2.6 SHIFT TRAY UP/DOWN MECHANISM
[G]
[H]
The shift tray lift motor [A] controls the vertical position of the shift tray [B]
through the gears [C,D]. When the main switch is turned on, the tray is
initialized at the upper position. The trays upper position is detected when the
shift tray pushes up actuator feeler[E] until the actuator turns on the stack
height sensor [F]. Then, the shift tray lift motor will turn in the reverse
direction until the stack height sensor turns off.
During copying, the actuator feeler [E] will gradually rise as the copy stack
grows. When the stack height sensor [F] turns on, the shift tray lift motor will
lower the shift tray [B] until the sensor is turned off.
When the actuator [G] turns off the lower limit sensor [H], the copying
process will stop. After the copying process ends, the machine had stopped
and the copies are removed, the shift tray will rise until the stack height
sensor [F] is turned on. Then, the shift tray lift motor will turn in the reverse
direction until the stack height sensor turned off.
