Install the Tower Tray Unit.

To install the Tower Tray Unit, you need the Tower Tray Connector (TC-4000).
Follow the steps below.

  • The Tower Tray Unit can be installed only when the Lower Tray Unit is NOT installed to the machine.
  • For MFC/DCP users
    • Be careful not to pinch your fingers when you put the machine down. DO NOT carry the machine with the Lower Tray Unit installed. You may be injured or cause damage to the machine because the Lower Tray Unit is not securely attached to the machine.
