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 stapler tray junction gate solenoid remains off and 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 stapler junction gate solenoid turns on. The copies go downwards to the jogger unit.

[B]
[E] [F]
[C]
[D]
B302D000.WMF
This mechanism improves productivity in staple mode. It is only used when copying on A4, LT, or B5 (all sideways).
During stapling, the copier has to wait. This mechanism reduces the wait by holding the first two sheets of a job while the previous job is still being stapled. It only works during the second and subsequent sets of a multi-set copy job.
The pre-stack junction gate solenoid [A] turns on about 230 ms after the 1st sheet of paper turns on the entrance sensor, and this directs the sheet to the pre-stack tray [B]. (This sheet cannot be fed to the stapler yet, because the first set is still being stapled.) The pre-stack paper stopper solenoid [C] turns on about 680 ms after the 1st sheet turns on the entrance sensor. The pre-stack paper stopper [D] then stops the paper.
The pre-stack junction gate solenoid turns off 450 ms after the trailing edge of the 1st sheet passes through the entrance sensor, and the 2nd sheet is sent to the paper guide [E]. The pre-stack paper stopper is released about 50 ms after the 2nd sheet turns on the pre-stack stopper sensor [F], and the two sheets of copy paper are sent to the stapler tray. All sheets after the 2nd sheet go to the stapler tray via the paper guide [E].

B302D508.WMF
In staple mode, each sheet of copy paper is vertically and horizontally aligned when it arrives in the jogger unit.
Vertical Paper Alignment
Approximately 60 ms after the trailing ed ge of the copy passes the staple tray entrance sensor [A], the positioning roller solenoid [B] is energized 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 prin t key is pressed, the jogger motor [F] turns on and the jogger fences [G] move to the waiting position, which is approximately 7 mm wider on both sides than the selected paper.
When the tr ailing edge of the paper passes the staple unit entra nce sensor, the jogger motor turns on for approximately 32 ms (4.7 mm) to move the jogger fences approximately 5 mm towards the paper. After a short time, the jogger motor turns on again approximately 18 ms (3.0 mm) for the horizontal paper alignment then goes back to the waiting position.
Paper Stack Correction
After the paper is aligned in the stapler tray, the stack plate motor turns [H] on for short time to correct the paper stack and the stack plate [I] push the paper against the staple tray.
When the next copy pape r turns on the s tapler tray entrance sensor, the stack plate motor turns on gain to return to its home position. The home position is detected by stack plate HP sensor [J].

STAPLER UNIT MOVEMENT 22 October 1999

2.4 STAPLER UNIT MOVEMENT

[A] [B]

B302D513.WMF
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].

Rotation (1)
In the oblique staple position mode, the stapler rotation motor [A] rotates the stapler units [B] 45° to counterclockwise after it moves to the stapling position.
Rotation (2)
When the s taple end cond ition arises, the stapler motor moves the stapler to the front and the stapler rotation motor rotates the stapler unit to clockwise to remove the staple cartridge [C]. This allows the user to add new staples.
Once the staples have been installed, and the front door closed, the stapler unit returns to its home position. As the stapler unit is returning to the home position, the stapler return sensor [D] is activated, the return solenoid [E] turns on and it assists the guide roller [F] to return to its guide (this guide directs the stapler during rotation).
