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 [B].
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 turns on. The copies go up to the upper tray.
Sort/stack mode
The tray junction gate solenoid and the stapler junction gate solenoid remain off.
The copies are sent to the shift tray directly.
Staple mode
The tray junction gate solenoid remains off and the stapler junction gate solenoid
turns on. The copies go downwards to the jogger unit.

In staple mode, each sheet of copy paper is vertically and horizontally aligned
when it arrives in the jogger unit.
Vertical Paper Alignment
After the trailing edge of the copy passes the stapler tray entrance sensor [A], the
positioning roller solenoid [B] is energized for 280 ms to push the positioning roller
[C] into contact with the paper. The positioning roller and alignment brush roller [D]
rotate to push the paper back and align the trailing edge of the paper against the
stack stopper [E].
Horizontal Paper Alignment
When the print key is pressed, the jogger motor [F] turns on and the jogger fences
[G] move to the waiting position, which is 7 mm wider on both sides than the
selected paper.
When the trailing edge of the paper passes the staple unit entrance sensor, the
jogger motor turns on for approximately 70 ms to move the jogger fences 5 mm
towards the paper. After a short time, the jogger motor turns on again
approximately for 60 ms for the horizontal paper alignment then goes back to the
waiting position.

Side-to-side:
The stapler motor [A] moves the stapler [B] 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. This is
detected by the stapler HP sensor [C].
[D]
Rotation:
In the oblique staple position mode, the stapler rotation motor [D] rotates the
stapler 45° after it moves to the stapling position.
