2. DETAILED DESCRIPTIONS
2.1 BASIC OPERATION
2.1.1 NORMAL MODE AND SORT/STACK MODE
[F]
[E]
[A]
[C]
[B]
[D]
A834D500.WMF
Copies exiting the copier pass through the entrance guide plate [A]. The transport
roller will send copies either to the proof tray or to each bin, depending on the
selected mode.
During copying, all rollers in the sorter stapler transport the paper at a speed which
depends on the copier. When the trailing edge of the copy passes the fusing exit
sensor, the speed of the rollers changes to 600 mm/s. This makes enough time for
the jogger plate to square the stack of paper and to stack the paper smoothly into
the bins.
Normal (Proof) Mode
When the “Start” key is pressed, the transport motor [B] energizes to rota te the
transport rollers [C]. The transport rollers send copies to the proof tray directly.
Sort Mode
When sort mode is selected, the bin drive motor [D] energizes to rotate the helical
wheels. The helical wheels [E] rotate twice to move the top bin to the transport
roller position, then the first copy is delivered to the top bin.
After the first copy of the first original has been fed to the top bin, the bin drive
motor moves the bins up one step (the helical wheels rotate once) so that the
second copy of the first original will be delivered to the next bin.
The jogger plate [F] squares the copies after each copy has been fed to a bin. After
all the copies of the first original have been delivered to each bin, the sorter stapler
maintains its status (the bin drive motor does not rotate).
A834-6
Page 8
24 February, 1999 BASIC OPERATION
The first copy of the second original is delivered to the final bin that was used for
the first original, then the final bin descends one step. The bins descend each time
a copy of the second original is delivered.
The direction of motion of the bins alternates for each page of the original until the
copy run is finished.
Stack Mode
[A]
A834D501.WMF
When stack mode is selected, the top bin advances to the transport rolle r position
in the same way as in sort mode.
After the first copy is delivered to the top bin, the jogger plate [A] moves across to
square the copy. The jogger plate squares the copies after each copy has been fed
to a bin.
After one set of copies for the first original has been delivered to the top bin, the bin
drive motor moves the bins up one step. Then, one set of copies of the second
original will be delivered to the next bin.

[B]
A834D502.WMF
[A]
[C]
[D]
A834D503.WMF
Mechanism
The stapler is only available in sort mode.
When the jogger plate has squared the final set of copies, the grip arms [A] move
inside the front side frame and catch the paper. The grip assembly brings the
copies into the stapler [B], and the stapler staples the copies.
After stapling, the grip assembly [C] brings the stapled copies back to the bin and
releases the copies. Then the grip assembly goes back to the normal position. The
bin either advances or descends one step [D] (depending on whether the page is
an odd or even numbered page of the original).
When the final set of copies has been stapled, the bins go back to the standby
position.
There are two staple modes.
Automatic Stapling
In ADF mode, when staple mode is selected before pressing the “Start” key, copies
will be delivered to each bin and stapled automatically.
Manual Stapling
In platen cover mode, after the copies have been sorted into the bins, the staple
mode LED starts to blink. If the sort key is pressed while this LED is blinking, the
copies will be stapled.

2.1.3 BIN DRIVE MECHANISM
[E]
[D]
[C]
[A]
[B]
A834D504.WMF
The bin drive mechanism moves the bins up and down to receive copies.
There are four pins on each bin. Two pins fit into the slots [A] in both the front and
rear side frames; the pins slide up and down in these slots. The other two pins fit
into the slot in the helical wheels; as the helical wheels turn, these pins move up
and down, and the other pins move up and down in the slots at the other end of the
bin.
The bin drive motor [B] drives the helical wheels [C] through timing belts as shown.
When the motor rotates clockwise, the bins lift; when it rotates counterclockwise,
the bins lower. There is a wheel sensor [D] located under the actuator [E] on the
rear helical wheel; the actuator has a slot which detects when the helical wheel has
rotated once.
When the bins are advanced, the helical wheels rotate once for each step. As the
pitch of the spiral on the helical wheel is greater when the bins are at the stapling
and paper exit area than when the bins are elsewhere, the amount of bin shift is
greater when the bins are at the stapling and paper exit area. This leaves enough
space to staple and stack the copies. Also, this reduces the total machine height.

BASIC OPERATION 24 February, 1999
2.1.4 BIN HOME POSITION
[A]
A834D505.WMF
The bin home position sensor [A] ensures that the proof tray is lower than the
transport roller when the bins are in the home position.
When the main switch is turned on, the sorter stapler initializes itself to check
whether the component parts work or not. At this time, the bin drive motor raises
the bins for a few moments, then it lowers the bins until the bottom bin actuates the
bin home position sensor.

[B]
[C]
[E]
[D]
A834D506.WMF
[A]
The jogger motor [A] drives the jogger plate [B] through the timing belts [C].
The jogger is at home position when the actuator on the jogger plate goes into the
jogger home position sensor [D].
In standby mode, the jogger plate is at the home position. When the “Start” key is
pressed, the copier sends the paper size information to the sorter stapler.
In sort, staple, and stack modes, the jogger moves three times to square the stack
of paper. First, when the paper has been fed completely into the bin (at the proper
time after the copy has passed through the entrance sensor [E], depending on the
paper length), the jogger motor moves the jogger plate out of the jogger home
position. Then, the jogger motor drives the jogger plate to the width of the copy.
Finally, the jogger plate moves inward to push all the copies against the front side
frame, which squares the sheets of paper. Then the jogger plate returns to the
home position.

The grip assembly consists of the grip motor [A], the timing belt [B], the drive gear
[C], the grip home position sensor [D], and the cam gear [E].
The grip motor drives the cam gear through the timing belt and drive gear. Cam
gear rotation drives the mechanism that catches the copies and moves the grip
arm unit [F]. When the cam gear rotates clockwise one full turn, the grip arm moves
to catch the copies and returns to the home position to prepare for stapling. After
stapling, the cam gear rotates counterclockwise once so that the stapled copies go
back to the bin, and the cam gear returns to its home position.
When the cam pushes the roller [G] on the lever [H] and the lever pushes the grip
arm, the grip arm can catch the copies.
A pin [I] on the cam gear fits into the slot in the grip arm unit. So, when the cam
gear rotates, the slot moves the grip arm unit inward and outward.
The actuator [J] on the cam gear activates the grip home position sensor once
every rotation of the cam gear. This allows the sorter stapler to determine that the
cam gear has rotated once.

A834D510.WMF
The stapler motor [A] drives the staple hammer [B] using the gears [C] and the cam
[D].
The roller [E] feeds the staple sheets under the hammer.
When the grip unit brings the aligned copies to the staple position, the stapler
motor starts rotating and the copies are stapled. When the cam completes one
rotation, the staple hammer home position sensor [F] is deactuated and the stapler
motor stops.
When the stapler paper se nsor [G] in the grip assembly does not detect an y copies
under the hammer, the stapler motor does not rotate.
When the trailing edge of the last staple sheet passes through the staple end
sensor [H], the sorter stapler enters the staple near end condition. After the current
job is completed, the Add Staples indicator lights on the operation panel. Then the
copier cannot be used whenever the staple mode is selected.

2.1.8 STAPLER SWITCH
[A]
[B]
A834D511.WMF
The stapler switch [A] below the grip assembly cuts the dc +24 V supply to the
stapler. In proof mode, all bins lower and push the lever [B]. This opens the stapler
switch so that the signal to the stapler is cut. In sort and staple modes, all bins are
advanced and the switch is closed so that the signal can be supplied to the stapler.
Staple Mode Disabling Conditions
1. Under the following conditions, staple mode is disabled.
•
If there is paper in a bin before the main switch is turned on.
•
If the selected paper size does not match the stapling specifications.
•
If the paper is fed from the by-pass feed table.
•
If the stack or interrupt modes are selected.
2. Under the following conditions, staple mode is canceled if it had been selected.
•
If paper is inserted into a bin by hand while the staple mode is selected.
•
If only one sheet is delivered to the bin.
•
If the number of sheets to be stapled exceeds the stapler capacity.
