 When the tray is pushed into the machine, the tray lift motor [A]
turns on and rotates a coupling [B] interlocked with a pin [C].
 This rotates the lift shaft [D] and operates the wire pulleys [E] that
raise the tray.
 The lift motor coupling remains locked with the pin (to keep the
stack raised), but when the tray is opened it disengages from the
arm and automatically lowers the bottom plate and stack.
