Turn off the auto centering then put 11x17 paper in tray 5 and center the image if you go to the service mode and the centering is a large distance off 0 you may have to set the number to 0 then manually center the tray. Rember to set the lift lock so you can move the alignment gears while the tray is out. When you get it close you can use the service mode to bring it in closer I had to do this to one of my machines remember use 11x17 paper not 12x18 it does not work correctly.
