Is this printer networked? Log onto the web interface page and on the Print tab click Manage trays, be sure Tray 1 is set to Any Size and Any type, the other trays should be set to Letter and Plain unless you have other uses for them. Also set "Use Requested tray" to Exclusively and set Manually Feed Prompt to "Unless Loaded" and it should automatically print from Tray 1.
