LBP632CDW Manual Feed Tray not working

[TITO]

Brand new LBP632CDW  not printing from manual feed tray.   Paper pulls in correctly all the way into the printer.  Looks like settings ok but went printing a document, pulls from regular tray (which works ok).   Followed directions in manual but no clear solution seen to fix this problem.
