8/19/1999 4 – 1

A. Upper paper transport section
1) Paper transport
By rotating the main driving motor (FM), the transport rollers in the
finisher are driven.
2) Paper discharge gate 1 (1)
The paper discharge gate 1 (1) is operated by the paper discharge
gate 1 solenoid (OG1SL), to select between the routes for paper
discharge to the tray 1 (8) and transport to the tray 2 (5)/staple tray.
3) Paper discharge gate 2 (6)
The paper discharge gate 2 (6) is operated by the paper discharge
gate 2 solenoid (OG2SL) to select between the routes for paper
discharge to the tray 2 (5) and transport to the staple tray.
4) Trays 1 (8) and 2 (5) paper discharge operation
When paper is discharged to tray 1 (8) and tray 2 (5), tray 12 reduc-
tion clutch (11) is operated at the paper discharging timing to reduce
the speed of paper discharge rollers 1 and 2, improving the accuracy
of paper alignment in tray 1 (8) and tray 2 (5).
5) Trays 1 (10) and 2 (7) paper full detection
Whether the trays 1 (10) and 2 (7) are filled with paper is detected by
the tray 1 and 2 paper full sensor.

B. Staple tray
1) Jogger motor (JGM)
The jogger motor is driven when the paper is fed into the staple tray,
to operate the jog plates F and R so as to align the sideways edge of
the paper.
2) Paddler (11)
The paddler clutch (PDCL) is turned ON when the paper is fed into
the staple tray, to give the paddler a full turn so as to drop the paper
downward (pusher), thus achieving alignment in the vertical direction.
3) Pusher motor (PSM)
With the pusher motor rotating, the paper stored inside the staple tray
is lowered from the home position (discharge position) to the stapling
position; after stapling, the paper inside the staple tray is elevated
from the stapling position to the home position.
4) Staple unit movement motor (STUM)
The staple unit is moved to the stapling positions (front, far end, 2
centers) by the staple unit motor.
5) Staple tray paper discharge
When the paper delivery roller pressure release clutch (STORCL) is
turned ON, the paper delivery pressure release roller (4) is pres-
surized through the cam to discharge the paper from the stable tray.
6) Paper discharge gate 3 (5)
The paper discharge gate 3 (5) is operated by the paper discharge
gate 3 solenoid (OG3SL) to switch over the routes of paper inside the
staple tray between the paper discharge side and the staple side of
the off-set tray.
7) Tray 3 paper discharge motor
The tray paper discharge motor (12) is rotated to drive the paper
discharge rollers 3 and 4 to discharge paper to the tray 3.

(Operation of stapling)
Jogging in lateral direction
1) The jog plates are moved to the stand-by position before the
paper is fed to the staple tray.
2) Immediately after the paper is fed into the staple tray, the jog plate
is moved to the paper size position to ensure the alignment of the
paper.
Staple unit movement at the time of stapling (1-point
stapling)
1) The stapler unit is moved to the stapling position.
– The number of sheets to be stapled is fed to the staple tray –
2) The pusher (the sheets to be stapled) is lowered to the stapling
position.
3) The paper is stapled ... (in the case of 2-point stapling, the action
that is described on the following page is added.)
4) The pusher (the sheets stapled) is elevated to the paper discharge
position.
5) After the job, the stapler unit is returned to the home position.
Stapler unit movement at the time of stapling
(2-point stapling action is added.)
1) The pusher is elevated to the position which makes it possible for
the staple unit to move.
2) The staple unit is moved to the staple position where the 2nd
staple is driven.
3) The pusher (sheets to be stapled) is lowered to the stapling posi-
tion.
4) Sheets are stapled.
5) The staple unit is returned to the 1st staple position.
(After the job is finished, the staple unit is returned to the home
position.)
D. Off-set tray
1) Off-set motor (3)
When the off-set motor (3) is driven, the tray is shifted sideways
against the direction in which the sheets are delivered, so that the
sheets discharged into the off-set tray (1) are sorted by the specified
number of sheets. The rotation is unidirectional and controlled by the
crank. The motor is stopped by the off-set home position sensor (2)
turning ON.
No. Signal name Part name

(2) OFHP OFHP Off-set home position sensor
(3) OFM Off-set motor
E. Elevator
1) Elevator motor (3)
When the elevator motor (3) is driven, the winding pulley (5) is rotated
in both forward and reverse to wind up the wire (6) stretching vertical-
ly so that the tray 3 (off-set tray) is moved up and down. This allows
the discharge of paper at a fixed position according to the number of
sheets to be loaded on the off-set tray.
2) Off-set tray full and load detection
When the power is turned ON, the off-set tray lowers to the lower limit
sensor (4) position. Then it elevates until the upper limit sensor (7)
turns ON, while counting the encoder pulses of the elevator motor (3).
The volume of paper loaded on the off-set tray is calculated (0 -
100%) by counting the number of pulses from the elevator encoder
(1).
The off-set tray is judged to be full when both the lower and upper
limit sensors (4), (7) are turned ON.
