88 Clearing Jams
Between three trays This type of jam may occur if you are using legal-size paper in the
trays or if you have a 250-sheet drawer installed with other optional
drawers.
1 Pull the paper tray out of the support unit. If only a short piece
of the paper is visible, do not pull down to remove the paper.
2 Gently slide the paper tray back into the support unit.
3 Pull the paper tray out of the support unit that is above the tray
you just pulled out and closed.
