Can't get New Brother Laser printer/scanner to scan

[cybrsaylr]

brian got this:

~$ ls -l /usr/lib/sane/libsane-brother*
ls: cannot access '/usr/lib/sane/libsane-brother*': No such file or directory

~$ ls -l /usr/lib/x86_64-linux-gnu/sane/libsane-brother*
ls: cannot access '/usr/lib/x86_64-linux-gnu/sane/libsane-brother*': No such file or directory

Have contacted Brother and today they sent me a 'fix' that upon reading is more detailed, complex and complicated than the link shown in this thread by SeijiSensei in post 7!

It very much looks like you do not have the Brother scanner driver installed. Give me 5/10 minutes and I will describe what I would do.

Thanks brian.

Tried doing what was shown in the link shown in this thread by SeijiSensei in post 7 but couldn't figure it out!

• Go to https://support.brother.com/g/b/down...90dw_us&os=128 and select the 64bit scanner driver.

[list]Agree to the EULA and download brscan4-0.4.8-1.amd64.deb.

• Go to the directory holding brscan4-0.4.8-1.amd64.deb. and execute

  apt install ./brscan4-0.4.8-1.amd64.deb

Do the previous ls -l... commands now give a positive output? Can you now scan?

brian get this now for your 2 codes:

Printer works on printing but still won't scan.

Printer works on printing but still won't scan.

To get one thing out of the way: printing and scanning are completely different processes. There is no connection between them. It doesn't help to think that way.

We need the output of

ls -l /usr/lib64/sane

[cybrsaylr]

brian here's that output:

~$ ls -l /usr/lib64/sane
total 196
lrwxrwxrwx 1 root root     37 Apr 25  2019 libsane-brother4.so -> /usr/lib64/sane/libsane-brother4.so.1
lrwxrwxrwx 1 root root     41 Apr 25  2019 libsane-brother4.so.1 -> /usr/lib64/sane/libsane-brother4.so.1.0.7
-rwxr-xr-x 1 root root 198360 Apr 25  2019 libsane-brother4.so.1.0.7

Yes I realize printing and scanning are completely different processes. At least the copy feature works fine which I believe functions much like scanning....i hope.

Brother seems completely unaware that Debian libsane1 does not look in /usr/lib64/sane for SANE drivers, yet it puts the there. So much for supporting Mint. Something drastic (and probably my last try):

cp /usr/lib64/sane/libsane-brother4* /usr/lib/x86_64-linux-gnu/sane/

I hope you have updated your installation, as advised.

My Ubuntu 18.04.3 LTS is always kept up to date.

Got this output for your (last try) code:

~$ cp /usr/lib64/sane/libsane-brother4* /usr/lib/x86_64-linux-gnu/sane/
cp: '/usr/lib64/sane/libsane-brother4.so' and '/usr/lib/x86_64-linux-gnu/sane/libsane-brother4.so' are the same file
cp: '/usr/lib64/sane/libsane-brother4.so.1' and '/usr/lib/x86_64-linux-gnu/sane/libsane-brother4.so.1' are the same file
cp: '/usr/lib64/sane/libsane-brother4.so.1.0.7' and '/usr/lib/x86_64-linux-gnu/sane/libsane-brother4.so.1.0.7' are the same file
