Ricoh Neptune-P1, Service Manual

Page: 348 / 457

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.
As shown in Stack [A] above, the top flap is slightly shorter than the other folds below which are of uniform
size. If this is not desirable, the folding job can be set to calculate how much paper is needed for the last
fold to ensure that the top flap is the same length as the other folds below, with folded surfaces of shorter
length hidden in the stack. The folds of the paper remaining before the final full-length fold are "adjusted"
