Air Assist Control
To facilitate separation of coated paper, this equipment executes air-assisted control. The
flotation fan (FAN101, FAN201, FAN301, FAN202, FAN302) blows air against the paper so
that the paper is shifted slightly to lose attraction, preventing double feeding.
MEMO:
Air-assisted control is performed in the same manner for all decks.

Air-assisted control is performed by the DC controller PCB of the host machine via the deck
driver PCB.
The air-assisted control items are listed below.
MEMO:
The flotation fan (FAN201, FAN301, FAN202, FAN302) and swing motor (M202, M302)
are also controlled in the same manner as the following flotation fan (FAN101, FAN102)
and swing motor (M102).
