CWIS > Properties > Security >Display Network Settings >Hide Network information Will remove it from the upper left of the screen
At this point though, the Machine status screen will still display it just fine, so you need to go to the printer, login as admin and then set the following 2 settings.
Machine Status > Tools > Authentication/Security Settings > Access Control > Device Access and set the Machine status Pathway to Locked and save that.
Then go to Machine Status > Tools > Authentication/Security settings > Login Type > Login to Local accounts.
Then save that and logout, after the reboot you will be required to login as the admin to get to the Machine status screen and therefore you will not be able to see any network settings as a guest user.
