[Addition]

Screw locking agent

* 4406361350 BOND-1401E
* At the time purchase each can contains 1kg which is

quite a lot to carry around with you, so you should divide
up the amount into smaller containers.

Note

1.24 Fine Adjustment of Binding Position/Folding Position
[Addition]

By moving the paper positioning plate up or down, fine adjustment of the binding position/folding
position can be made.

BSI No. F99D591 Page 3

Adjustment Code "05" - Code "468-0~2"

* Increasing the adjustment value shifts the binding position/folding position towards the right-hand
page by 0.25mm for each/step.
* Decreasing the adjustment value shifts the binding position/folding position towards the left-hand
page by 0.25mm for each/step.

* When fine adjustment of the binding position/folding position is performed, the following result
should be obtained.
* When a book is made, to have it opening from the right: page 1 (see figure A below).

1.25 Adjustment of RADF Height
[Addition]

The adjustment screws attached to the hinge are to adjust the height of the gap between the glass
and the RADF.
(1) Adjustment screws:

If they are turned counterclockwise, the gap becomes narrower.
The adjustment screws are on the right hinge and the left hinge (2 places).

(2) The gap (arrow A) of the adjustment value is 0 ~ 0.5mm.

(3) Fix BRKT-SOL-RVS with the screw.
(4) With the solenoid pulled out, confirm that there is no gap between the flapper rubber and the
flapper lever.
