      Depending on the finishing mode, the copies are directed up, straight through, or down by the combination of the tray junction gate [A] and stapler junction gate . These gates are controlled by the tray junction gate solenoid [C] and stapler junction gate solenoid [D].
      
      Upper Tray Mode
      The tray junction gate solenoid remains off. The copies go up to the upper tray.
      
      Sort/Stack Mode
      The tray junction gate solenoid turns on and the stapler junction gate solenoid remains off. The copies are sent to the lower tray directly.
      
      Staple Mode
      The tray junction gate solenoid and the stapler junction gate solenoid both turn on. The copies go down to the jogger unit.

      [D]
      
      [E]
      
      The vertical position of the lower tray [A] depends on the height of the copied paper stack on the lower tray. The stack height sensor feeler contacts the top of the stack, and the lower tray lift motor [C] controls the tray height.
      When the lower tray reaches its lowest possible position, the actuator [D] turns on the lower tray lower limit sensor [E], and copying stops.
      
      Tray Up
      When the copy paper on the tray is removed, the stack height sensor [F] turns off and the tray lifts up. Then, the tray stops when the sensor turns on again (the tray pushes up the feeler).
      If the stack height sensor fails, the lower tray upper limit switch [G] detects the tray and stops the motor. This is a safety measure against stack height sensor failure.
      
      Sort/Stack Mode (Tray Down)
      Every five sheets of paper, the tray goes down until the sensor turns off again. Then, it goes up until the sensor is on again.
      
      Staple Mode (Tray Down)
      After a stapled copy is fed out, the tray goes up for 220 ms and stops for 300 ms. Then, it goes down for 1 second, waits for 500 ms, then goes up until the sensor turns on.

      In the sort/stack mode, the shift roller [A] moves from side to side to separate the sets of copies.
      The horizontal position of the shift roller is controlled by the shift motor and the shift gear disk [C]. After the trailing edge of the copy passes the upper transport roller, the shift motor turns on, driving the shift gear disk and the link [D].
      After the paper is delivered to the lower tray [E], the shift roller moves to its home position, which is detected by the shift HP sensor [F]. Then, when the trailing edge of the next copy passes the upper transport roller, the shift roller shifts again. This operation is done every sheet.
      When the trailing edge of each page in the next set of copies passes the upper transport roller, the shift roller shifts in the opposite direction.

      In staple mode, each sheet of copy paper is vertically and horizontally aligned when it arrives in the jogger unit.
      For the vertical paper alignment, the positioning roller solenoid [A] turns on shortly after the stapler tray entrance sensor turns off, and the positioning roller [C] pushes the copy against the bottom of the stack stopper [D].
      For the horizontal paper alignment, the jogger front fence [E] and the rear fence [F] move to the waiting position, which is 18 mm away from the side of the paper.
      When aligning the paper vertically, the jogger fence moves in 14 mm from the waiting position. After the vertical position has been aligned, the jogger fence pushes the paper 4 mm against the rear fence to align the paper horizontally. Then the jogger fence moves back to the previous position.

      When stacking a large size of paper (such as A3, DLT) in the jogger unit, the leading edge of the paper reaches the exit rollers. To prevent the paper from running into the exit rollers and not being aligned correctly, the exit guide plate [A] is moved up to make a gap between the exit rollers. This operation is done for all paper sizes, but is only needed for the larger sizes.
      The exit guide plate motor and exit roller release cam [C] control the exit guide plate movement. When the exit guide plate motor starts, the cam turns and the exit guide plate moves up. When stapling is finished, the exit guide plate motor turns on again to close the exit guide plate. When the exit guide plate HP sensor [D] turns on, the motor stops.

      The staple hammer motor [A] drives the staple hammer.
      The staple sheet sensor detects the leading edge of the staple sheet at the stapling position to prevent the hammer from operating if there are no staples at the stapling position.
      If there is no staple cartridge in the stapler unit or no staples in the staple cartridge, staple end is indicated on the operation panel. The stapler sensor [C] detects this.
      The stapler rotation HP sensor [D] checks whether the staple hammer mechanism returns to home position after each stack has been stapled.
      When excessive load is applied to the staple hammer motor, the copier detects a staple jam. When a staple jam has occurred, the jammed staple is inside the staple cartridge [E]. Therefore, the jammed staple can be removed easily after pulling out the staple cartridge.

      The stapler motor moves the stapler [A] from side to side. After the start key is pressed, the stapler moves from its home position to the stapling position.
      If two-staple-position mode is selected, the stapler moves to the front stapling position first, then moves to the rear stapling position. However, for the next copy set, it staples in the reverse order (at the rear side first, then at the front side).
      After the job is completed, the stapler moves back to its home position. The stapler HP sensor detects this.

]



After the copies have been stapled, the stack feed-out motor [A] starts. The pawl

on the stack feed-out belt [C] transports the set of stapled copies up and feeds it to the shift roller. The shift roller takes over stack feed-out after the leading edge reaches this roller.

Just before the stapled stack passes through the lower tray exit sensor, the stack- feed-out motor turns off until the shift rollers have completely fed the stack out to the lower tray. Then, the stack-feed-out motor turns on again until the pawl actuates the stack feed-out belt home position sensor [D].
