Copies exiting the copier pass thro ug h the entrance guide plates [A] to the
turn gate section. The turn gate [B] will send copies eith er to the proof tray or
to the bins, depending on the mod e.
- Normal mode - (from the turn gate section to the proo f tra y)
The turn gate solenoid [C] is energized and the turn gate turns clockwise
when the start key is pressed. The proo f mot or [D] ro ta te s the vertica l
transport rollers [E] and exit roller [F]. The turn ga te direct s copie s thro ug h
the vertical transport sect ion to th e proof tray.
In this mode, if a misfeed is detected in the sorter stapler, th e pro of moto r
stops and the turn gate sole no id turns off. The main moto r starts rotating.
Copies going through the copier are sent to the 1st bin through the diagonal
transport, horizo nt al transport, and distribu tio n section.

The turn gate solen oid [A] stays off and th e turn gate [B] also stays up when
the start key is pressed. The main motor [C] rotates the diagonal transport
rollers [D], horizontal transpo rt rolle rs [E] , and dist ribu tio n rolle rs [F].
The turn gate directs copies to the diagonal tran spo rt section. The diagonal
transport section fee ds cop ies dia go na lly. This is beca use copies are brought
to the front side in advan ce for easier jogging.
Copies are directed to the distrib ut ion section through the diagonal and
horizontal transp ort section. The appropriate bin ga te [G] opens and copies
are delivered to each bin.
The jogger plate [H] the n jog s to squ are the copies each time.
In this mode, if a misfeed is detected in the sorter stapler, the main mot or
stops. The proof motor sta rts rot at ing and the turn gate solenoid energizes.

When the final set of copies is jog ged in the sort mode (figure 1), the stap le
unit staples the stacked copies as follows:
The grippers (A) move forward, and grip the copies (f igu re 2). The grip pers
bring the copies up underneath the stapler (f igu re 3). The stapler staples the
copies (figure 4). The copies are pushed back into th e bin . The grippers open
and return to the home posit ion. The staple unit moves to th e next bin (figure
5).
When the final set of copies is sta ple d, the stap le unit is ra ised to th e home
position.

There are two staple modes.
1) Automatic stapling:
In ADF mode, when the staple mode is select ed before pressin g the start
key, copies will be delivered to each bin and sta ple d auto mat ically.
2) Manual stapling:
In sort mode, after copies are sort ed in bins, the copies will be stapled
when the staple key is pressed. In sta ck mode, manual stapling is
impossible.

When the start key is pressed in the sort, stack, or staple mode, the copier
sends the paper size informatio n to the sorte r stap ler un it. In acco rda nce with
this data, the jogger motor [A] drives th e jog ger 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 th e jam sen sor (th e bin /ja m sensor),
and after the appropriate timing [C] for the select ed paper, the jogg er mot or
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 pa pe r for the next
copy.
When the bin sensor in the bin/ja m sensor detects that all copies are
removed from the bins afte r jogg ing is fin ishe d, the jogg er pla te re tu rns to it s
home position.

- Jogger off conditions -
1. Under the following conditions, the jogger plate does not jog after copies
are delivered to the bins.
• If paper is loaded in a bin by hand while the sort/sta ck, or
staple mode is selected.
• If the selected pape r size doe s not ma tch stap ling
specifications.
• If copies of different width are delivere d to the bins.
2. If paper is in a bin before the main switch is turned on, the sort /st ack
mode is disabled when th e sort er key is p resse d.

The bin side plate [A] is alwa ys in the home posit ion except during the staple
operation. The bin side plate takes part in the jogger f un ctio n (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 at or cam [D], and the actuator
cam makes the bin side plate [E] move to the front side . Thus, the bin side
plate does not interf ere wit h th e copies [F] being brought to th e sta ple
position by the grip assembly.
When the staple operation for the final set of co pie s is completed, the bin
side plate drive motor rotates th e cam drive plat e until th e bin side pla te
home position sensor [ G] is act ua te d. This makes the bin side plate re tu rn to
the home position.

6. STAPLE UNIT
6.1 STAPLE UNIT DRIVE MECHANISM
10 July 1991
[C]
[D]
[F]
The staple unit consists of the grip assemb ly [A] and the stap ler [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 assemb ly grips th e cop ies
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 mot or [C] drives
the staple unit downward via timing pulleys [D], and timin g belts[ E] . While the
staple unit is being lowered , th e sta ple unit posit ion sensor [F] tracks the
position actuator plate [G], generating an on/off signal that is sent to the
sorter stapler main control board. This way, the posit ion of the staple unit is
detected and the staple unit drive moto r st ops t he stap le un it whe n it rea ches
the next bin. When the la st set of cop ies in the bin is stapled, the stap le un it
drive motor reverses until the sta ple unit home posit ion sensor [H] is
actuated. At this time, th e sta ple unit is in the home po sitio n.
Because lifting the unit req uire s mo re torque than lowering it, the lifting spe ed
is about one third of the lowering speed.

[A]
[I]
[G]
When the bin side plate sta rts movin g to the front side, the grip mo to r [ A]
drives the grippers [B] into the bin. The grippers track the grip per guide [C].
The grip motor stops the grippers at the grip position. The grip solen oid [D] is
energized and it closes the grippers to grip cop ies in th e bin . Whe n th e bin
side plate reaches th e front side, the grip motor reve rses an d 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 copie s are
stapled, and the grip motor drives the grippers with the sta ple d copies ba ck
into the bin .
When the grip solenoid turns off, the return spring [F] opens the grippers. The
copies remain in the bin. Then , th e grippers return to the home posit ion for
the next cycle.
The grip home position senso r [G] is actuated while the grippers move from
the home position [H] to the grip position [I]. This sensor is deactuate d while
the grippers move from the home position to the staple position [J]. The
sorter stapler main control board sends the approp riat e pulses to the grip
motor (stepper motor) to determine the grip position and sta ple posit ion .
When the main switch is turned on, the grip motor turns forwa rd an d
backward to check wheth er th e grippers are in the home positio n. If no t, the
grip motor returns the grippers to their home posit ion .

The stapler motor [A] drives the sta ple sheet drive belt [B].
The staple sheets are fed under th e hammer [C] .
The stapler motor drives th e sta ple hammer via gears [D], two eccentric ca ms
[E], and two links [F].
When the aligned copies are brought to the staple position by the grippers,
the stapler motor starts rot ating. When the cams complete one rotation, th e
staple home position sensor [G] is d eactuated. The stapler motor then stops.
When the paper sensor in the grip assembly does not detect that the copies
are under the hammer, th e sta pler 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 aft er th e last stap le she et . Whe n th e
leading edge of the not ch in the sheet is detecte d by the staple end senso r
[I], the sorter sta ple r unit recognizes the staple ne ar en d con dition. After the
job is completed, the Add Sta ple indicator lights on the cop ier operation panel
and the Start key turns to re d whe ne ver 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 lowere d.
In this case, a staple error sign al is sent to the copier. The copier
cancels the staple mode and indicates a staple error.
After paper left in th e grip pe rs is remo ved , the staple unit returns
to the home position. Whe n the staple key is pressed, th e stapler
begins to staple the rest of the copie s st art ing from 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 skip s stap ling this bin and moves to
the next bin for staplin g.

between the staple and the paper
surface.
2. A bent staple prevents the staple
push plate [C] from moving

sheet has not yet reached the
stapling position.
