Full detection
Paper full on the tray 2 is detected in combination between the
lower limit sensor ON and detection of the top of paper bundle on
the tray by the paper exit actuator.

(4) Offset tray section
·
Offset motor
The offset motor moves the offset tray vertically to the paper exit
direction so that each bundle of paper discharged to the offset tray
is separately grouped.

is separately grouped.
·
Paper exit clutch
This clutch is turned on when a stapled bundle of paper is dis-
charged so that the bundle of paper is warped by the difference
between the speeds of the upper and the lower paper exit rollers,
preventing the bundle from being caught by the preceding bundle’s
staple.

b. Alignment unit section
(1) Transport switch gate right (gate right solenoid)
Selection between the transport section and the alignment section
in the alignment unit is made by the transport switch gate right.
This gate drops the rear edge of paper entering the alignment
section so that the rear edge is completely transported.

(2) Rear edge plate unit
·
Rear edge plate motor
The motor is turned on at the timing when paper enters the align-
ment tray to drive the rear edge plate unit. Paper of A3 or WLT is
aligned to the shutter, and paper of a smaller size is aligned to the
right side of the alignment tray in the transport direction.
ment tray to drive the rear edge plate unit. Paper of A3 or WLT is
aligned to the shutter, and paper of a smaller size is aligned to the
right side of the alignment tray in the transport direction.
·
Rear edge plate solenoid
After provisional alignment of small size paper, this solenoid puts
down the rear edge plate of the rear edge unit to pass it under the
aligned paper. After returning to the home position, it is turned off
and the rear edge plate is put back and paper is transported to the
shutter.

aligned paper. After returning to the home position, it is turned off
and the rear edge plate is put back and paper is transported to the
shutter.
(3) Side guide plate (Guide plate motor)
When paper enters the alignment tray, this plate is driven to align
paper vertically to the paper transport direction toward the fixed
wall of the alignment tray front side.

wall of the alignment tray front side.
(4) Shutter (Shutter solenoid)
The shutter solenoid drives the shutter which stops the lead edge
of paper for alignment. After stapling, the shutter is put down to
transport paper to the paper exit roller.
of paper for alignment. After stapling, the shutter is put down to
transport paper to the paper exit roller.
(5) Transport switch gate left (Gate left solenoid)
Paper passed through the escape transport path is sent to the tray
1 or to the tray 2.

4. Basic operations
A. Flowchart of basic operations
The initialization (home positioning of each motor) is performed at the
following timing:
following timing:
1) When the power is turned on.
2) When the staple section door on the upper side of the finisher
paper exit unit is opened or closed.
3) When the alignment unit is opened or closed.
4) When the copy start key is pressed (JOB_START): Recovery op-
eration
5) When copying is completed (JOB_END).
6) When a jam occurs: Jogger saving
