2. Remove the top panel assembly.
(Refer to Section 1-4-1.)
3. Loosen the screw with drop safe that is fixing the
manual ejection cover, and remove the manual ejection
cover.
4. Turn the gear (black) in the direction of arrow [1] until
it stops.
m
.Turn the gear (black) slowly without applying too
much force. Do not turn the gear beyond the place
where it stops.
.If the gear (black) cannot be turned, the loader
(P200) assembly may be defective. Refer to “1-5-2.
Manual ejection when the gear is broken” described
later, and take out the cartridge.
5. Turn the gear (black) in the direction of arrow [2], and
take out the cartridge.

1-5-2. Manual Ejection when the Gear is
Broken
If the gear (black) for manual ejection does not turn, the
loader (P200) assembly may be defective.
Eject the cartridge in the following steps.
1. Remove the top panel assembly.
(Refer to Section 1-4-1.)
2. Remove the four screws, and remove the stay sub
(upper) assembly.
Top cover (A) assembly
Screw with drop-safe
3. Loosen the two screws with drop safe that are fixing
the top cover (A) assembly.
4. Remove the top cover (A) assembly in the direction of
the arrow.

5. Release the lock by sliding portion A of connector
CN1 on the SE-852 board as shown in the figure with
tweezers or another tool, and disconnect the flexible
card wire.
m
.Life of flexible card wire will be significantly
shortened if it is folded. Be very careful not to fold
it.
.When reinstalling the removed parts, be careful not
to break the locking claws of the connector CN1 of
the SE-852 board.
6. Loosen the two screws with drop-safe on the loader
(P200) assembly.
7. Remove the loader (P200) assembly from the rear side
in the direction of the arrow.
m
.Stepped shafts are inserted into the loader (P200)
assembly on both sides of the front. Remove the
loader (P200) assembly after slightly pulling it
toward the rear.
.The spindle motor has an intense powerful magnet.
A part of the loader (P200) assembly may be
attracted by the magnetic force or hooked on the
edge of the spindle motor. Be careful when remov-
ing the loader (P200) assembly.
