Xerox 4260 copying pick up tray

When we run copy on our 4260 it will only pick up from the bypass tray so we have to leave that tray with paper in it. If we close the bypass tray, the copier will not pick up from the regular default tray. I have checked settings and found no where you can set the pick up tray when copying. Has anyone else experienced this or have any ideas?

Thanks in advance!
