When the fold rollers [1] feed the stack 10 mm past the nip, the fold plate retracts
until it no longer touches the stack. The fold unit exit sensor [2] detects the folded
edge of the stack and stops the fold rollers.
11
The rotation of the fold rollers [4] reverses and feeds the folded edge back until
only 3 mm of the fold [5] remains at the nip.

The fold rollers [6] rotate forward once again feed out. The fold unit exit sensor [7]
once again detects the edge of the fold.
NOTE: You can do SP6203 001 to increase the sharpness of the fold. The number
of forward and reverse feeds of the fold rollers can be set in the range of -1
to +28. The machine repeats Steps 11 and 12. For more, please refer to
Section "5 Service Tables*.
