[A]
[D]
Copies [A] exiting the copier pass t hro ug h the entra nce guide plates 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 proof tray)
When the S/S CPU receives the motor ON signal from the copier, the roller
drive motor [C] rotates all the rollers in the S/S paper path. At the same time,
the turn gate solenoid [D] is energ ized and the turn gat e turns clockwise. The
turn gate directs copies to the proo f tray [E] through the vert ical transport and
proof tray exit rollers [F,G].

The turn gate solen oid [A] stays off and th e turn gate [B] stays up when t he
S/S roller drive motor [C] starts rot at ing . The turn gate directs copies
downward and the bin transport belt [D] exits copies t o th e bin through the bin
transport and bin exit rollers [E, F].
The jogger bar [G] th en moves th e copy towards the front and jogs it ag ainst
the front side plate to sq uare the copies.
The bin lift motor [H] turn s on when this jogging operation is almost fin ished
and advances the bin one ste p up along the bin cam track [I]. The bin lif t
motor stops at the proper timing to position the next bin at the bin exit
section. This bin movement is done for each copy in the sort mode and for
the final copy of each original in th e stack mo de.
The up and down movement of th e bins in both the sort and stack modes is
the same as that for othe r mo ving bin type sorters.

When the final set of copies is jogged in the sort mode, th e staple unit staples
the stacked copies as follows:
(Figure 1)
If the final copy is exited to a bin other than the first one, all the bins lower to
the home position (the first bin is positioned at the bin exit sectio n). The
jogger bar [A] moves towards the front to jog the copies stacked in the first
bin. Then it stops 15mm away from the paper side edge.
(Figure 2)
The bins move one step up to place the first bin at the stap ling section.
(Figure 3)
The grippers [B] move forward, an d grip the copies.
(Figure 4)
The grippers bring the copies up unde rne at h the sta pler. At the same time,
the jogger bar jogs the cop ies stacked in the second bin as a prep aration for
the next stapling. Then the jog ge r bar ret urns to the position 15mm away
from the paper side edge.

The bins move one step up for the next stapling.
When the final set of copies is stapled, the bins lower and stop when the final
bin used just before the stapling operation is positioned at the bin exit section.
There are two staple modes.
1) Automatic stapling:
In ADF/ARDF mode, when the staple mode is selected before pressing
the start key, copies will be delivered to each bin an d sta ple d
automatically.
2) Manual stapling:
In sort mode, after copies are sort ed in the bins, the copie s will be stap led
when the staple key is pressed. In sta ck mode, manual stapling is
impossible.

The turn gate directs copies to the pro of tray or to the bins depe nding on the
mode.
In the normal mode, the turn gate solenoid [A] turns on tog et he r wit h th e
roller drive motor when the S/S CPU receives the motor ON signal from the
copier. The turn gate [B] rotates clockwise to direct copies upward [C]
through the vertical transport section to the proo f tray. The turn gate solenoid
stays on during the copy cycle s, and turns off when the proof tray exit sensor
detects the trailing ed ge of th e last copy an d the S/S CPU receives the motor
OFF signal from the copier.
In the sort, stack, or staple mode, the turn gate solenoid stays off to keep the
turn gate up so that copies are direct ed down ward [D] to the bin transport
section.
However, a certain number of pulse s (d epen din g on the pap er size) af te r t he
bin exit sensor detects the leading edge of the copy, the turn gate solenoid
turns on. When the trailin g ed ge of th e copy passes the turn gate (50 mse c.
after the S/S CPU rece ives th e pa pe r exit signal from the copier), th e tu rn
gate solenoid turns of f to direct the next copy downward. This turn gat e
movement is to correct the facecurl of the trailing part of the copy. This will
flatten the cop y, or give it a slight backcurl, and will help stack and jog copie s
in the bins smoothly.

The roller drive motor (stepper motor) [A ] drive s the proo f tra y exit rolle rs [B] ,
vertical transport rolle rs [C], bin tra nsport belts [D], bin transport rollers [E],
and bin exit rollers [F] via the front and rear roller drive belt s [G, H], pulle ys,
and gears, as shown above.
The roller drive motor turns on when the S/S CPU receives the motor ON
signal from the copier. When the proo f tray exit sensor [I] (in the normal
mode) or the bin exit sensor [J] (in th e sort /stack/staple mode) detects the
trailing edge of the final copy, the S/ S CPU inf orms th e cop ier th rou gh the
fiber cable and the interfa ce PCB . Then the copier sends the motor OFF
signal to the S/S to stop the roller drive moto r.
The S/S CPU monitors the roller drive motor speed by counting pulses of the
timing disc [K] through the roller drive timing sensor [L ].
12
Page 14
10 July 1992 ROLLER DRIVE AND CONTROL
The S/S CPU controls the moto r rota tio n at 2 speeds (no rmal an d hig h
speeds) to exit copies as fast as possible .
The normal speed depends on the copier’s p ape r tra nsp ort speed. The S/S’s
paper transport speed is almost the same but is slightly fast er th an the
copier’s.
In the normal mode, the roller drive motor changes the paper tra nsp ort speed
from normal to high (500 mm/sec., fixed) when the S/S CPU receives th e
paper exit signal from the copier. The roller drive mot or cha ng es the paper
transport speed from hig h to norma l 100 millisecon ds af te r t he proo f tra y exit
sensor detects the trailin g edge of the cop y.
In the sort/stack/sta ple mo de, the roller drive motor also changes the pap er
transport speed from normal to high and then fro m h igh to normal. The timin g
is the same as in the normal mode, bu t the bin exit sensor is used to dete ct
the trailing edge instead of the pro of tray exit sensor. The high speed is
almost double the normal speed, and it changes depending on the paper size
(900, 960 , or 1,000 mm/second).

bin lift motor [F] (dc motor) drives the bin lift wires through the bin lift drive
belt [G], bin lift gears [H], an d th e bin lift gear/pulley [I]. Then the bins are
driven up and down along the front an d rea r bin cam tra cks [ J].
The S/S CPU controls the amount of bin lift motor rotation by monitorin g the
pulses of the timing disc [K] th rou gh the bin lift timing senso rs 1 and 2 [L,M].
The bin lift timing sensor 1 is used for cou nting the timing pulses. The bin lift
timing sensor 2 is used to determine the mot or stop timing so that the edge of
the timing disc slots is not positioned at the timing sensor 1.

An end fence mylar [A] is stuck on each bin ent ran ce an d an end fence block
[B] is stuck on the mylar. These are stuck with two -side d ta pe, as shown in
figure 1. There is a twisted spring at the rea r end of the bin ent ran ce to raise
the end fence block and mylar. When the bin s are po sitio ne d at the bin home
position, the support bin [C] and th e first bin [D] are positio ne d at the bend of
the bin cam track [E] as shown. The supp ort and first bins have a space
between them so that the end fence mylar can fully rise until the end fence
block stops it.
The space between the support and first bin s is at the bin entra nce section
as shown in figure 2. Since the end fence mylar is t hin , a copy exits to the
first bin over the mylar. The steep angle of the bin helps th e exit ed copy slide
by its own weight under the mylar against th e bin ent ran ce.
While the bins move up alon g th e be nd of th e bin ca m track, the end fence
mylar and block of the first bin are lowered by the support bin. Those of the
second bin [F] rise as shown in figure 3.
When the bin lift motor stops, the first and second bins are positioned as
shown in figure 4. The copy in the first bin is prevented by the lowered end
fence mylar from moving out of th e jogged position. The end fe nce mylar and
block of the second bin are rea dy to receive the next copy.

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. Wh en a copy en ters t o
the sorter stapler entrance , th e jog ge r bar [A ] stays at the home position
which is detected by the jogger home position sensor [B].
At the appropriate timing for the selected pape r size, after the trailing edge of
the copy is detected by the bin exit senso r, the jogger motor [C] (stepper
motor) rotates and reverses to move the jogger bar via the upper and lower
jogger drive belts [D,E]. As the copy is exited into th e bin at th e center, the
jogger bar moves the copy all t he way to th e front, and pushes the pape r side
edge by 5 mm (0.2") an against the fron t side plate [F]. Then the jogger bar
moves back to the position which matches the paper width. Short ly aft er, the
jogger bar returns to its home posit ion . This jogger bar movement is
performed for each copy to square the copy stack in the exited bin.
In the automatic or manu al sta ple modes, the jogger bar also moves to
ensure squaring th e sta cked copies before stapling . How the jogger moves is
described in the Staple Mode sectio n of the Basic Operation instruct ions.

assembly are the gripper motor [D] (stepper mot or), dual cam p lat e [E], grip
home position sensor [F], grippers [G], and grip cam follower [H].
When the copier main switch is turned on, the grip motor ro tate s and/o r
reverses to position the whole gripper assemb ly at the home positio n. The
home position is detected by the grip home position sensor and the sensor
actuator on the dual cam plate.
(Figure 2)
When the bin lift motor stops during the automatic or ma nual sta plin g cycle,
the grip motor starts the rotation. As the dual cam plate turns counter clockwise, the cam groove [I] and th e pin [J] on the gripp er guide bracket

The sorter stapler main contro l board dete cts pape r jams in the sorte r stapler,
or between the sort er sta pler and the copier. The S/S CP U uses the paper
exit ON/OFF signal from the copie r, an d th e proof tray exit sensor [A] (in
normal mode) or the bin exit sensor [B](in sort/stack/staple mode) to detect
the jams.
The actual jam check timings in the no rmal and sort/stack/staple mode s are
shown above. There are two time scales: one in seconds and milliseconds,
and one in pulses. The pulses are the timing pulses from the roller drive
timing sensor. Since the paper t ran spo rt speed (normal speed) of the sorter
stapler depends on that of the copier, the sorte r st apler cannot operate on a
fixed time scale. Therefore , to match the sorter stapler speed to the copier’s,
the copier sends a signal to S/S CPU; this controls the normal speed of the
roller drive motor (high speed ne ver cha ng es) and this generates the pulse
rate.

10 July 1992 JAM DETECTION AND STAPLE ERROR
If the proof tray exit senso r o r the bin exit se nso r is act uated when the sorter
stapler unit or the front door is opened and closed, or when the main switch is
turned on, a sorter jam signal is sent to the copier.
Sorter jam conditions are rese t by op en ing and clo sing the sorter stapler unit
or the front door after clearing jammed paper.
When an abnormal condition of the main motor, bin lift mot or, or jogg er mot or
is detected for the first time, the copier’s operation panel will indicate a sorter
jam. When the abnormal condition is detected for the second time, the S/ S
CPU sends an error signal to the copier. The copier’s opera tio n panel will
indicate a service call code.
10.2 STAPLE ERROR
The sorter stapler main control board detects a staple error when the
following conditions are detected. The copier’s operation pan el will indica te a
sorter jam, and stapling op era tio n will st op in theses case s.
• If the paper sensor is actua ted when the sorter stapler or the front
door is opened or closed, or when the main switch is turned on.
• If the paper sensor is actua te d when the grip assembly retu rns to the
home position after the stapling operation .
• The first time an abnormal condition of the stapler motor or grip
motor is detected.
The second time an abnormal condition is detected, the copier’s
operation panel will indicate a service call code.
