Disc Entry Lockout Gear Alignment
Concept: This single gear alignment prevents another disc from being inserted by locking the entry roller guides
from moving when a disc is clamped.
Procedure: As in Figure 8-10 (mechanism bottom), rotate the Clamping motor gears until cam BU U/D is turned
fully clockwise. Insert the smaller cam (eject lock) gear with the mark as shown.
Test: The first disc entry rollers should be free to move (SW711 in Figure 8-7) Rotate the Chucking motor so the
Cam (BU U/D) is CCW (opposite Figure 8-10). The disc entry rollers should now be inhibited so they just move
enough to close SW711.
