B. Gate /Up
• The gate /Up switches the paper path of the paper that was conveyed to the upper con-
veyance path by the gate /Lw.
• The gate /Up is set to the paper path to the exit side when the gate solenoid /Up (SD2)
turns OFF.
• The gate /Up is set to the paper path to the 1st folding stopper when gate solenoid /Up
turns ON.

C. Operation timing
(1) Z-folding mode
1. In the Z-folding mode for the all paper size, the gate solenoid /Lw (SD1) and the
gate solenoid /Up (SD2) turn ON when the paper size detect board (PSDTB)
detects the leading edge of the paper.
2. The gate /Lw is set to the upper conveyance path and the gate /Up is set to the
conveyance path to the 1st folding stopper.
3. The gate solenoid /Lw and the gate solenoid /Up turn OFF a specified period of
time after the last paper turns OFF the exit sensor (PS9).
