• Inverter
Distributes paper to the proof tray, the shift mode, or the staple mode. The destination varies depending on
whether the paper is sorted or stapled, or not.
• Pre Stack Tray
When stapling two or more sheets, the 1st to 3rd sheets wait in the pre stack tray and are then transferred
together to the stapler. The following sheets (4th, 5th…) are sent to the staple tray two by two. This method
contributes to reducing waiting time to enhance productivity for stapling.
Supported Sizes: A4 SEF, B5 SEF, LT SEF

Mechanism Details
Inverter
The inverter mechanism has two junction gates that can send paper in one of three ways. For proof tray output, a
motor moves the proof junction gate into position to send paper to the proof tray. In staple mode, another motor
moves the stapler junction gate into position to send paper to the stapler. In shift mode, paper is sent to the shift
tray, and neither junction gate changes over.

Shift Tray

1 Shift Tray End Fence 3 HP Sensor
2 Shift Gear Disk 4 Shift Tray Half-turn Sensors
• Shift T ray
In shift mode, when the last printed paper has been output, the shift motor moves the shift tray to the left or
the right. When one of the half-turn sensors detects one of the slots in the shift gear disk, the motor stops.
The shift amount is 15mm..
• Up / Down
The shift tray moves up or down depending on the stack height of the output paper. The degree of motion is
adjusted to keep the paper height sensor actuator (3) between the two paper height sensors (1, 2).

1 Paper Height Sensor – Standby Mode 4 Shift Tray Full Sensor (Large Paper)
2 Paper Height Sensor – Staple Mode 5 Shift Tray Full Sensor
3 Paper Height Sensor Actuator 6 Paper Height Sensor – Shift Mode
• Shift Up
When paper is removed from the shift tray, the feeler moves down and the paper height sensor (staple mode)
turns ON. Then the shift tray lifts until the sensor turns “OFF”.
• Shift Down (Shift Mode)
With stacked paper on the tray, the paper height sensor (standby mode) is turned “OFF”. Then the shift tray
lift motor turns “ON” to lift the tray until the sensor turns “ON”.
• Shift Down (Staple Mode)
When a stapled stack of paper has been output, the shift tray lift motor turns ON for a certain time to move
the tray down a set distance. Then the motor lifts the tray until the paper height sensor (staple mode) turns
from “ON” to “OFF”. The tray is now at the home position. This is done every time after a stapled stack of
paper is output. There are three shift tray full sensors, but only two of these (4, 5 in the above diagram) are
used for the machine display.
Rough Indication:
Larger Size (B4 or larger): 1,500 sheets
Smaller Size (less than B4): 3000 sheets
• Drag Roller Operation
The drag roller mechanism improves the accuracy of paper stacking on the tray by pushing the output paper

back against the end fence. The drag roller motor drives the roller.
Pre-stack
The First Three Sheets
1. The rear edge of the 1st sheet passes the entrance sensor. Then the left and right pre-stack inverter plates shift
to the left. This closes the 2nd and 3rd paths to send paper to the 1st path.
2. The rear edge of the 2nd sheet passes the entrance sensor. Then the pre-stack inverter plate (right) shifts to
the right. This opens the 2nd path to send the 2nd sheet to the 2nd path.
3. The rear edge of the 3rd sheet passes the entrance sensor. Then, the pre-stack inverter plate (left) shifts to the
right. This opens the 3rd path to send 3rd sheet to the 3rd path. Then, after the leading edge of the 3rd sheet
passes the pre-stack sensor, the three sheets of paper (1st, 2nd, 3rd) are sent to the stapler tray at the same
time.

Pre-stacking for Subsequent Sheets
When the rear edge of the 4th sheet passes the entrance sensor, the pre-stack inverter plate (left) shifts to the left to
open the 2nd path. This sends the 4th sheet to the 2nd path.
Then, after the leading edge of the 5th sheet passes the entrance sensor, the pre-stack inverter plate (left) shifts to
the right to open the 3rd path. This sends the 5th sheet to the 3rd path. When the leading edge of the 5th sheet
passes the pre-stack sensor, both sheets of paper are sent to the staple tray.
From now on until the end of the stack of paper to be stapled, paper is fed to the stapler two by two in this way.
