Shift Tray
Overview
• The shift tray lift motor [A] controls the vertical position of the shift tray [B] through gears and timing
belts [C].
• After the main switch is turned on, or when the stack is removed from the tray, the end of the feeler
on the tray falls and its actuator [D] rotates up into staple mode HP sensor 2 [E] (S7) and switches it
on.
• This switches on the lift motor, which raises the tray until the tray pushes the actuator out of the
sensor [E]. Then, the lift motor stops the shift tray; this is the home position (the actuator [D] is
between the two sensors [E] and [F].
• The shift tray upper limit switch (SW1) prevents the drive gear from being damaged if staple mode
HP sensor 2 [E] fails. In case of a failure, when the shift tray pushes up the actuator [G] and
positioning rollers, the switch will cut the power to the shift tray lift motor.
