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

NOTE: Illustrations shown below are from a representative product and operating system, and may differ from your Brother machine and operating system.

1. Remove the attachments from the Tower Tray Unit box.
   
    
2. Remove the packing materials and take out the AC cord (1) and brackets(2), (3), located in the top of the Tower Tray Unit.

4. Remove the packing materials surrounding the Tower Tray Unit.
   
    
5. Check the components of both the TT-4000 and TC-4000.
   Use only the parts illustrated in A and C. Do not use parts shown in B to set up the Connector.
   Be sure to use the black screws (1) included with the TC-4000 to attach the connector to your machine's base.
   
    
6. Place the Tower Tray Unit on a flat surface.
   
    
7. Rotate each of the support legs until all four touch the floor so that the Tower Tray will not move.

9. Remove the Paper Tray and the toner cartridge and drum unit assembly from the machine.

11. Remove the two pieces of orange packing material and discard them.
    Hold the blue handle of the waste toner box and remove the waste toner box from the machine.

    The orange packing pieces are installed at the factory to protect your machine during shipment.

    
     
12. Rotate the machine 180 degrees.
    Carefully place your Brother machine face down on a flat surface so you can access the bottom of the machine.
    
     
13. Securely attach the brackets to the machine's base using a screwdriver and the included screws.
    Be sure to use the black screws included with the TC-4000 to attach the connector to your machine's base.
    
     
14. Lift your machine, align the bracket holes with the four pins on the Tower Tray Unit, and carefully lower the machine into place.
     
     
15. Install the waste toner box back into the machine using the blue handle. Make sure the waste toner box is level and fits firmly into place.
     
     
16. Install the belt unit back into the machine. Make sure the belt unit is level and fits firmly into place.
     
     
17. Install the Paper Tray and the toner cartridge and drum unit assembly back into the machine.
