Folding transfer control

The folding transfer motor (M20) drives the folding roller. Then, the folding roller drives the tri-folding roller.
A. Folding transfer control
The folding knife motor (M19) turns ON [2] after a specified period of time since the folding pass-through sensor
(PS26) detects the paper and the saddle stitching stopper stops at the folding position. When M19 turns ON the
folding knife home sensor (PS22), the folding transfer motor (M20) turns ON [3] and drives the folding roller to
perform the 1st folding and the tri-folding roller to perform the 2nd folding at the tri-folding operation, and then it
exits the paper to the booklet tray.
M20 stops after a specified period of time since the folding paper exit sensor (PS25) detects the trailing edge of
the paper bundle.
