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

6-2. Paper Switchback Mechanism
• When the last paper of the first copy set is transported onto the Finisher Tray during a
multi-copy cycle in the Sort Staple mode, the first paper of the subsequent copy set,
which is to be next transported, undergoes a switchback sequence. The paper for the
switchback is transported via the lower paper path.
• The second paper of the second copy set is placed over the paper which has undergone
the switchback sequence. After the first copy set has been fed into the Elevator Tray, the
first and second sheets of paper of the second 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.
• No switchback sequence is carried out if the interval between sheets of paper is wide as
when using paper of a large size.

➀
: Sheets of paper for the first copy set
’, ➁’, ➂’: Sheets of paper for the second

4643M027AD
The sheets of paper for the first copy
are transported via the upper paper
path onto the Finisher Tray.
4643M031AH
The first sheet of paper of the second
copy set is transported via the lower
paper path.
4643M028AG
The first sheet of paper of the second
copy set undergoes the switchback
sequence and stops. The second
sheet of paper stops as soon as its
trailing edge leaves the Entrance
Roller.
4643M029AG
The first and second sheets of paper
of the second 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 first copy set out. At the same
time, the first and second sheets of
paper of the second copy set are
transported toward the exit.
4643M032AE
When the first copy set is fed out, the
Exit Roller starts turning backward to
transport the first and second sheets
of paper of the second copy set to the
Finisher Tray. The Exit Rolls leave the
Exit Roller.

6-3. Roller/Rolls Spacing Mechanism
(1) Storage Roller/Rolls Spacing Mechanism
• The Storage Roller briefly stops when the first sheet of paper completes a switchback
sequence during a multi-copy cycle in the Sort Staple mode. If, however, paper measures 217 mm or more in the FD direction, the leading edge of the second sheet of paper
reaches the Storage Roller before the roller stops turning. The Storage Roller is therefore
raised up to allow a given clearance from the Storage Rolls.
• The Storage Roller is spaced from the Storage Rolls as a cam is turned by the corresponding motor.
(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 cam which is rotated by the motor.
