Organizations conduct vulnerability assessments for their networks to identify the existing vulnerabilities, weaknesses, and loopholes. usr/lib64/sane/libsane-brother3.so.1.0.Updated On 6 March, 2023 Top 5 open-source tools for network vulnerability scanning I enter the command: dpkg -L brscan3, which outputs the following, copied to include only files in /usr/lib64: /usr/lib64 It seems I'm a step closer to the solution, but the MFC-7840W device ( brother3:net1 dev0) is still not working. Which outputs: scanimage: open of device brother3:net1 dev0 failed: Invalid argument
LINUX NETWORK SCANNER UPDATE
UPDATE 1: Based on comments, I copied the files libsane-brother* and libbrscandec* to the folders /usr/lib/sane and /usr/lib. What could/should I do to gain access to my Brother MFC-7840W network scanner?

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.
LINUX NETWORK SCANNER SOFTWARE
There have been some recent OS auto-updates and I've installed/un-installed several software programs. Now, network printing works on the MFC-9840CDW, but does not work on the MFC-7840W, and network scanning does not work on either.
Network access used to work for printing and scanning for both units. USB works for printing and scanning for both. The operating system is Ubuntu 14.04 LTS on a x86_64 system. I have two network/USB all-in-ones that are in separate networks, Brother MFC-7840W and Brother MFC-9840CDW.
