￿Part/Unit that should be removed before removing Circuit board Housing (Right/Left/Frame) / ASF unit

￿Removal procedure

1)Remove Clamp core from [Mounting Plate, M/B], and disconnect the following seven cables from the corresponding connectors on main board.

- CR motor connector cable

: CN5

- PF motor connector cable

: CN6

- Head FFC

: CN7, CN8

- PE sensor cable

: CN9

- Power supply connect cable

: CN2

- Panel board connector cable

: CN4

2)Remove four screws for securing Circuit board to main frame, and remove the board.

3)Remove [Shield Plate, M/B] from main board.

￿When assembling Circuit board,

￿Make sure that the metal fittings for locking the Parallel interface is on its shield plate.

￿When assembling Circuit board to main frame,

￿Make sure to connect all cables to the connectors (CN2, CN4, CN5, CN6, CN7, CN8, CN9) on main board in the correct direction.

￿Fasten four screws for securing Circuit board in the order/tightening torque indicated in the figure.

￿Make sure that Shield plate FFC on Head FFC is securely pasted on [Mounting Plate, M/B].

￿Make sure that two dowels of Clamp core is set in home position direction.

￿Make sure that PE sensor cable & CR motor connector cable are set on Holder shaft unit, and in Clamp core.
