1. Install the proof tray auxiliary plate.
    • Set the plate [A] in the center aligned with the diagonal groove.
    • The back should be flat against the end fence.
  2. When the plate is not being used, open the front door and store the plate at [B] inside the inner cover.
    • The plate should be used when Z-folded paper (all sizes) is output to the proof tray.
    • If the plate is not used with Z-folded output, the pages could mix and overlap.
