The 1st fold roller [1] and 2nd fold roller [2] continue to turn. This feeds the edge of
the 1st fold up until it hits the upper stopper [3].
The sheet lifts the feeler of the upper stopper path sensor [4]. This sensor:
• Detects when the sheet comes to the upper stopper path.
• Detects when the sheet goes out of the upper stopper path.
The upper stopper sensor detects a jam if it does not detect that the sheet comes
and goes at the correct times.
When the sheet feeds between the 1st and 2nd fold rollers, this pushes the first
fold against the upper stopper. The sheet buckles down into the gap between the
2nd fold roller [5] and 3rd fold roller [6]. The second fold is made when the sheet
feeds between the 2nd and 3rd feed rollers.
