(3)Finisher Tray Paper Transport Mechanism

•Paper transport to the Finisher Tray takes place when the Finisher is in the Staple mode.

•As the Lower Entrance Motor is energized, the Storage Roller turns to transport the paper toward the exit direction.

•By turning the Exit Motor backward, paper is transported onto the Finisher Tray.

•Either the upper paper path or lower paper path is used depending on the copy mode to transport the paper onto the Finisher Tray.

•The upper paper path is selected when the Upper/Lower Entrance Switching Solenoid is energized, while the 1st Tray Entrance Selecting Solenoid is deenergized.

•The lower paper path is selected when the Upper/Lower Entrance Switching Solenoid is deenergized.

PAPER TRANSPORT

1.2Paper Switchback Mechanism

•When the last paper of the 1st copy set is transported onto the Finisher Tray during a multicopy cycle in the Sort Staple mode, the 1st paper of the subsequent copy sets, which is to be next transported, undergoes a switchback sequence. The paper for the switchback is transported via the lower paper path.

•The 2nd paper of the 2nd copy set is placed over the paper which has undergone the switchback sequence. After the 1st copy set has been fed into the Elevator Tray, the 1st and 2nd sheets of paper of the 2nd copy set are together transported onto the Finisher Tray.

•The switchback sequence of the paper is performed by turning the motor backward, which turns the Lower Path Transport Roller and Storage Roller backward.

•The sheet of paper to be transported next to the one subjected to the switchback sequence is transported via the upper paper path.

The 1st sheet of paper of the 2nd copy set undergoes the switchback sequence.

4643M029AG

The 1st and 2nd sheets of paper of the 2nd copy set are transported together, one on top of the other.

4643M030AH

The Exit Rolls are pressed against the Exit Roller to feed the sheets of paper of the 1st copy set out. At the same time, the 1st and 2nd sheets of paper of the 2nd copy set are transported toward the exit.

4643M032AE

When the 1st copy set is fed out, the Exit Roller starts turning backward to transport the 1st and 2nd sheets of paper of the 2nd copy set to the Finisher Tray. The Exit Rolls leave the Exit Roller.

PAPER TRANSPORT

1.3Roller/Rolls Spacing Mechanism

(1)Storage Roller/Rolls Spacing Mechanism

•While in continuous copying in the Sort Staple mode, the Storage Roller stops once when the switchback of the 1st paper after the 2nd copy is completed. However, when the paper size is larger than 217mm, the 2nd paper reaches the Storage Roller. So, the Storage Roller is raised up to be separated from the Storage Roll.

•After the 2nd paper stops, the Storage Roller goes down and convey 2 sheets that are put one over another onto the process tray.

•The separation of the Storage Roller is made by rotating the cam through the drive of the motor and moving the lever to right and left.

(2)Exit Roller/Rolls Spacing Mechanism

•Paper needs to be temporarily transported to the Finisher Tray in the Staple mode, which makes it necessary to raise the Exit Rolls to provide a given clearance from the Exit Roller.

•After the stapling sequence has been completed, the Exit Rolls are lowered and pressed against the Exit Roller so that the paper can be fed out.

•The Exit Rolls are spaced from the Exit Roller as a lever is moved to the right and left by the corresponding motor.
