Double Folding A Stack - Canon Saddle Finisher-T2 Service Manual

2.2.14 Double Folding a Stack

Folding is made twice for every sheet, to fold a set of copies consisting of 10 or more A4R or LTR-R sheets or to
fold a set of copies consisting of from 3 to 9 A3 or 279 mm x 432 mm (11" x 17") sheets.
The paper folding rollers rotate in reverse for an equivalent of 20 mm after gripping the stack for a length of 20 mm,
enabling the paper folding rollers to apply an increased degree of pressure along the crease on the stack. Then, the
paper folding rollers rotate normally, and the paper pushing plate returns to its home position while the stack is being
delivered.
This way, a stack requiring a large force may properly be folded with less pressure.
1) The paper pushing plate pushes the stack in the direction of the paper folding rollers.
2) The paper folding rollers grip the stack for a length of about 20 mm.
