The grip plate and alignment plates on the
conveyance drum do not use electrical control, they
operate only through the rotation of the drum. (The
grip plate is driven by the drum via a cam
arrangement, and the alignment plates are driven by
the centrifugal force and their own weight.)
The conveyance drum and conveyance rollers are
controlled electrically by conveyance drum motor
(M807) and conveyance motor (M801).
*3: Tray lift
The paper exit position for the paper sent to tray 2/3
is fixed. Switching between tray 2 and tray 3 is carried
out by changing the tray position with the tray lift (up/
down) mechanism.
The tray lift mechanism is driven by the tray up/down
motor (M804) whose driving force is transmitted to the
tray by a wire arrangement.

2 UNIT EXPLANATION
3 DIS./ASSEMBLY
Paper exit conveyance takes place as a result of the
transmission of the drive force of motor M801
(conveyance) to the paper exit rollers and conveyance
rollers. The paper conveyance path is switched between
tray 1 or tray 2/3 by solenoid SD801 (gate).
M801 and SD801 are controlled by the FNSCB (FNS
control board).
1. Operation
a. Gate switching operation
Normally, SD801 is OFF and the gate allows paper to
exite to tray 2/3. When tray 1 is selected as the paper
exit tray, SD801 goes ON, the gate is switched, and
the paper is conveyed to tray 1.
b. Conveyance operation
M801 is turned ON and OFF in conjunction with the
copy operation of the main body. During operation of
the main body, the M801 rotates constantly, enabling
paper conveyance at any time.
When paper has been conveyed to tray 2/3, the
status of the PS802 (drum entrance) and main body
PS1 (paper exit) causes the M801 to be switched
from low speed to high speed. The high-speed
activation signal and the rotation speed depend on
the paper size.

The paper that has been sent to tray 2/3 is exited into the
respective tray by the conveyance drum. The conveyance
drum is driven by M807 (conveyance drum) which is
controlled by the FNSCB (FNS control board).
1. Operation
a. Conveyance operation
When PS802 (drum entrance) detects the leading
edge of the paper and goes ON, M807 is turned ON
after the specified time, and the conveyance drum
starts to rotate.
To convey one sheet of paper, the M807 is switched
through a predetermined sequence of three speeds.
When the conveyance drum reaches the standby
position, the motor is switched OFF.
During this time, the drum makes one revolution
which includes gripping, conveying, and releasing the
paper.
b. M807 speed control
When the conveyance drum rotation pulses reach a
predetermined number, the rotation speed is
changed.

The paper exit position of the conveyance drum is always
fixed, and tray switching is carried out by raising or
lowering tray 2/3.
The up/down motion is achieved by transmitting the
driving force of motor M804 (tray up/down) to the lift wires
connected to each tray. This operation is controlled by the
FNSCB (FNS control board).
M804
PS805
PS806
1. Operation
Normally, the paper exit position of the conveyance
drum is aligned with tray 2. Therefore no lift operation
is carried out when tray 2 is selected.
a. Upward movement
When tray 3 is selected as paper exit tray and PS806
(tray lower limit) is ON, M804 (tray up/down) goes ON
(forward rotation). Tray 2 and tray 3 are then raised
simultaneously.
When the upward movement causes tray 2 to switch
PS805 (tray upper limit) to ON, M804 goes OFF and
the upward movement stops. Tray 3 is now aligned
with the paper exit position of the conveyance drum.
b. Downward movement
When tray 2 is selected as paper exit tray and PS805
is ON, M804 goes ON (reverse rotation). Tray 2 and
tray 3 are then lowered simultaneously.
When the downward movement causes tray 3 to
switch PS806 to ON, M804 goes OFF and the
upward movement stops. Tray 2 is now aligned with
the paper exit position of the conveyance drum.
c. Tray squeeze prevention
During tray upward or downward movement, if a
foreign object is caught between the tray and the
finisher unit, MS802 (up/down (upper)) or MS803 (up/
down (lower)) will mechanically go OFF, causing the
power supply line of M804 to be cut off.

*2: Paper exit
The paper being supplied by the conveyance drum is
conveyed to the stapling position, regardless of
whether stapling will be carried out or not. If stapling
is enabled, the stapled stack is exited to tray 2 or 3
after stapling. If stapling is not enabled, each sheet is
exited individually to tray 2 or 3.
This movement is performed by the exit levers which
are driven by the paper exit motor (M805).

*4: Staple accident prevention
A shutter cover is provided to prevent the user from
inadvertently inserting a finger etc. into the stapler. The
shutter cover is driven by the shutter SD (SD802) which
is ON during stapler operation and during stapler unit
movement. The shutter cover blocks the clearance
between the paper exit tray and the stapler unit.
*3: Paper stacking
A spring arrangement in the bottom of tray 2 and tray
3 lifts the bottom plate up, so that it always is in direct
contact or not more than 3 mm away from the paper
exit roller assembly.
[ Operation in through mode ]
The paper is stacked on the tray by the movement of
the exit lever and the rotation of the paper exit roller
(A) of each tray.
When the paper exit roller (A) turns, the tip of the
paper is grasped by the rollers and is stacked under
the rollers.
[ Operation in offset mode ]
The paper is offset by the alignment plates (front/
rear), and is stacked on the tray by the movement of
the exit lever and the rotation of the paper exit roller
(A) of each tray.
By repeating this action, the tip of the paper is
grasped by the rollers and is stacked under the
rollers.

b. Shift alignment operation
During the first alignment operation, the alignment
plate (front) and alignment plate (rear) are front and
rear symmetric with respect to operation as reference
with the center of the tray and paper is exited.
During the next alignment operation, the alignment
plate (front) and alignment plate (rear) are not front
and rear symmetric with respect to operation as
reference with the center of the tray and paper is
exited at the position shift to the first copy.
From now on, these operation are repeated.
The ON/OFF timing of M809 and M808 is the same
as that of the non-shift alignment operation.
c. Staple mode operation
In staple mode, M809 and M808 perform release
operation after stapling is completed. The ON/OFF
timing is based on the OFF timing of the stapler motor
that last completed a stapling operation (M802 or M803).

The paper exited by the conveyance drum is aligned on
the center of the respective exit tray by the alignment
plates driven by the M808 (alignment (rear)) and M809
(alignment (front)). M808 and M809 are controlled by the
FNSCB (FNS control board).
1. Operation
a. Non-shift alignment operation
The alignment plate (front) and alignment plate (rear)
work symmetrically, with the tray center serving as
the reference point. The guides repeat the alignment
and release pattern. The rotation direction of M809
and M808 is therefore always opposite.
The ON timing of M809 and M808 is referenced to the
ON/OFF state of PS802 (drum entrance) or PS804
(paper through detect). Which sensor is used
depends on the paper size.

1. Operation
a. Non-stapling mode operation
The drive gear for the exit levers is controlled using
the home position detected by PS813 (paper exit
motor HP).
When PS804 (paper through) detects the paper
leading edge and goes ON, M805 goes ON for the
specified time and drives the exit levers. This causes
PS813 to go OFF.
The exit levers are connected to the circumference of
the drive gear. Within one rotation of the gear, the
paper is pushed out (forwarding motion) and returned
to the standby position (return motion).
When PS813 goes ON, the exit levers have returned

b. Tray auto-switching control
When copying is carried out with tray 2 or tray 3
specified as output tray and the specified tray
becomes full, causing PS807 or PS809 to become
ON, the output tray is automatically switched to the
other tray.
This operation is also valid if tray 1 is specified as the
output tray. The output tray will be switched to tray 2
or tray 3. Normally, tray 2 will be selected. If it is full,
tray 3 will be selected. Switching from tray 2 or tray 3
to tray 1 is not possible.

The paper exited to tray 2 or tray 3 is placed on top of the
paper exit rollers of the respective tray. The drive force of
motor M810 (tray 2) or M811 (tray 3) is used to operate the
rollers and stack the paper on the tray.
M810 and M811 operation is controlled by the FNSCB
(FNS control board).
1. Operation
a. Paper stacking control
When M805 (paper exit) goes ON, M810 (tray 2) or
M811 (tray 3) are set to ON after the specified time.
When M805 goes OFF, M810 or M811 are set to OFF
after the specified time. While the motor is ON, the
rollers of the tray are driven and the paper that was
placed on the rollers is stacked.
The stacking section of the tray is pushed up by a
spring. When the maximum allowable number of sheets
has been stacked, the stacking section contacts the
bottom of the tray and PS807 (tray 2 full-stack detect) or
PS809 (tray 3 full-stack detect) goes ON.
When PS807 or PS809 are ON, no copy operation
will be carried out when the respective tray is
selected.

The position of the stapler units at the front and rear with
respect to the paper is adjusted using the driving force of
the M806(stapler movement). Operation of M806 is
controlled by the FNSCB (FNS control board).
1. Operation
Normally, the stapler units are stationary, positioned so
that the stapling is carried out parallel to the paper edge.
This position is detected by PS814 (stapler unit HP).
When the stapling position is changed according to a
command from the main body, M806 goes ON and
the two stapler units at the front and rear are moved
simultaneously. The M806 OFF timing is controlled
using the number of drive step from when PS814
went OFF.

1. Operation
a. Stapling operation
M803 (stapler (front)) goes ON when the last paper
alignment operation is completed, and goes OFF
when PS817 (stapler HP (front)) goes ON.
This causes the front side of the paper to be stapled.
When stapling at two locations is carried out, M802
(stapler (rear)) goes ON after the specified time,
measured from the point when M803 goes ON. It
goes OFF when PS820 (stapler HP (rear)) goes ON.
b. Shutter control
During stapler unit movement and during stapling
operation, the SD802 (shutter) is ON, causing the
shutter to block the clearance between the paper exit
tray and the stapler unit.
c. No-staple detection
The front and rear stapler units are each equipped
with a PS818, PS821 (no stapler (front), (rear)).
When staples have run out and the no staple
condition is detected, a message is shown on the
display of the main body.
