● Two-fold operation sequence
When a post handling specification signal “Two-fold Operation” is received during copying, two-fold operation starts. The two-
fold operation sequence is as follows:
1. Registration correction
2. Paper feeding operation
3. Folding operation
4. Delivery operation
[Operation]
1. Registration correction
• The inlet motor 1 (M5), inlet motor 2 (M12), and outlet motor 2 (M13) drive at the same speed with the host machine.
• The Through/Fold Branch Solenoid (SOL2) turns on.
• The folding feed motor (M11) turns at a speed of 400 mm/s.
• The C-fold stopper motor (M9) turns at a speed of 533 pps and the leading edge pushing guide drives at a speed of 67
pps to move the Trailing edge stopper.
• When the paper has been fed 233.0 mm since the slowdown timing sensor (S30) turned on, the drive speed of the inlet
motor 1 (M5) and inlet motor 2 (M12) change to 650 mm/s. The folding position adjustment feed clutch (CL3) turns on.
• For plain paper, the inlet motor 1 (M5) and inlet motor 2 (M12) stop (amount of the registration loop: 7 mm) when the
paper has been fed 17.6 mm since the release timing sensor (S31) turned on. For thin paper, the inlet motor 1 (M5) and
inlet motor 2 (M12) stop (amount of the registration loop: 8.5 mm) when the paper has been fed 19.1 mm since the
release timing sensor (S31) turned on.
