Adjustment
05 Z-Fold Position Adjustment
Perform this adjustment for the folding positions in Z-Fold mode processed
by the Folding Unit FD-501.
Reminder
When adjusting both Single Fold and Double Fold, be sure to start with
the Single Fold adjustment.
The baseline of Single Fold is calculated from the edge of the sheet, while
that of Double Fold is calculated from the position of the first fold line,
therefore a distance (b) in step 5 will be altered by changing the position
of either Single Fold or Double Fold.
