Thanks for the reply.  I went through the steps in the article and when I re-loaded the drivers everything worked fine.  I am using a Surface Pro 4 that is mobile.  When I leave the premises with it and it re-connects when I come back it does not work properly.  I have to turn the printer off and back on for the printer to work.  As of now the scanner also works.  Sometimes it does and some times not.  It's a pain to turn the printer off and on, any other ideas?

Thanks,

I got the same issue and I changed the Resolution to 300 ppi (I wanna use 600 ppi as default) then the problem has been solved. Please try and update if you can.

Thanks, but I use a Mac so that link was useless.
