closed.
• (2) Clamp Roller - Retracting. Opened and closed by the
retraction motor [C].
[C] Clamp Roller Retraction Motor. Operates the clamp roller cam
that retracts the retracting clamp roller. The clamp rollers feed the
stack to within 3 mm of the bottom fence when closed and then
open to drop the stack onto the bottom fence.
[D] Clamp Roller HP Sensor. Controls the rotation of the clamp
roller retraction motor and cam that open and close the retracting
clamp roller.
[E] Clamp Roller Cam. Forces open the spring loaded retracting
clamp roller.
Bottom Fence
[F] Bottom Fence. Raises the booklet stapled stack to the fold posi-
tion.
[G] Bottom Fence HP Sensor. Detects the actuator on the bottom
fence and stops it at the home position after folding.
[H] Bottom Fence Lift Motor. Raises the bottom fence and stapled
stack to the fold position prescribed for the paper size.

Fold Plate
[A] Bottom Fence Stack Stoppers. Catches the stack after it is
released by the clamp rollers.
[B] Fold Plate Motor. Drives the timing belt and gears that move the
fold plate.
[C] Fold Plate Cam. Controls the movement of the fold plate to the
left (into the nip of the fold rollers) and right (toward the fold plate
home position).
[D] Fold Plate HP Sensor. Controls operation of the fold plate
motor.
[E] Fold Plate. Moves left and pushes the stack into the nip of the
fold rollers and then moves right to retract.
Fold Rollers
[F] Fold Roller Motor. Drives forward to feed out the stack at the
fold and then reverses to feed the fold in to sharpen the crease,
and then drives forward again to feed out the folded stack. This
reverse/forward cycle is done once.
[G] Fold Rollers. Driven by the fold roller motor, this roller pair feeds
out the stack at its fold, reverses to feed in the stack to, and then
feeds forward again (assisted by the fold unit exit rollers - not
shown) to feed out the stack to the booklet output tray.

The PWB’s of this model employs lead-free solder. The “LF” marks indicated on the PWB’s and the Service Manual mean “Lead-Free” solder.
The alphabet following the LF mark shows the kind of lead-free solder.
(1) NOTE FOR THE USE OF LEAD-FREE SOLDER THREAD
When repairing a lead-free solder PWB, use lead-free solder thread.
Never use conventional lead solder thread, which may cause a breakdown or an accident.
Since the melting point of lead-free solder thread is about 40°C higher than that of conventional lead solder thread, the use of the
exclusive-use soldering iron is recommended.
exclusive-use soldering iron is recommended.
(2) NOTE FOR SOLDERING WORK
Since the melting point of lead-free solder is about 220°C, which is about 40°C higher than that of conventional lead solder, and its soldering
capacity is inferior to conventional one, it is apt to keep the soldering iron in contact with the PWB for longer time. This may cause land
separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when
completion of soldering is confirmed.

separation or may exceed the heat-resistive temperature of components. Use enough care to separate the soldering iron from the PWB when
completion of soldering is confirmed.
Since lead-free solder includes a greater quantity of tin, the iron tip may corrode easily. Turn ON/OFF the soldering iron power frequently.
If different-kind solder remains on the soldering iron tip, it is melted together with lead-free solder. To avoid this, clean the soldering iron
tip after completion of soldering work.
tip after completion of soldering work.
If the soldering iron tip is discolored black during soldering work, clean and file the tip with steel wool or a fine file.
