3. Maintenance of controlling part
3.1 Structure of controlling part
The controlling part is mainly composed of the controller part which is performing the
screen display and the data management, the engine part performing the print and the
circulation system control, I/O part performing the external signal control, and interior of
inlet cover at primary power side.
Be sure to turn OFF the power when you open the cover of the controller part, the
engine part and I/O part. And then wait for 10 seconds at least before accessing
those parts. Be careful against the electric shock when you perform adjustment with
the cover opened since the high voltage is applied in the unit.
