Booklet stitching mechanism
Paper which has been stitched in the center is pressed in by the booklet stitch folding roller with the folding blade.
The paper folded by the folding roller is released by the paper exit shutter, and is stacked in the booklet tray one sheet at a time.
A compact layout is achieved by sharing the edge binding stapler, booklet tray, transport, and stack.
The stapler unit and the folding process unit are divided.
Booklet stitch bundle transport and pressure release
In the case of booklet stitching, the paper must be transported to the stapling position. Booklet transport rollers are provided at two positions, upper and lower. The transport and timing of the rollers which transport the bundle differ according to the paper size.

Folding blade operation
The binding position is pressed by the movement of the folding blade, and pushed in until the folding roller grips.
The movement is performed by front and rear folding cams, and the folding blade moves horizontally.
The rotation of the folding cam is controlled by the folding cam HP sensor, and the folding blade is controlled by the folding blade HP sensor.
This is driven by the folding blade motor.
Folding roller operation
The folding rollers apply pressure up and down by springs, and press the binding parts. When the stitching position reciprocates back and forth, the paper is folded again, and the paper is then ejected.
