Although Brother Printers are quite commendable and pretty great, they are not without fault, which is why users of Brother Printers have been suffering from a multitude of different problems over the course of time. One of the most common and most severe problems that Brother printer users have suffered from and continue to be affected by is their wireless printers not being detected and recognized by their computer and not showing up in ControlCenter4 (the resident suite for Brother Printers) even though they both the computer and the printer are connected to one another wirelessly. Since the printer is not detected by the computer, the user cannot print, scan or photocopy anything as their computer fails to communicate with their printer, rendering their printer pretty much unusable.
In such cases, users receive an error the states the (model number of printer) LAN cannot be found. This problem can be caused by anything from security issues to corrupted registry keys or entries that have been created after a Windows update. This issue is most commonly known to affect users of the Brother MFC-7860DW wireless printer but can basically affect any and all printers manufactured by Brother. Fortunately though, fixing this problem and getting your computer to successfully detect, display and communicate with your Brother printer is pretty simple and easy. The following are the two most effective solutions that you can use to fix whatever issue is causing your Brother printer to not be displayed in ControlCenter4 and not work:
Method 1: Clear all twain, twunk and .mtx files in the Temp folder
Hold Windows Key and Press R. In the Run Dialog, type %temp% and Click OK.
Locate and delete any and all files in the Temp folder that have the terms twain or twunk in their names or have .mtx as their file extension. Examples of such files include log, twain001.mtx, twunk001.mtx and twunk002.mtx.
Once you have deleted all such files, restart your computer and your Brother printer should not only be detected but should also start working once your computer powers up.
Method 2: Clean your computer’s registry using CCleaner
If Method 1 does not work for you and does not lead to your Brother printer being successfully detected, a scenario which is quite unlikely, another solution that has proven to work for countless Windows users who have been affected by this issue is using CCleaner to clean up the affected computer’s registry.
