If you cannot connect your Brother printer to Wi-Fi, please ask help from the printer manufacturer. usr/lib64/sane/libsane-brother3.so.1.0.Note: The connection process may vary from printers to printers. 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

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?

Which outputs: udp_command: No data received (select): timed out In the terminal, I enter the command: scanimage -list-devices How can I regain network access for scanning on my Brother all-in-ones? 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.

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.
