2.7 SHIFT TRAY MECHANISM

[A]
[F]
[B]
The guide gear [A] on which the shift tray is mounted is driven by the lift motor [B]
via gear [C].
The finisher board detects the direction of the motor rotation and motor position
using the lift motor sensors 1 [D] and 2 [E].
The lift motor contains a thermoswitch [F]. When it detects 73.5º C, the finisher
board stops the lift motor until its temperature reaches approximately 40º C.
The shutter position switch [G] cuts the lift motor power for safety when the upper
exit guide plate opens.
The shift tray height sensor [H] detects the distance between the sensor and the
top of the copy paper on the shift tray.
