SP6-xxx Peripherals
1 Fold Length: 1
This SP determines the start of the first peak fold. To do this, it changes the timing
of the fan fold sensor (F) that affects how far the paper feeds past this sensor
after the first peak fold. This adjustment determines the length of a flap at the first
fold wider than the succeeding folds.
[-70 to 70/0/0.1 mm]
Note:
! Adjustment in the "-" or "+" direction decreases or increases the amount of
paper that feeds past the sensor. This decreases or increases the length of
paper between the first two folds.
2 Fold Length: 1
This SP determines the start of the first valley fold. To do this, it changes the
timing of the fan fold sensor (R) that affects how far the paper feeds past this
sensor after the first peak fold. This adjustment determines the length of a flap,
starting at the leading edge, that is wider than the succeeding folds. (This
elongated flap can be used to bind the folded copy.)
[-70 to 70/0/0.1 mm]
Note: Adjustment in the "-" or "+" direction decreases or increases amount of
paper that feeds past the sensor. This decreases or increases the length of the
paper (section) from the leading edge to the first valley fold.
3 Fold Length: 2
This SP adjusts the operation of the fan fold sensor (F).
! If the first fold is a peak fold, this SP setting determines the length of even
number sections, excluding that of the first section.
! If the first fold is a valley fold, this SP setting determines the length of odd
sections.
Note: Adjustment in the "-" or "+" direction decreases or increases amount of
paper that feeds past the sensor. This decreases or increases the length of the
even or odd sections.
