SECTION 1
DISASSEMBLY
1.3 Disassembly/assembly method
1.1 Disassembly flow chart
This flowchart lists the disassembling steps for the cabinet
parts and P.C. boards in order to gain access to item(s)
to be serviced. When reassembling, perform the step(s) in
reverse order. Bend, route and dress the flat cables as they
were originally laid.
1.2 How to read the disassembly and assembly
<Note 2a>
· Be careful not to damage the connector and wire etc. during connec-
tion and disconnection. When connecting the wire to the connector, be
careful with the wire direction.
<Note 2b>
· When reattaching the Front panel assembly, make sure that the door
opener "a" of the Cassette housing assembly is lowered in position
prior to the reinstallation.
<Note 3a>
· When installing the Cassette housing assembly, make sure that the
Control cam and the Main deck alignment holes are aligned. if they
are not, rotate the Loading motor belt to the front align the holes.
· When installing the Cassette housing assembly, be careful not to dam-
age the parts of the Main board and Mechanism assemblies.
<Note 5a>
· When removing the Mechanism assembly only, unhook the two spacers
connecting it with the Main board assembly with pliers from the back
side of the Main board assembly first, and then remove the Mecha-
nism assembly.
· When reattaching the Mechanism assembly to the Main board as-
sembly, take care not to damage the sensors on the Main board as-
sembly.
