Double Folding Operation - Canon SADDLE FINISHER K3 Service Manual

12.5.4 Double Folding Operation

When 10 or more sheets of A4R or LTR-R size paper are to be folded, the paper is folded
by double folding.
After the paper stack has been drawn in about 20mm, the folding rollers rotate in reverse
for 20mm. This enables greater nipping force to be applied to the fold by the folding rollers.
The folding rollers then rotate forward to deliver the paper stack and the paper retaining
plate returns to the home position.
This operation ensures that several sheets of paper of a size that requires a strong folding
force can be folded properly.
1) The paper retaining plate pushes the paper in the direction of the folding rollers.
2) The folding rollers pull in the paper for approximately 20mm.
