THEORY OF OPERATION

After publication of this service manual, the parts and mechanism may be subject to change for
improvement of their performance.
Therefore, the descriptions given in this service manual may not coincide with the actual machine.
When any change has been made to the descriptions in the service manual, a revised version will be
issued with a revision mark added as required.
Revision mark:
• To indicate clearly a section revised, show to the left of the revised section.
A number within represents the number of times the revision has been made.
• To indicate clearly a section revised, show in the lower outside section of the correspond-
ing page.
A number within represents the number of times the revision has been made.
NOTE
Revision marks shown in a page are restricted only to the latest ones with the old ones deleted.
• When a page revised in Ver. 2.0 has been changed in Ver. 3.0:
The revision marks for Ver. 3.0 only are shown with those for Ver. 2.0 deleted.
• When a page revised in Ver. 2.0 has not been changed in Ver. 3.0:
The revision marks for Ver. 2.0 are left as they are.

4.1 Horizontal transport mechanism
4.1.1 Paper path switching mechanism
• The path along which the paper is transported is selected with the Entrance Switching
Solenoid.
• During a 2-sided print mode, the solenoid is energized to feed the paper into the lower
path and then feed it back to the main unit.
• In a 1-sided print mode, and when a 2-sided printed page is fed in the 2-sided print
mode, the Entrance Switching Solenoid is deenergized so that the paper can be trans-
ported to the Finisher.

4.1.2 Finisher paper transport mechanism
• Drive from the Transport Motor turns the Transport Roller to transport paper fed from the
main unit onto the Finisher.
• The Transport Roller on the Finisher side is driven by the Transport Motor to feed the
paper through the Finisher.

• In the Non Sort Mode, Paper is taken back onto the Finishing Tray and then fed out onto
the Elevator Tray.

4.2.2 Sort mode
• In the Sort Mode, Paper is taken back onto the Finishing Tray and shifted to the front or rear side with
the Aligning Plate. Then, a stack of paper per set is fed out onto the Elevator Tray.
• However, even if printing has not been completed for all sets of prints, when 10 sheets for the large
size whose length is longer than 300mm or 30 sheets for the small size whose length is shorter than
299mm are stacked, a set of sheets is fed out onto the Elevator Tray.
Paper Transport
4.2.3 Staple Mode
• In the Staple Mode, when one complete set of prints is fed out onto the Finishing Tray,
stapling is performed. A stack of stapled paper is then fed out onto the Elevator Tray.

4.2.4 Center staple booklet mode
• In Center Staple Booklet Mode, A stack of paper fed onto the Finishing Tray is stapled (at
two places) and then transported to the Saddle Section.
• The paper transported to the saddle section is folded, and then fed out onto the Booklet
Tray.
• The maximum number of the Center Staple Booklet is ten sheets.

4.2.5 Paper stacking with finishing tray
• After the paper has been fed through the Exit Roller, the paper drops onto the Finishing
Tray. Then, the Paddle taps the top of the paper twice (once for the additional sheets) so
that the trailing edge of the paper reaches the Finishing Tray Stopper.
• After Paddle operation is finished, Swing Guide will be lowered to prevent curling of
paper.
• The Paddle Motor provides the drive for the Paddle and Its home position is detected
with the Paddle Home Position Sensor.

4.2.6 Aligning mechanism
• Two Aligning Plates are moved by drive of the Front, or Rear Aligning Motor in the for-
ward or reverse direction.
• The Aligning Plates home position is detected with the Front, or Rear Aligning Plate
Home Position Sensor. With reference to this home position, the amount of movement of
the Aligning Plate is determined.
