Mechanism
Tray full detection mechanism
When the paper exit full sensor 1 [A] or the paper exit full sensor 2 (staple) [B] detects paper, the paper
exit tray is full. Paper feed is stopped temporarily while the tray is full, and is restarted after the paper is
removed.
The paper exit full sensor 1 is at the center of the main scan (side-to-side), and detects the total
quantity of paper in the paper exit tray.
If the paper is stapled, the height of the paper around the stapled area is higher than that of the other
areas. The paper exit full sensor 2 (staple) is located at the stapling area, and detects the quantity of
stapled paper.

Straight paper exit/shift paper exit mechanism
Paper from the main machine is transported to the paper exit roller [B] and paper exit belt [A] via the
shift rollers ([C] and [D]). The transport motor drives the shift rollers, reverse rollers and paper exit
rollers.
After passing through the paper exit roller of the main machine, to shift the paper from side to side, the
shift rollers ([C] and [D]) nip the sheets and the shift motor moves the paper towards the front or rear of
the machine.

1.Detailed Descriptions
10
If the paper is still held by the paper exit rollers, this will stop the paper from shifting, so the paper exit
rollers ([A] and [B]) are moved from their home (strong pressure) positions to their pressure release
positions.
Shift mechanism
Shift roller operation timing
Paper is shifted when the distance between the trailing edge and the paper exit roller on the main
machine is 10mm (the entrance sensor detects the leading edge of the paper).
The shift motor [A] rotates clockwise/anti-clockwise to shift the paper towards the front/rear of the
machine.
The shift amount is 20mm when shifting towards the front, and 10mm when shifting towards the back.
The home position is located at the back end of the shift area, and is detected by the shift HP sensor
[B].

Paper exit roller/paper exit belt release mechanism
Pressure release timing of the paper exit rollers
•Waiting (before paper is received): Strong pressure
•When paper is transported: Pressure released
•When paper shift is completed (shift motor stops): Strong pressure
When paper is transported, the paper exit rollers/paper exit belt ([A] and [D]) are at the pressure release
position so that they do not interfere with paper shifting.
When paper shift is completed, the rollers are moved to the strong pressure position for paper
transportation and paper exit.
Positions of the paper exit roller/paper exit belt
•HP (strong pressure)
•Pressure release position
•Weak pressure position
The paper exit pressure motor [B] rotates clockwise/anti-clockwise to drive the paper exit drive belt [D]
to the strong pressure or weak pressure positions.
The paper exit pressure HP sensor [C] detects the home position.
Details of each position
•Home position (strong pressure position)
This is used for paper transportation and paper exit. The pressure increased using the paper exit
pressure motor [B], and the paper exit roller (drive) [A] and the paper exit belt (driven) [D] come
into contact in order to nip the paper firmly.
[C] is the paper exit pressure HP sensor.

1.Detailed Descriptions
12
•Pressure release position
The nip of the paper exit roller/paper exit belt is released so that they do not interfere with paper
shift.
•Weak pressure position
This is used during stapling, when there is already paper stacked in the paper exit tray, and more
paper is being transported.
The paper exit pressure motor [B] lowers the pressure, and the position of the paper exit belt
(driven) is moved so that the middle part of the belt comes in contact with the paper exit roller
(drive).
The weak pressure position is for preventing smudges or stains caused by paper rubbing against
the paper that is already stacked.

Staple eject mechanism
•Transport/adjustment of paper position (home position)
This finisher does not have a jogger. Paper position (side-to-side) is aligned using sensors, by
registration adjustment during paper transportation.
The leading edge of the paper transported from the main machine is detected by the entrance
sensor [D]. After the trailing edge has passed through the paper exit rollers of the main machine,
the paper is transported by the shift rollers ([A] and [B]) for shifting. The paper is shifted to the
position where the sub-scan registration sensor [C] detects the rear edge of the paper (as viewed

1.Detailed Descriptions
14
from the front of the machine). During paper shifting, the paper exit roller and paper exit belt move
to the pressure release position.
•Stacking (Position B)
After shifting is completed, the paper exit rollers move to the strong pressure position and received
the paper from the shift rollers. After the trailing edge of the paper has passed the junction gate, the
paper exit roller rotates in the opposite direction. Paper is transported to the stacking area, and
then passed through the reverse rollers [H].
At this time, the junction gate [J] moves to the lower position (the gate’s edge is raised, as shown
by the blue arrow and circle) to bring paper to the stacking area.
After paper is transported to the reverse rollers, the paper exit rollers move to the pressure release
position to allow shifting of the next sheets (as shown by the red arrow). When the transported
sheet of paper touches the stack guide [K], the paper is aligned (main-scan direction). After the
paper is stacked, the trailing edge presser [I] moves to the press position (the reverse rollers move
to the pressure release position) and holds back the stacked paper.
