DETAILS
SM 23 B660
Z-Folding Unit
B660
The 2nd and 3rd fold rollers [1] continue to turn and feed the sheet down.
The feeler of the upper stopper path sensor [2] falls and the sensor detects that the
sheet is gone. The fold rollers feed the folded sheet to the lower exit rollers [3].
The lower exit sensor [4] detects the leading edge and trailing edge of the sheet. If
the trailing edge is not detected during the correct time interval, the sensor detects
a jam.
The grip rollers [5] feed the folded sheet to the four pairs of vertical feed rollers [6].
The upper exit sensor [7] detects the leading edge and trailing edge of each folded
sheet. If the leading and trailing edge are not detected during the correct time
interval, this sensor detects a jam.
The upper exit rollers [8] feed the folded sheet into the finisher.
At the correct time:
• The upper stopper motor lifts the upper stopper [9] until the upper stopper sensor
[10] detects that the upper stopper is at its home position. This stops the motor.
• The lower stopper motor lowers the lower stopper [11] until the lower stopper
sensor [12] detects that the lower stopper is at its home position. This stops the
motor.
