B. Reversion unit
1) Reversion motor (RVM)
The reversion motor is connected to the reversion roller (4).
The paper is pulled into the reversion path by the reversion motor
rotating in forward, and fed into the upper transfer route by the motor
rotating in reverse. When the paper is discharged through the short-
path, its transfer is performed by the reversion roller (4) until the
paper enters the staple tray.

rotating in reverse. When the paper is discharged through the short-
path, its transfer is performed by the reversion roller (4) until the
paper enters the staple tray.
2) Reversion pressure release roller
The reversion pressure release roller (3) is pressure released or pres-
surized through ON/OFF control of the reversion roller pressure re-
lease solenoid, to achieve the reversion of the paper at a high speed
without reducing JOB efficiency.

C. 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 sidewise edge of
the paper.
to operate the jog plates F and R so as to align the sidewise edge of
the paper.
2) Puddler (11)
The puddler clutch (PDCL) is turned ON when the paper is fed into
the staple tray, to give the puddler 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) Short path switching gate (1)
The short path switching gate (1) is operated by the short path
switching solenoid (SPSL), to select the short path to feed paper to
the reversion path and stable tray.

6) Staple tray paper discharge
When the paper delivery roller pressure release clutch (STORCL) is
turned ON, the paper delivery pressure release roller (4) is pressur-
ized through the cam to discharge the paper from the stable tray.

7) 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.

8) Tray 3 speed change clutch (8) (2)
The paper discharge rollers 3 and 4 are speed changed to improve
the stackability of stapled paper being discharged to the off-set tray.
