(Caution) When the setting exceeds 8.0 mm, the range that the corner knife cannot cut comes out.
The range is 4.1 mm to 5.9 mm as shown in (Fig. C).
This range corresponds to conditions i) and ii) and error message (E480/E481) of “Setting
that corner knife does not cut” is displayed on the panel as well. Please understand.

1) Adjust the long corner knife so that the cutting length of the outside knife becomes from 4.0 mm
to 6.0 mm.
For the actual adjustment procedure of the knife, refer to
"VII-8.(2) Adjusting the corner knife" p.
.
2) After the adjustment of the knife, it is necessary to change the setting of excess cut length ac

cording to the adjustment amount of corner knife since the initial values of the excess cut length
of index (
/
) are 4.0 mm respectively
Add 2.0 mm to the excess cut length and set the initial value 4.0 mm to 6.0 mm since the knife has
been adjusted so that the cutting length of the long corner knife becomes longer by 2.0 mm.
In the standard state of delivery, the deflection of corner knife can be used only up to 8.0 mm.
When desiring to perform the deflection setting of more than 8.0 mm, change the setting of deflec
