4.7.3 MAIN Board (C472 MAIN)

CAUTION When disconnecting or connecting the connector for an FFC cable on the Main Board, never pull or push the connector aslant.

Disconnecting or connecting the connector can cause damage to, short circuit or breakage of the terminals inside the connector, thus

resulting in damage to elements on the circuit board.

1.Remove the Rear Cover. (p.166)

2.Disconnect all the harness connectors from the Main Board.

3.Remove the two screws (CP(W): M3⋅6) securing the both ends of the parallel interface

connector to the Main Board and seven other screws (CP(W): M3⋅6), and remove Main Board.

Screws (CP(W): M3⋅6) ⋅ 9

ADJUSTMENT REQUIRED

Refer to the table on the next page for connections of connectors. The following connectors are not used:

CN4, CN7, CN12, CN18, CN25, CN28, CN33, CN36, CN37

Before and after replacing the Main Board with a new one, make the following adjustment:

Refer to “5.1.4.2 Main Board Adjustment” (p.213)
