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.

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].

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].

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).

When the aligned copies are brought to the stapling position by the positioning
roller and jogger fences, the staple hammer motor [A] starts stapling.
During stapling, the stapler trims off the excess length [B] of the staples by lowering
the cutter [C]. This excess length depends on the number of copies in the set;
there will be very little for a stack containing 100 sheets. The staple waste drops
into the tray [D] in the stapler. When the stapler unit returns to its home position,
the tray hits the shaft [E] and the tray opens. The staple waste drops into the staple
waste hopper [F]. When the staple waste hopper is full, the actuator on its base
activates the staple waste hopper sensor [G]. An SC is displayed.

When a staple end or no cartridge condition is det ected, a message is displayed
advising the operator to install a staple cartridge. If this condition is detected during
a copy job, the indication will appear, and the copy job will stop.
The staple cartridge has a clinch area [D], in which jammed staples are left.
Operators can remove the jammed staples from this area.
When the operator lifts the release lever [E], the clinch area is released from the
cartridge by pushing the holders [F]. The jammed staples can be removed.
The staple sheet can be feed manually by sliding the knob [G].

After the copies have been stapled, the stack feed-out motor [A] starts. The pawl
[B] on the stack feed-out belt [C] transports the set of stapled copies up and feeds
it to the shift tray exit roller [D]. When stapling starts, the exit guide motor [E] opens
the upper exit guide [F], which includes the upper shift tray exit roller [G], in order to
feed out the leading edge of the copy set smoothly. The exit guide motor turns on
again a certain time after stapling is complete, and the upper exit guide plate is
lowered. Then the shift tray exit roller takes over the stack feed-out.
The on-off timing of the exit guide motor is detected by the exit guide open sensor
[H].
The stack-feed-out motor turns off when the pawl actuates the stack feed-out belt
home position sensor [I].

The shift tray lift motor [A] controls the vertical position of the shift tray [B] through
gears and timing belts [C]. When the main switch is turned on, the tray is initialized
at the upper position. The tray is moved up until stack height sensor 1 [D] is deÂactuated.
In sort/stack mode, if stack height sensor 2 [E] is actuated for 2 seconds, the shift
tray lift motor lowers the shift tray for 20 ms.
In staple mode, when the pawl on the stack feed-out belt reaches the upper
position of the staple unit, the shift tray lift motor lowers the shift tray for 400 ms
and stops for 200 ms. Then, it lifts the shift tray until stack height sensor 1 is deÂactuated by the feeler [F]. This means the tray lowers earlier in staple mode, to
prevent the next copy suddenly exceeding the space currently available on the
tray.
For both modes, the shift tray will rise until stack height sensor 1 is de-actuated
when the user takes the stack of paper from the shift tray.
This machine has two shift tray lower limit sensors 1 [G], 2 [H]. Shift tray lower limit
sensor 1 detects the near lower limit and sensor 2 detects the lower limit. When the
actuator [I] enters sensor 1, a message will be displayed and copying will continue.
When the actuator enters sensor 2, a message will be displayed and copying will
stop.
Options
The shift tray upper limit switch [J] prevents the drive gear from being damaged if
stack height sensor 1 fails. When the shift tray pushes up the shift tray positioning
roller [K], the switch will cut the power to the shift tray lift motor.

In sort/stack mode, the shift tray [A] moves from side to side to separate the sets of
copies.
The horizontal position of the shift tray is controlled by the shift motor [B] and shift
gear disk [C]. After one set of copies is made and delivered to the shift tray, the
shift motor turns on, driving the shift gear disk and the shaft [D]. The end fence [E]
is positioned by the shaft, creating the side-to-side movement.
When the shift gear disk has rotated 180 degrees (when the shift tray is fully shifted
across), the cut-out in the shift gear disk turns on the shift tray half-turn sensor [F]
and the shift motor stops. The next set of copies is then delivered. The motor turns
on, repeating the same process and moving the tray back to the previous position.

The punch unit is driven by the punch motor [A]. The punch motor turns on 78 ms
after the trailing edge of the pape r passes through the entrance sensor [B], and
makes the punch holes.
The home position is detected by the punch HP sensor [C]. When the cut-out in the
