Head FFC
 When you do not need to replace the Head FFC, be careful not to disconnect it from the connector on the CR Encoder. Once it is disconnected, you must
disassemble the CR Unit to reconnect it to the CR Encoder.
 Confirm that the Head FFC is connected to the Holder Board Assy and CR Encoder.
 When routing the Head FFC on the side of the CR Unit, make sure to route it through the ribs (x3) of the CR Unit shown above.
 When routing the Head FFC on the Front Frame, first install the Head FFC Holder to the Front Frame Assy, and then route the Head FFC through the ribs
(x4) of the Front Frame.
 After routing the Head FFC on the CR Unit and Front Frame Assy, secure the ferrite core to the Front Frame Assy on the position shown above with
double-sided tape.
 Secure the grounding wire to the Front Frame Assy with the screw.
