Brother scanner not detected in ubuntu 16.04

[david_brown6]

Me 2, unfortunately. I've previously had difficulties installing Brother DCP-J315W in last two versions of Ubuntu but got there eventually after lots of pain & hours.

This time, 16.04 upgrade failed so I was forced into another re-install. I followed the usual process, installed drives etc, printer works, sane-find-scanner sees the beast, but sudo xsane says "no devices available". Suffice to say simple-scan fails.

The only difference in the install process I noticed was 40-libsane.rules may now be named 60-libsane.rules but I've edited the new file as usual and still no joy. Interestingly, I was sure I edited 40-libsane.rules yesterday, early in the process but when I went looking for this file today, could only find 60-libsane.rules and it needed editing again???? Huh, I could only think that some updates came through and reset that file. Something weird and wonderful happened there.

I'm in contact with Brother in Oz and they say nothing has changed - just follow the old installation process. I'm calling BS but will have to wait till Monday before I can phone them.

Far from happy and hoping to see some good advice from others on this thread.

OOPS - hadn't seen the solution on page of thread....... I did the cp -r /usr/lib64/sane /usr/lib/sane thingee and it worked for me too. Yeh, cheers, champagne.




Cheers

Found this to be incredibly helpful:

export SANE_DEBUG_DLL=128
scanimage -L

[dll] load: trying to load `/usr/lib/x86_64-linux-gnu/sane/libsane-brother3.so.1'

Per the previous suggestion, you must copy the files or create a link.

I think I have a solution! For those who can read French, here is the link.
For the others, I will tell you what I did (Arsène Leiris is my pseudonym in the French forum).

This works for the Brother DCP-195C, but I guess it will work for other models.

First I installed the brother pilots thanks to the automated script given by Brother here.
Then I used another script given by Brother to resolve the permissions issue.
I edited /lib/udev/rules.d/40-libsane.rules by adding

# Brother scanners
ATTRS{idVendor}=="04f9", ENV{libsane_matched}="yes"

before the line "# The following rule will disable".
Finally I followed the instructions here. But instead of copying some of the files to /usr/lib/sane , I copied them to /usr/lib/x86_64-linux-gnu/sane (I use Ubuntu 16.04 64 bits). If you use the 32 bits version, copy the files to /usr/lib/i386-linux-gnu/sane .
Here is what I did specifically:

sudo cp /usr/lib64/libbrscandec3.so.1.0.0 /usr/lib
sudo cp /usr/lib64/sane/libsane-brother3.so.1.0.7 /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/sane/libsane-brother3.so.1 /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/sane/libsane-brother3.so /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/libbrscandec3.so /usr/lib
sudo cp /usr/lib64/libbrscandec3.so.1 /usr/lib

I tested a whole bunch of "solutions" one after the other so maybe one should start by copying the files in the directories that are indicated here. I am not sure if all these steps are necessary, but it eventually worked for me ^^' Thanks a lot to ares who gave me a solution!
To put things into context, the scanner of my multifunction Brother printer DCP-195C was not detected by xsane (as explained extensively in the French forum).

Pass the solution around!

[krisbeazley]

This did the trick. Thank you for your answer.

I had to:
sudo mkdir /usr/lib/sane
sudo cp * /usr/lib64/sane/* /usr/lib/sane/

Scanner now works.

[klaus15]

Thank you for the help.
I had to do both:

sudo mkdir /usr/lib/sane
sudo cp * /usr/lib64/sane/* /usr/lib/sane/

and

sudo cp /usr/lib64/libbrscandec3.so.1.0.0 /usr/lib
sudo cp /usr/lib64/sane/libsane-brother3.so.1.0.7 /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/sane/libsane-brother3.so.1 /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/sane/libsane-brother3.so /usr/lib/x86_64-linux-gnu/sane
sudo cp /usr/lib64/libbrscandec3.so /usr/lib
sudo cp /usr/lib64/libbrscandec3.so.1 /usr/lib

After that Simple Scan and Xsane workt worked perfectly fine with my MFC-9840CDW (networked) on my amd64 installation.
On two other systems with i386 installation I just needed to follow the instructions on the Brother site to make it work.

My FIX

My Brother DCP-J140W wifi printer+scanner stopped working after a 16.04 install. The Brother Installer complained about some unknown directories, bad file descriptors, etc. I eventually reinstalled CUPS then re-ran installer. Now printer + scanner working. As follows:

apt-get purge
apt-get install cups
sudo bash linux-brprinter-installer-2.0.0-1 DCP-J140W

Hope this helps

Great

I have it working. Looks like with 64-bit Ubuntu you have to copy /usr/lib64/sane to /usr/lib/sane for it to work.
see http://ubuntuforums.org/showthread.php?t=2043258

Thank you so much for that. Had tried all sorts but that works.

[roger_1960]

This

sudo mkdir /usr/lib/sane
sudo cp * /usr/lib64/sane/* /usr/lib/sane/

Solved the scanner not working issue under 16.04 for me with my DCP-J315W (having already followed Brother's instructions which worked for 14.04)

Many thanks to those who enlightened us!

[Gary_C_Bellaire]

This worked for me with a brsane type 3 printer.

In viewing this thread and noticing that some people had problems, while others did not, I found that the problem may actually be tied to specific Brother brsane drivers, not to all of them.

Brother's Linux page shows 4 brsane drivers, each of which supports certain specific Brother scanner models.

I have 2 Brother scanners - an MFC-7440N, which uses brsane3, and an MFC-J430W, which uses brsane4. The MFC-J430W installed cleanly under Ubuntu 16.04 by following the Brother Linux documentation. No special copying was needed. The MFC-7440N, however, uses brsane3, and that's the scanner that caused me fits until I tried the solution quoted below.

FYI.

I barely know what I am talking abou t --but I had same problem several years ago with another ubuntu distro--found this then and saved it. I just installed brother drivers for my MFC7420. Printer worked, scanner not recognized. The fix I found previous was added and it worked both in simple scan and in gimp /xsane. It is for a usb printer. so if you have a USB, maybe try it. If you are not usb-- I wouldn't attempt it. Either way, make a back up. modify you udev 50 rules . lib/udev/ 50 udev default rules---- it may over ride this next time you boot--- I don't know as I have kept computer on. add the following after this SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664"

then add this : SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ENV{ID_USB_INTERFACES}=="", IMPORT{program}="usb_id --export %p"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", ENV{ID_USB_INTERFACES}==":0701*:", GROUP="lp", MODE="0666"

I then went back to the subsytem and change 0664 to 0666.

I really don't know what I am doing ---but this has worked for me twice --- once with 9.10 and now for 16.04

hope it helps
