Staple-free Staple Operation

■ Outline
When staple-free stapling is specified, the paper stack that is center-aligned by the processing tray is moved to the staple-free
stapling position by the front alignment plate and assist guide. The paper stack is clinched by the clinch arm.
The clinch arm's home position is detected by the clinch HP sensor (PS15).
After power ON, the finisher controller PCB drives the clinch motor (M9) to return the clinch arm to the home position. If the clinch
arm is at the home position to begin with, it remains there and waits.
Clinch errors are detected using clock pulses from the clinch motor drive detection sensor (PS13).
The staple-free staple unit is fixed in place in the rear of the finisher. Only a single stapling position is used, which is at the rear.
Stapling at four locations (upper left, upper right, lower right, lower left) is possible using the host machine's LUI through image
processing of the printed surface.
After staple-free stapling, the paper stack is delivered by the assist guide.
