Note3a: When removing, be careful not to break the wire.
Note3b: When removing, be careful not to damage any part.
On removing, slightly open the front side so as to
shift it from the frame.
Note4: For disassembling method, refer to Fig. 1-4-1.
Note6a: When removing, be careful not to break the wire.
Note6b: Remove the board assembly (MAIN/MDA) and
mechanism assembly together.
Note6c: When installing, arrange the wire between the OP
block assembly and VF assembly.
Note7a: When removing, be careful neither to break the wire
nor to damage any part.
Note7b: For disassembling method, refer to Fig. 1-6-1.
Note8: Be careful not to get an electric shock during the
work.
Note9: When reassembling, carefully arrange the wire.
Note0a: When disassembling/reassembling, be careful not
to damage any part.
Note0b: When reassembling, set the bracket (top) as the VF
unit is pulled out, and secure the installation in order
of (L 0 a) and (L 0 b).
Note0c: For disassembling method, refer to Fig. 1-5-1.
Note=a: When disconnecting the connector, carefully handle
the FPC on the top of the connector.
Note=b: Disconnect the connector V last, because it is
positioned inside.
Note~: When reassembling, carefully locate the FPC so
that it is sandwiched between the mechanism
assembly and MAIN board assembly.
