[A]
[C]
Copies exiting the copier pass through the entrance guide plates [ A] to th e
turn gate section. The turn gate [B] will send copies either to the proof tray or
to the bins, depending on th e m od e.
- Normal mode - (from the turn gate section to the proof tray)
The turn gate solenoid [C] is energized and the turn gate turns clockwise
when the start key is pressed. The proof motor [D] rotates the vertical
transport rollers [E] and exit roller [F]. The turn gate directs copies through
the vertical transport section to the proof tray.
In this mode, if a misfeed is detecte d in the sor ter stapler, the proof motor
stops and the turn gate solenoid turns off. The main motor starts rotating.
Copies going through the copier are sent to th e 1st bin through the diagonal
transport, horizont al tr a nsp or t , an d distribution section.

[E]
The turn gate solenoid [A] stays off and the turn gate [B] also stays up when
the start key is pressed. The main motor [C] rotates the diagonal transport
rollers [D], horizontal transport rollers [E], and distribution rollers [F].
The turn gate directs copies to the diagonal transport section. The diagonal
transport section feeds copies diagonally. This is because copies are brought
to the front side in advance for easier jogging.
Copies are directed to the distribution section through the diagonal and
horizontal transport sectio n. The ap pr o pri a te bi n ga te [G] opens and copies
are delivered to each bin.
The jogger plate [H] then jogs to square the copies each time.
In this mode, if a misfeed is detected in the sorter stapler, the main motor
stops. The proof motor starts rotating and the turn gate solenoid energizes.
Copies going through the copier are directed to the proof tray.

When the final set of copies is jogged in the sort mode (figure 1), the staple
unit staples the stacked copies as follows:
The grippers (A) move forw ard , and grip the copies (figure 2). The grippers
bring the copies up underneath the stapler (figure 3). The stapler staples the
copies (figure 4). The copies ar e push ed back int o th e bin . The gr ipp ers open
and return to the home position. The staple unit moves to the next bin
(figure 5).
When the final set of copies is stapled, the staple unit is raised to the home
position.
There are two staple modes.
1) Automatic stapling:
In ADF mode, when the staple mode is selected before pressing the start
key, copies will be delivered to each bin and stapled automatically.
2) Manual stapling:
In sort mode, after copies are sorted in bins, the copies will be stapled
when the staple key is pressed. In stack mode, manual stapling is
impossible.

The distribution section has the distribution rollers [A], 20 bin ga te s, an d 19
bin gate solenoids (the 1st bin gate is always open).
When a bin gate solenoid [B] is off, the return spring [C] holds the bin gate [D]
out of the paper path, allowing the copies to pass to the upper bin.
The appropriate bin gate solenoid turns on and opens the bin gate. The other
solenoids are off. The copies go to the bin [E] through the gate.
To prevent copies from curling and so causing misstapling or wrong staple
positioning, the bin has paper flatteners [F] on the front side of the bin.

When the start key is pressed in the sort, stack, or staple mode, the copier
sends the paper size information to the sorter stapler unit. In accordance with
this data, the jogger motor [A] drives the jogger plate [B] from the jogger
home position to where the width is 10 mm wider than the selected paper.
After the trailing edge of a copy passes the jam sensor (the bin/jam sensor),
and after the appropriate timing [C] for the selected paper, the jogger motor
rotates and reverses. This makes the jogger plate push all the copies against
the bin side plate [D] to square the stack. Also, this makes the jogger plate
return to where the width is 10 mm wider than the selected paper for the next
copy.
When the bin sensor in the bin/ja m senso r det ect s tha t all cop i es are
removed from the bins after jogging is finished, th e jogger plate returns to its
home position.

[G]
The bin side plate [A] is always in the home position except during the staple
operation. The bin side plate takes part in the jogger function (see jogger
section).
In the staple mode when all the copies have been jogged by the jogger plate,
the bin side plate drive motor [B] rotates the cam drive plate [C]. The pin on
the cam drive plate raises and lowers the actu ator cam [D], and the actuator
cam makes the bin side plate [E] move to the front side. Thus, the bin side
plate does not interfer e with th e cop i es [F] bein g br o ug ht to th e sta ple
position by the grip assembly.
When the staple operatio n fo r the final set of copies is completed, the bin
side plate drive motor rotates th e cam drive pl at e un til the bin side plate
home position sensor [G] is actuated. This makes the bin side plate return to
the home position.

9.1 STAPLE UNIT DRIVE MECHANISM
[C]
[D]
[F]
The staple unit consists of the grip assembly [A] and the stapler [B]. The
staple unit is lowered from the home position (the first bin) to the 20th bin in
order to staple the copies in each bin. The grip assembly grips the copies
stacked in the bin and positions them underneath the stapler. The stapler
staples the copies.
[H]
[G]
[E]
[A]
[B]
When the first set of copies is stapled, the staple unit drive motor [C] drives
the staple unit downward via timin g pu lleys [D] , and timing belts[E]. While the
staple unit is being lowered, the staple unit position sensor [F] tracks the
position actuator plate [G], generating an on/off signa l t hat is sent to the
sorter stapler main control board. This way, the position of the staple unit is
detected and the staple unit drive motor stops the staple unit when it reaches
the next bin. When the last set of copies in the bin is stapled, the staple unit
drive motor reverses until the staple unit home position sensor [H] is
actuated. At this time, the staple unit is in the home position.
Because lifting the unit requires more torque than lowering it, the lifting speed
is about one third of the lowerin g spe ed .

When the bin side plate starts moving to the front side, the grip motor [A]
drives the grippers [B] into the bin. The grippers track the gripper guide [C].
The grip motor stops the grippers at the grip position. The grip solenoid [D] is
energized and it closes the grippers to grip copies in the bin. When the bin
side plate reaches the front side, the grip motor reverses and brings the
grippers with the copies to the staple position. The paper sensor [E] checks if
copies are brought to the staple position correctly. Then, the copies are
stapled, and the grip motor drives the grippers with the stapled copies back
into the bin.
When the grip solenoid turns off, the return spring [F] opens the grippers. The
copies remain in the bin. Then, the grippers return to the home position for
the next cycle.
The grip home position sensor [G] is actuated while the grippers move from
the home position [H] to the grip position [I]. This sensor is deactuated while
the grippers move from the home position to the staple position [J]. The
sorter stapler main control board sends the appropriate pulses to the grip
motor (stepper motor) to determine the grip position and staple position.
When the main switch is turned on, the grip motor turns forward and
backward to check whether the grip pe rs are in th e home position. If not, the
grip motor returns the grippers to their home position.

The stapler motor [A] drives the staple sheet drive belt [B].
The staple sheets are fed under the hammer [C].
The stapler motor drives the staple hammer via gears [D], two eccentric cams
[E], and two links [F].
When the aligned copies are brought to the staple position by the grippers,
the stapler motor starts rotating. When the cams complete one rotation, the
staple home position sensor [G] is deactuated. The stapler motor then stops.
When the paper sensor in the grip assembly does not detect that the copies
are under the hammer, the stapler motor does not rotate.
A paper sheet [H] with a notch cut-in is positioned at the bottom of the staple
cartridge. This paper sheet is fed out after the last staple sheet. When the
leading edge of the notch in the sheet is detected by the staple end sensor
[I], the sorter stapler unit recognizes the staple near end condition . Af ter the
job is completed, the Add Staple indicator lights on the copier operation panel
and the Start key turns to red whenever the staple mode is selected.

The sorter stapler main control board detects a staple error when the
following conditions are detected.
Error 1 The paper sensor in the grip assembly turns on (paper is still in
the grip assembly) while the staple unit is being lowered.
In this case, a staple error signal is sent to the copier. The copier
cancels the staple mode and indicates a staple error.
After paper left in the grippers is removed, the staple unit returns
to the home position. When the staple key is pressed, the stapler
begins to staple the rest of the copie s star t i ng fr om th e bin
following the bin where the jam happened.
Error 2 The paper sensor in the grip assembly does not turn on (paper is
not in the grip assembly) when the grippers are in the staple
position.
In this case, the staple unit skips stapling this bin and moves to
the next bin for stapling.

NOTE
15.2 REGULAR PM EXPLANATION
The diagonal transport rollers and/or the diagonal transport stopper become
dirty because of paper dust and toner adhering to them. This causes copies
to transport incorrectly, skew, and jam. Cleaning them is required at regular
intervals.
If the diagonal transport stopper mylar is deformed or damaged, copies
transport incorrectly, skew, and jam. In this case, replace the mylar.

- Possible Causes -
1. If a staple [A] jams inside the
staple bending gate [B], the gate
cannot close completely. Staples
are not crimped completely, and
there is about a 1 mm gap
between the staple and the paper
surface.
2. A bent staple prevents the staple
push plate [C] from moving
downward.
Another possibility is that the staple
sheet has not yet reached the
stapling position.
