7840W and Brother MFC-9840CDW. The operating system is Ubuntu 14.04 LTS on a
x86_64
system. USB works for printing and scanning for both. Network access used to work for printing and scanning for both units.Now, network printing works on the MFC-9840CDW, but does not work on the MFC-7840W, and network scanning does not work on either. There have been some recent OS auto-updates and I've installed/un-installed several software programs. But I haven't changed the driver for the scanners and printers, so I'm unaware of any apparent reason it has suddenly stopped working.
How can I regain network access for scanning on my Brother all-in-ones?
Here are the actions I've taken:
In the terminal, I enter the command:
scanimage --list-devices
which outputs:
[pixma] udp_command: No data received (select): timed out [pixma] udp_command: No data received (select): timed out [pixma] udp_command: No data received (select): timed out [pixma] Cannot read scanner make & model: *�� device 'brother3:net1;dev1' is a Brother MFC-9840CDW Scanner-MFC-9840CDW device 'brother3:net1;dev0' is a Brother MFC-7840W Scanner-MFC-7840W
It seems that the devices are connected.
To test the device, I enter the command:
scanimage --test 'brother3:net1;dev0'
which outputs:
[pixma] udp_command: No data received (select): timed out [pixma] udp_command: No data received (select): timed out [pixma] udp_command: No data received (select): timed out [pixma] Cannot read scanner make & model: a�i$ <b>scanimage: open of device brother3:net1;dev1 failed: Invalid argument
...Why isn't the MFC-7840W device (brother3:net1;dev0) showing?...
Then, I open the file: /usr/local/Brother/sane/brsanenetconfig3.cfg, which outputs the following two lines:
DEVICE=Scanner-MFC-7840W , "MFC-7840W" , 0x4f9:0x1e5 , NODENAME=BRN904CE598109B DEVICE=Scanner-MFC-9840CDW , "MFC-9840CDW" , 0x4f9:0x1cc , NODENAME=BRW29571E
I think the 2nd line may be causing my problem, so I comment it out:
DEVICE=Scanner-MFC-7840W , "MFC-7840W" , 0x4f9:0x1e5 , NODENAME=BRN904CE598109B #DEVICE=Scanner-MFC-9840CDW , "MFC-9840CDW" , 0x4f9:0x1cc , NODENAME=BRW29571E
Then, I return to the terminal and re-enter the command:
scanimage --test 'brother3:net1;dev0'
which outputs:
[pixma] udp_command: No data received (select): timed out [pixma] udp_command: No data received (select): timed out [pixma] udp_command: No data received (select): timed out [pixma] Cannot read scanner make & model: q*& scanimage: open of device brother3:net1;dev0 failed: Invalid argument
Why is there an "Invalid argument"?
Then, I enter the command:
dpkg -l | grep Brother
which outputs:

What could/should I do to gain access to my Brother MFC-7840W network scanner?
UPDATE 1: Based on comments, I copied the files
libsane-brother*
andlibbrscandec*
to the folders/usr/lib/sane
and/usr/lib
.To test the device, I enter the command:
scanimage --test 'brother3:net1;dev0'
which outputs:
scanimage: open of device brother3:net1;dev0 failed: Invalid argument
It seems I'm a step closer to the solution, but the MFC-7840W device (brother3:net1;dev0) is still not working.
UPDATE 2: I enter the command:
dpkg -L brscan3
, which outputs the following, copied to include only files in/usr/lib64
:/usr/lib64 /usr/lib64/libbrscandec3.so.1.0.0 /usr/lib64/sane /usr/lib64/sane/libsane-brother3.so.1.0.7 /usr/lib64/libbrscandec3.so /usr/lib64/libbrscandec3.so.1 /usr/lib64/sane/libsane-brother3.so.1 /usr/lib64/sane/libsane-brother3.so

fixer1234 over 9 yearsYou say you used to be able to access both over the network. Has anything changed on the system or did it suddenly stop working for no apparent reason? Printing to both works properly? Working on USB, is it that it previously worked on USB or since the network problem, you tested USB and it works?

Arya over 9 yearsThings have changed on the system, such as recent OS auto-updates, personal files, and I've installed/un-installed several software programs. But I haven't changed the drivers for the scanners and printers, so I'm unaware of any apparent reason it has suddenly stopped working. Network printing works on the MFC-9840CDW, but does not work on the MFC-7840W. USB scanning and printing works on both devices.

Olaf Dietsche almost 9 yearsI also had the
scanimage: open of device brother:net1;dev0 failed: Invalid argument
error message. I finally solved it with help from bugs.launchpad.net/ubuntu/+source/simple-scan/+bug/848575/…. See also my answer at askubuntu.com/a/663386/108339 -
Arya almost 9 years@OlafDietsche I copied
libsane-brother*
andlibbrscandec*
to/usr/lib/sane
and/usr/lib
. The same Invalid argument error message appears. -
Olaf Dietsche almost 9 years@Arya You must also copy
libbrcolm*
to/usr/lib
. -
Olaf Dietsche almost 9 yearsYou also seem to have a mix of
i386
andamd64
packages. What is the architecture of your system? If you have ai386
system, then you must install thei386
brscan* package of course. -
Arya almost 9 years@OlafDietsche I did not locate
libbrcolm*
any where on my system after doing a search. The architecture of my system isx86_64
. -
Olaf Dietsche almost 9 yearsThen
brscan3
seems to be different from mybrscan
. Maybe there are still other libraries, which must be copied. Check withdpkg -L brscan3
, which libraries are installed in/usr/lib64
or maybe even somewhere else. -
Arya almost 9 years@OlafDietsche I entered
dpkg -L brscan3
, the results of which are copied into the main window above due to character restrictions in commenting. -
Olaf Dietsche almost 9 yearsIf these are all libraries in the package, I have no idea what the problem might be in your case, sorry.
