The pinch feed roller [1] feeds the sheet down against the lower stopper [2].
At the same time, these rollers turn:
• 1st fold roller [3]
• 2nd fold roller [4]
• 3rd fold roller [5]
The sheet continues to buckle until it feeds into the nip [6] of the 1st and 2nd fold
rollers. These two rollers fold the sheet.
The leading edge sensor [7] detects the leading edge of the sheet:
• When the leading edge goes by while the paper feeds down (to the lower
stopper).
• When the leading edge goes by again while the paper feeds up into the nip of
the 1st and 2nd fold rollers.
If the leading edge sensor does not detect the leading edge at the correct time, this
sensor signals a jam.
At the correct time, the pinch idle roller [8] is pulled away from the pinch feed roller
[9] by the pinch idle roller solenoid (upper).
