Hello,

 

Have you tried to test and see if Webroot is causing this issue?

 

That is the first step I would advise taking.

 

Basically Uninstall Webroot, reboot the machine, and then test to see if you can scan now.



If you are still experiencing the issue then we know Webroot is not the cause.



If you are not experiencing it any longer, go ahead and reinstall Webroot and let me know if everything is working afterwards.



Regards,

Hi jhawley,

 

This is not an uncommon problem.  I know there are a lot of complaints regarding Brother but I have had the same experienced with HP and Canon also.  Just do a search using the following search terms "brother scanner pdf files too large" and you will find several posts, including posts from Brother support and even YouTube tutorials.

 

There are also quite a few apps (free and paid) and online sites that offer pdf compression services.  I have not used the online service but I have used the compression apps and they do work.   Even Adobe has an optimize function that can be used.

 

Good luck in solving this issue,

Dave
