I run wireless test and all is fine, I can print and copy.  However everyday I have to turn the printer off and on to get it to print.  When I used the printer it scanned just fine.  Now I get the rrror message  "Unable to Communicate with the Scanner"

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,

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