B. Gate /Up
The gate /Up [5] switches the paper path of the paper that was conveyed to the upper conveyance path by the
gate /Lw. The gate /Up is set to the paper path to the exit side [3] when the gate solenoid /Up (SD2) [4] turns
OFF [6]. The gate /Up is set to the paper path [2] to the 1st folding stopper [1] when SD2 turns ON [7].

C. Operation timing
(1) Z-folding mode
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 edge sensor board (PESB) detects the leading edge of the paper [1], and then 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.
SD1 and SD2 turn OFF [2] a specified period of time after the last paper turns OFF the exit sensor (PS9).
