[D]
[C]
[E]
After the copy is complet ed , the paper is directed to the finisher. If the
sort/stack mode is selecte d, the junction gate [A] directs the paper upwards
to transport it to the shif t tra y [B] . In the se mod es, the shift tray is shifted from
side to side to stagger a nd sepa rat e set s of copies. The amount of shift is
approximately 30 mm.
When the staple mode is selected, the junctio n gate direct s the paper below
to transport the paper to the jo gger un it [C] . Ea ch time a copy is delivered to
the jogger unit, the position ing ro ller [D] , th e alignment brush roller [E], and
the jogger fences [F] square the stack of copies. Af ter the final copy of the set
is squared, the set is stapled, and then delivered to th e shift tray.

[C]
[G]
The vertical position of the shift tray [A] is controlle d by the shif t tra y lif t mot or
(dc motor) [B] through gears and timing belts [C]. Whe n the main switch is
turned on, the tray position is initialized to the upper posit ion . The tray’s
uppermost position is detected when the shift tray pushes up the actuator [D]
to deactuate the stack he ight sensor 1 [E].
While copying, the actua to r [ D] is grad ua lly raised as the copy stack grows. In
the sort/stack mode, when stack height sensor 2 [F ] rema ins actuated for 4
seconds, the shift tray lift moto r [B] rota te s, lowering the tray unit for 50 ms.
In staple mode, when the stack height sensor 1 re main s dea ctuated for 4
seconds, the motor rotate s, lowering the tray until the sensor [E] is actu at ed .
When the tray reaches its lower limit position, the lower limit sen sor [G] is
actuated by the actuator [H], and copy operation stops.
After the copy proce ss is finished and the machine stop s, th e tray is raised to
its upper most position 4 seconds after the copies are removed.
A mechanical safety switch [I] is inst alle d to preve nt the drive gears from
being damaged if the sensor doe s not work. Whe n th e shift tray pushes up
the shift tray positioning roller [J], the shift tray lift motor stops.

[H]
In the sort/stack mode, the shift tray [A] moves from side to side to stagger
and separate sets of copies.
The horizontal position of th e shif t tray is controlled by the shift motor (d c
motor) [B] and the shift cam (helical cam) [C]. After one set of originals is
copied and delivered to the shift tray, the shift moto r [B] start s rota tin g, driving
the shift cam through the timing belt. The pin [D] fixed to the shift tray base
plate [E] is position ed in the groo ve on the shift cam, creating the side-to -side
movement required to sta gger copies.
When the shift cam rotates 180 degrees (when the tray is fully shifted.), the
plate [F] on the shift cam pushes the actu at or [G] of the shift tray half-turn
sensor [H] and the shift motor sto ps. The next set of copies is then delivered.
The motor rotates rep ea tin g the same process and moving the tray ba ck to
the previous position.

In the staple mode, copies are vertica lly a nd horizo nt ally alig ne d in the jog ge r

For horizontal paper alignment, the jogger mot or [A ] moves both the front and
the rear jogger fences [B ] to align the copies.
For vertical paper alignment, the positio nin g rolle r [C] and the alig nme nt
brush roller [D] push the copy again st th e stack stopper [E].
After the trailing edge of the copy pa sses th e jogge r unit entrance sensor [F],
the positioning roller sole noid [G] is energized for 280 ms pushing th e
positioning roller into con ta ct with the paper. The po sitio nin g rolle r ro tate s to
push the paper back and align the trailin g edge of the pape r against the stack

When the Start key is pressed, the copier sends the paper size information to
the finisher. In accordance wit h th at data, the jogger motor (stepper mot or)
starts rotating to position the front and rear jogg er fe nces [A] 7 mm away from
the selected paper’s edges. (1)
After the trailing edge of the copy pa sses th e jogge r unit entrance sensor,
each jogger fence moves inwa rd 5 mm. The y st op 3 mm away from the paper
edges. (2)
Just after the positioning ro ller pushes the copy back, each jogger fence
moves inward 2 mm more so that the leaf spring [B] on the rear jogg er fe nce
pushes the copy side edge slightly.
After a copy is stacked in the jogg er tray, the jogger fences move back 7 m m

After being stapled, the stack feed-out motor [A] starts rotating. The pawl [B]
on the lift belt [C] transports the set of st apled copies up, and feeds it to the
shift tray. Approximate ly 0.6 secon d after the stack feed-out mot or sta rts, the
motor stops for 400 ms. At this moment , th e exit ro llers cat ch th e sta ple d
copies to feed them out to th e shift tray. Then the motor rot ates again until
the pawl actuates its home position sensor [D].
The exit drive motor starts rotating to drive the exit rolle rs [E] when the first
copy activates the entrance sensor. The exit drive motor speed is reduced
just before each copy paper is comple tely fed out. This is to ensure an even
copy stack.

NOTE: In the stapling copy mode (unlike the sort copy mod e), the machine
cannot detect if the copy st ack on the tray is remove d. This is
because the stack heig ht sensor 1 [A] is always ON while in this
copy mode. To counter th is, whe n the shift tray rise mode is selecte d
by turning on DIP switch 101-1 on the finisher main control board ,
the shift tray slightly mo ves up just when the stapled copy is
delivered. At this time, if the stack he igh t sensor 1 turns off, this
means that the tray is in the proper po sitio n. The tra y mo ves down
soon and returns to the original position (unt il the sensor turns on
again). If the sensor remain s ON, th is mean s tha t th e tra y position is
too low. The tray continu ously mo ves up unt il the senso r turns off
then moves down until the sen sor tu rns on . In this mode the shift tray
motor frequently raises or lowers the shift tra y to monitor the paper
height.
To reduce the load to the shift tray motor, this mode is not enabled
