Scanning on Brother MFC-L2740DW

[penman131]

Recently I changed the address of my local lan (192.168.xxx.xxx), and now, while I can still print ok, my scanning software cannot find the printer.
Could someone let me know where I have to look to change the scanner parameters in order to restore that function.

Step 5. Setting for your network scanner
***Use brsaneconfig (for brscan models), brsaneconfig2 (for brscan2 models), brsaneconfig3 (for brscan3 models) or brsaneconfig4 (for brscan4 models) accordingly.
5-1. Add network scanner entry

Command : brsaneconfig2 -a name=(name your device) model=(model name) ip=xx.xx.xx.xx
Example

5-2. Confirm network scanner entry

Command : brsaneconfig2 -q | grep (name of your device)

Use the version of brsaneconfig installed on your system.

Good Luck

Settings for address can be changed at usr/local/brother/sane and open brsanenetdevice3.cfg. Just change the address and save the file, should be able to scan without issue.

What Ubuntu version? I'm having no luck getting either a Brother MFC-6490CW or Samsung ML-2870 (I think) recognized in 17.10. I've tried all the fixes I can find and no luck so far. Both devices work without issue in 16.04.

No such directory as /usr/local/brother (/sane)

I managed to fix the issue. The file in question was: /etc/opt/brother/scanner/brscan4/brsanenetdevice4.cfg It had the old IP in it, just waiting to be changed !

Thanks for the clue Gifford.

Thanks to all who contributed to the solution. I recently reconfigured my network, and as a result, had to reconfigure the printers and scanner on several machines. This thread helped immensely; I probably would never have located the proper directory. My brsanenetdevice4.cfg was empty so I ran brsaneconfig4* in order to populate the brsanenetdevice4.cfg file.
Here is a list of the folder contents where the executable and configuration file reside...
