Folding transfer control

• The folding transfer motor drives the folding roller.
• Then, the folding roller drives the tri-folding roller.
A. Folding transfer control
• The folding knife motor turns ON [2] after a specified period of time since the folding pas-
sage sensor detects the paper and the saddle stitching stopper stops at the folding posi-
tion.
• When the folding knife motor turns ON the folding knife home sensor, the folding transfer
motor turns ON [3] and drives the folding roller to perform the 1st folding and the tri-fold-
ing roller to perform the 2nd folding at the tri-folding operation, and then it exits the paper
to the finishing tray3.
• The folding transfer motor stops after a specified period of time since the folding paper
exit sensor detects the trailing edge of the paper bundle.
