Loading Motor

The rotation of the motor turns the three gears to its left. The final gear at the far-left mates with the teeth on the tray. Motor direction determines tray movement. Electrical feedback to stop the motor is an opened/closed electrical switch under the white activator arm. The tray at the end posi- tion pushes the arm.

Platform Position

When the loading motor drives the tray inward, a channel in the tray moves a spring-loaded pawl into the middle rotating gear. The gear’s rotation continues to slide this pawl to the left. The front part of this pawl that faces the laser assembly platform lifts a pin connected to the platform. As the pawl slides left, the platform is lifted up. The pawl in the tray’s channel prevents the tray from sliding out.

No Power Tray Removal – From the Bottom

A spring-loaded pawl under the tray locks the tray closed. The bottom part of this pawl can be accessed from under the mechanism assembly.

1.Unplug AC power and press the power button to discharge the power supply capacitors.

2.At the mechanism top, remove the two screws and the mechanism’s top cover. The cover acts as a tray stop. Cover removal allows the tray to be pulled out later.

3.At the rear of the mechanism remove the rear black screw for finger clearance.

4.Place your finger under the mechanism. Push the slider’s bottom tab.

5.At the bottom of the assembly, slide the tab toward the center of the mechanism. This lowers the laser (unchucks), freeing the tray.

6.From the top of the mechanism, slide the tray out
