Flattening a Fold (Strength): Adjusting the Spine Corner Forming Strength
Adjust the strength when forming the booklet spine using Folding Unit FD-504 mounted in Saddle Stitcher SD-513.
This function allows you to adjust the reference value of the spine corner forming strength (Strong+, Strong, Normal, Weak, or Weak+) to be specified on the [COPY] screen or using the printer driver.
For example, if the strength is set to the Strong direction in this adjustment, the reference value of the spine corner forming strength totally shifts to the Strong direction.
If the strength specified on the [COPY] screen or using the printer driver is insufficient, you can specify a stronger strength in this adjustment, but be careful that the reference value shifts totally.
For example, if the strength is set to the Weak direction in this adjustment, the reference value of the spine corner forming strength totally shifts to the Weak direction.
