Make sure to set the SP provided on the metal plate of the main controller board after replacing the main controller board.
An EEPROM [A] is installed in the controller board to record the drive frequency and number of sheets. When the controller board is replaced, take the EEPROM off the old board and install it on the new one.
There is an EEPROM on the new main controller board, but this is not needed and can be discarded or kept as a spare part.

Overview
To achieve stable stacking of printouts and to prevent users from touching the printouts, paper exit guide [A] and paper exit guide cover [B] have been added.
Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
Drive
With the paper exit guide drive motor [A] and the timing belt, the paper exit guides on both sides move at the same time.
Home position is detected by the paper exit guide HP sensor [B].
Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
Location of the stapleless stapler unit
The stapleless stapler unit [A] is on the same shaft as the conventional stapler unit [B], which uses staples.
FINISHER SR3210/ BOOKLET FINISHER SR3220 (D3B8/D3B9)
The stapleless stapler unit is at the back and the conventional stapler unit is at the front. A spacer [C] on the shaft functions as a stopper, preventing the units from colliding.
Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
Paper stack mechanism for stapling
The maximum thickness of the stack is 50 sheets for the conventional stapler, and 5 sheets for the stapleless stapler.
In order for the stapleless stapler to stack the paper smoothly, cam [C] and paper guide [B] adjusts the gap [A] of the stapler tray [E].
The cam [C] controlled by the paper guide motor [D] pushes the paper guide [B] down during the stapleless staple operation.
Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
Stapleless stapler unit movement mechanism
The stapleless stapler transfer motor [A] moves the stapleless stapler unit to the stapling position from its home position when stapling with the stapleless stapler.
The home position is detected by the stapleless stapler HP sensor [B].
FINISHER SR3210/ BOOKLET FINISHER SR3220 (D3B8/D3B9)
The stapler transfer motor [C] and the stapler HP sensor [D] are attached to the base plate.
There is a gap at the paper guide when the stapleless stapler unit is at the home position when stapling with the conventional stapler.
Because of this, paper will be guided with the paper guide [B] which works together with the lever [A] when the stapleless stapler unit moves to its home position.
Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
Stapleless Stapler mechanism
The staple operation in this option applies a crimping method. V-shaped teeth press the sheets, applying a pressure of 220 kg.
This option performs two stapling operations for a single stapling operation as follows. [Moving to the first stapling position =>Stapling => Moving to the second stapling position => Stapling => Moving back to the home position]
Stapling is done by engaging the pressure cam [D] to stretch the pressure link [A], which applies pressure between to the upper tooth [C] and the lower tooth [B]. Moving and stapling operation for the stapler are driven by the stapler drive motor. The home position is detected by the stapleless stapler HP sensor.
Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
Double/Single
The bond strength depends on the degree of entwining of fibers between sheets of the paper bundle. Setting to Single or Double stapling allows you change the bond strength. Single applies one staple operation.
FINISHER SR3210/ BOOKLET FINISHER SR3220 (D3B8/D3B9)
Double applies one more, with the same operation as the first staple, at 4mm from the first. The stapleless stapler drive motor moves the paper after the first stapling.
Bundle ejection
After stapling, the trailing edge presser is released. The bundle of paper is ejected by the paper output roller.
Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
Stapler movement mechanism
This stapler needs to staple twice for a single staple position, and must be moved to do this stapling.
A cam [A], which is located in the stapler unit and has a groove on the body, and a securing pin perform the moving operation when stapling.
The moving and stapling is done by the stapleless stapler drive motor [B] and the home position is detected by the stapler HP sensor [C].

FINISHER SR3210/ BOOKLET FINISHER SR3220 (D3B8/D3B9)
The movement differs between Single and Double stapling.
[A]: Paper
[B]: Stapleless stapler unit [P1]: Pre-stapling position
[P2]: Stapling position 1 (Single) [P3]: Stapling position 2 (Double) [P4]: Home position
Single stapling operation
The stapleless stapler unit is at the home position before receiving paper.
The stapleless stapler unit moves to the pre-stapling position when starting a stapleless stapling job.
Booklet Finisher SR3220 / Finisher SR3210 (D3B9/D3B8)
After receiving the first sheet, the stapleless stapler unit moves from the Stapling Position 1 towards the rear by 2.2 mm. After stacking the sheets, stapling is performed. (Stapling Position 1)
When stapling on multiple copies, the stapleless stapler unit moves towards the front by 2.2 mm from the pre-stapling position after the paper is delivered.
When stapling on multiple copies, Steps 3 and 4 are repeated.
The stapleless stapler unit returns to the home position after completing the job.
