1.5 BASIC OPERATI ON
[B]
[A]
[F]
[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.

[A]
Depending on the sele cte d finishing mode, the copie s are directed up or
down by the junction gate [A], is controlled by a solenoid.
(1) When the exit sensor of the copie r is activat ed while in staple mode, the
solenoid [B] is energ ized . Then, the junction gate dire cts the copies down
to transport them to the jogger unit.
(2) When the exit sensor of the copie r is activat ed while in the sort/stack
mode, the solenoid sta ys o ff . The ju nct ion gate directs the copies up to
deliver them to the shift tra y.

[I]
[E]
[F]
[A]
[J]
[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.
