The stitch unit aligns the sheets coming from the finisher unit and stitches the resulting stack for

delivery to the delivery tray according to the commands coming from the finisher controller PCB.

The machine’s operation consists of the following:

1. Receive sheets.
2. Aligns the sheets
3. Stitches the stack.
4. Feeds the stack.
5. Folds and delivers the stack.

1) Receive sheets

4) Feeds the stack

3) Stitches the stack

5) Folds and  
    delivers the stack

2) Aligns the sheets
