Gear Alignment (Concepts, Procedure and Testing)
The CD Mechanism gear alignment is grouped into functional names for ease of use:
1. Stacker Height Rotary Encoder (1) Alignment
2. Disc Entry Lockout Gear Alignment
3. Clamping Motor Rotary Encoder (2) Alignment
4. Disc to Stacker Gear Alignment
Stacker Height Rotary Encoder (1) Alignment
Concept: To ensure the rear disc storage tray (stacker) is positioned at the correct height to accept discs, two
gears must be aligned (Figure 8-7).
Procedure: Prealign the black rotary encoder gear as shown in Figure 8-8. Place the Stacker tray on the 3-
stacker tray screws (Figure 8-9). You will have to rotate the screws to accept the stacker and drop the stacker in
place (this is above the top tray 5 position). Lastly, in Figure 8-9 place the large stacker (communications) gear
in place.
