Operation in the saddle stitch section

The center-binding mode binds a stack of paper at its center by stapling at two positions and then folds
in half again to exit it to the saddle tray. In this mode paper transported from the feeding section is
stacked on the stacker. The stacks of paper are aligned on the stacker and moved to the stapling posi-
tion together with the stacker. Then the moved stacks are fixed and stapled, and then moved to the fold-
ing position. Then they are folded with the folding blade and the folding roller. After this, the folded
stacks are again folded and exited to the saddle tray.

Paper transported from the junction box is then transported to the stacker with the transport roller, eject-
ing roller and assisting roller driven by the saddle transport motor (M16).
The junction box paper detection sensor (S26), transport path-2 sensor (S27), transport path-3 sensor
(S28) and ejecting roller sensor (S29) detect the passing of the paper.
When the ejecting roller sensor (S29) detects that paper has passed, the assisting roller solenoid
(SOL6) is turned ON to contact the assisting roller with the paper to transport it to the stacker.
