MAIN BODY
Conveyance is accomplished by the drive force of the
M701 (paper conveyance motor), which is transmitted to
the conveyance rollers. The M701 is linked with the main
body, so that rotation is set to low or high speed according
to the conveyance movement during copying.
The M701 is controlled by the FS CB (FS control board).
Related signals are provided by the PS702 (paper
entrance detect PS), PS717 (conveyance cover open/
close detect PS) and the MS701 (front door switch) and
PS3 (paper exit PS) of the main body.

As paper passes by the PS3 of the main body, the
M701 conveys the paper at a low speed in relation
with the paper exit velocity of the main body. When
the end of the paper passes through the PS3, the
M701 then conveys the paper at high speed. The
M701 again changes to low speed after the specified
period of time when the end of the paper passes
through the PS702, ready to convey the next sheet of
paper.

MAIN BODY
The paper exit position of the FS is fixed, the selected tray
is elevated or lowered to the paper exit position. Control of
the tray up/down is by the M706 (tray up/down motor)
which drives wires which is connected to and moves the
trays up and down.
The M706 is controlled by the FS CB (FS control board).
Related signals are provided by the PS703 (paper exit
detect PS), PS706 (tray lower limit detect PS), PS716
(tray count PS) and the MS702 (shutter switch).

1. Operations
a. Tray lower limit detection operation
With the power swich turnd ON, and the PS706 OFF,
the M706 is reversed and the tray is lowered until the
PS706 is turned ON.
b. Tray count operation
One or two optional trays can be installed.
If PS716 goes OFF after the lower limit of the tray has
1
been detected, the machine judges that no optional
trays are installed.
When PS716 is ON, optional tray 1 is in place; in this
condition the M706 rotates normally, raising the tray
one step up until PS716’s detection position where
motion is stopped. Whether PS716 is ON or OFF at
this point determines whether optional tray 2 is in
place or not.
The number of trays is counted by means of a series
1
of operations.
After the tray count, the default tray that was set in
the key operator mode is set in the exit position.
c. Tray movement operation
If the exit tray has been selected at the LCD, then
1
when copying starts M706 turns ON and moves the
selected tray so that it sets into the exit position.
The number of times PS703 switches ON and OFF
sets the selected tray into the paper exit position.

d. Shutter switch operation
While the tray is in motion, the shutter, which
prevents the fingers or foreign objects from entering
the paper exit gate, is closed, with MS702 in the ON
position supplying 24VDC to the various loads. While
the tray is being raised or lowered the shutter is
opened and MS702 is OFF, interrupting the flow of
electricity and halting the motion of the FS.

(M707) and the roller being made to run forward.
(Does not apply to small paper sizes.)
In offset mode or staple mode, when the stacked
paper is conveyed, paper pressure being applied

The conveyed paper is sent to the stopper by the
friction of the conveyance belt and stacked.
*4 Stapler unit shift
The stapler unit is driven by the stapler shift motor;
1
the stapler unit is fixed on the staple base and
moved by a belt along a rail. Owing to the shape of
the rail, when the stapler unit is moved to either the
forward or rear positions, the unit rotates and it is
possible to staple slantwise.When the stapler is
set to staple in two locations, it moves to the first
location, puts in the first staple, then moves to the
second location to put in the second staple.

1. Operations
a. Normal alignment operation
The front and rear alignment plates work in symmetry
to the front and rear based on the center of the
alignment section, alternately aligning and releasing.
To create this symmetrical movement the M703 and
M704 always rotate in opposite directions.
Every five sheets of the conveyed paper are aligned
and sent on to the paper exit section.
The timing of the M703 and M704 are set to the
starting point by the ON/OFF of the PS702 (paper
entrance detect PS).
b. Offset (shift alignment) operation
1
The sheets corresponding to odd sets of copies are fed
to the paper exit unit as soon as they have been aligned
normally. (up to 5 sheets are stacked and exited.)
During the alignment operation for even sets of
copies, M703 and M704 rotate in the same direction,
shifting the sheets forward from the center. The
aligned sheets are then sent to the paper exist
unit.(up to 5 sheets are stacked and exited.)
1 OUTLINE
2 UNIT EXPLANATION
3 DIS./ASSEMBLY
During sorting and stapling, paper exited by the
conveyance section is sent to the alignment section by the
M702 (paper exit motor) reverse direction, then aligned by
the alignment plates driven by the M703 (alignment motor,
(rear)) and the M704 (alignment motor, (front)).
The home position of the alignment plates is detected by
the PS709 (alignment plate detect PS (rear)) and the
PS710 (alignment plate detect PS (front)). The FS CB (FS
control board) controls the M702, M703 and M704. The
related signal are passed to the PS702 (paper entrance
detect PS).
c. Staple mode operation
In the staple mode, the M703 and M704 are released
after the stapling action is completed.
The ON/OFF timing of the M703 and M704 is set as
the M702 is turned from OFF to ON, and the PS702 is
turned OFF after the specified period of time.

A mechanical clutch is connected to M702 (paper exit
motor). A mechanical clutch can convey the forward
direction driving power to the exit roller with certain
movement.
The M702 is responsible for speed control for connection
with the mechanical clutch, for sending the alignment
section at the reversal rotation, and also during the usual
paper exit.
The M702 is controlled by the FS CB (FS control board).
The related signals are M707 (paper pressure motor),
M708 (stapler motor), PS701 (paper pressure PS), PS702
(paper entrance detect PS), PS703 (paper exit detect PS),
and PS707 (no paper detect PS).

1. Operation
During paper exit, both upper and lower exit rollers
are compressed as a consequence of the operation
performed by M707, and that condition is detected by
the ON/OFF state of PS701.
a. Non-staple mode operation
The ON/OFF timing of M702 is such that it turns ON
during the OFF of PS3, and turns OFF during the
OFF of PS702.
After the paper exit tray goes up until PS703 turns
ON, M706 moves the tray up and down in order to
keep the ON state of PS703 during paper exit.
b. Staple mode operation
M702 turns ON a certain time after M708 finishes the
stapling operation and turns OFF.
The subsequent operations are the same as for the
non-staple operation.

a. Stapler operation
After the aligning operation of the last paper, M707 is
turned ON and compresses the paper using the exit
rollers. Then, M708 is turned ON and stapling begins.
When PS701 is turned OFF, M707 is turned OFF,
PS712 is turned ON, and M708 is turned OFF.
For continuous stapling, M705 is not turned ON, and
the stapler unit waits for the next stapling at the same
position.
In the case of 2 stapling positions, the first staple is

executed and then M705 moves the stapler to the
specified position for the second staple. M708 then
turns ON and executes the second staple. At this
moment, if continuous stapling has been selected,
the stapler unit stops at the immediately previous
stapling position. When the first stapling operation of
the next paper is done, M705 moves the stapler unit
for the second stapling operation.
After the copy is finished, the stapler unit returns to its
home position.
