We have setup for Scan to network buttons on the Dell C2665dnf.
UserA, UserB, UserC & UserD.UserA and UserB work with no issues. Graphically, UserA and UserB are on top and UserC & UserD are on bottom.
UserC & UserD do not work at all. These buttons are not selectable. If you touch them nothing happens. Whereas if you touch the buttons for UserA and UserB you get the green check mark.
Is there a setting that I am missing that could cause only the top 2 scan buttons to work?
