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

The stitch unit receives sheets from the finisher unit and outputs them inside the vertical path in

vertical orientation.

The vertical path, while sheets are being output, is configured by two paper deflecting plates.
The position of the sheets being output is set by the paper positioning plate so that the center of

the stack matches the stapling/folding position.

Sheets coming later are output closer to the delivery slot, and the volume of paper that may be

output is as follows:

●

15 sheets (maximum of 14 sheets of 80 g/m

2

 + 1 sheet of 256 g/m

The alignment plates operate to put the sheets in order each time a sheet of paper is output to

the vertical path assembly. The alignment plates are mounted at the edge of the vertical path assem-
bly.

The alignment plates also operate after stapling to prepare the stack for delivery.
