6964 Length Adjustment (Folder)
These SP codes adjust the length of the folds. The summary below describes
important terms used in these SP descriptions. For more see the “Folder FD
6500 Service Manual.”
There are two types of folding:
! Long folding . The folded copy looks like an accordion with the edges of the folded
surfaces aligned.
! File folding . The same as long folding but the leading edge of the bottom sheet
protrudes from the bottom of the stack. This margin can be used to fasten the leading
edge into a flat binder, or it can be punched for filing in a ring binder.
The first example [A] is a long fold. The second example [B] is a file fold. The colored
arrows show the direction of paper feed when viewed from the right side of the folder unit.
For the sake of convention, the folds on the right sides of the stacks shown above are
called “peak folds” and those on the left are “valley folds.” In Stack [A], fold is a peak
fold, fold is a valley fold, is a peak fold, and so on.
! In a “long fold” like Stack [A], the first fold is always a peak fold.
! In Stack [B], is the leading edge fed wider than other sections of the stack, is a
valley fold, is a peak fold, is a valley fold, and so on.
! In a “file fold” like Stack [B], the first fold is always a valley fold (done after creating the
longer bottom sheet with the protruding leading edge). To create this difference in
length, the fan fold motor feeds the leading edge to the rear slightly farther (about 40
mm) than the other folded sections above.
