No Scanner Found...Brother MFC-440CN
 

Need help with drivers I assume. Dell Inspiron 546, 64bit, running Linux Mint 18. Installed drivers (see attachment) for my USB MFC-440CN. Printer works fine but no scanner found (see Find Scanner attachment). After reading many, many posts, I'm more confused than when I started. There are many suggestions on what to try but up to now...NG. Any help will be appreciated.

You have two scanner drivers installed. The correct driver for your device is the brscan2 0.2.5-1.
I suggest that you check the contents of your /etc/sane.d/dll.conf file. There should be an entry 'brother2' at the end of that file.
Alternatively, remove both drivers and then reinstall the appropriate driver.
I find that the 'scanimage -L' command is required to show my Brother device. The 'sane-find-scanner' command fails.

I removed brscan2 & 3 and reinstalled brscan2 as shown on the "Brothers Drivers" file and ran a scanimage -L command and still no scanner listed. I'm not sure what you mean by "check the contents of your /etc/sane.d/dll.conf file" Attached is a file of the dll file and at the very bottom it lists a "Brother 2". If this is not the correct way of checking on what you suggested please provide proper instructions. I'm not a Techie here so I appreciate your patience.

OK - That all looks good for the driver installation.

Does the device appear in the output of 'lsusb'?
Have you tried an alternative USB port? I recall a previous thread where a device that was plugged into a USB 3.0 port was failing, but was successful when plugged into a USB 2.0 port.

I've tried 3 different USB ports and still the same results.

Good - There is your device.
I am only seeing USB 1.1 and 2.0 hubs, so the USB 3.0 issue does not seem to apply.
Have you tried running 'sudo scanimage -L'? http://support.brother.com/g/s/id/li...ll&redirect=on

PS - Did you first uninstall the scan-key-tool before uninstalling the scanner drivers? http://support.brother.com/g/s/id/li...ll&redirect=on

Scan tool was uninstalled prior to driver installation. Just ire-installed scan tool..results:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Some thoughts:
Are you confident that libsane is correctly installed in your Linux Mint 18? There have been reports of some problems. http://blog.linuxmint.com/?p=3068
Are the Brother libraries present?
Is there an appropriate entry for your device in your "/lib/udev/rules.d/40-libsane.rules" file?
If not, you could add a local rule by creating a file called "40-libsane.rules" in the /etc/udev/rules.d/ directory containing the following:

40-libsane.rules File
 

Fairly certain that libsane was installed correctly. One thing that may be a issue, and I am not certain, but from what I have been reading, sane project does not support the MFC-440CN scanner. Below is the terminal command results:

dbrew4@dbrew4-Inspiron-546 ~ $ ls /usr/lib{,64}/sane/* | grep "libsane-brother"
ls: cannot access '/usr/lib/sane/*': No such file or directory
/usr/lib64/sane/libsane-brother2.so
/usr/lib64/sane/libsane-brother2.so.1
/usr/lib64/sane/libsane-brother2.so.1.0.7

Attached is the 40-lbsane.rules file and no Brother MFC-440CN scanner is listed but there is a note about Brother and other scanners that were not listed.

Don't quite understand "If not, you could add a local rule by creating a file called "40-libsane.rules" in the /etc/udev/rules.d/ directory containing the following:" There already is a file with that name under that directory as per the attached. I'm not sure I know how to create this file if necessary. Detailed instructions would help. Thanks for your patience.

Good - The Brother libraries are present.

Hmm - No entries for Brother in your /etc/udev/rules.d/40-libsane.rules file.
Seems odd. The idea is that there is a /lib/udev/rules.d/ directory that contains files with a general set of udev rules. This can be be overridden by adding entries in the /etc/udev/rules.d/ directory to suit local configuration. Your file seems overly long and repetitive.
From 'man udev'
I do not use Linux Mint, but to bastardise L.P.Hartley, "Linux Mint is a foreign distro: they do things differently there."

Thanks for your perseverance.

Tried entering first command under your Code: ...results

dbrew4@dbrew4-Inspiron-546 ~ $ sudo echo '# Brother MFC-440CN' >> /etc/udev/rules.d/40-libsane.rules
bash: /etc/udev/rules.d/40-libsane.rules: Permission denied

Did I do this correctly?

Err - probably my bad.
Can you use a text editor to add those lines in post#8 to the file?

Modified File
 

I modified the file as per attached but did not replace the original yet. It this correct?

The file is saved in a temp folder on my desktop but the original file is "40-libsane.rules" and the modified file is "40-libsane.txt"...different format? I modified it in Libre Office Writer but maybe not the correct file extension used.

Please find attached my suggestion. I have moved the lines up in the text.

Edit - When using LQ, text files can get an additional .txt extension. Maintain the "40-libsane.rules" filename.
