Hi setart,
Thank you for using the Support Forum. Please take a look at the solution for Configuring or Modifing the Default Paper Tray to a Tray Other Than Auto Paper and see if that helps. Also take a look at the solution for setting tray priorities, this may also be causing the behavior you are seeing. If these solutions do not help please consider contacting your support centre for further assistance.
Auto select of paper will only copy from drawer 4. What should I do for auto pull form any drawer.
