Air Paper Feed Mechanism

The air paper feed mechanism uses the air produced by the seven fans (float fan / separation fan / side

fan (front/rear) / return fan / suction fan 1, 2) to handle and lift up and separate paper during the

process of feeding paper.

The sheet separated is transported into the vertical transport unit while being sucked to the paper feed

belt unit.

The air produced by the float fan floats up paper from the stack through the four float air nozzles [A] at

the front of the paper feed tray. Also, air produced by the side fans blows through the side air nozzles

[B] at the side fences. Then the air from the separator air nozzle [C] at the front of the paper feed tray

separates the 1st sheet of paper from the 2nd sheet of paper.

The 1st sheet of paper separated is sucked against the paper feed belt [D], and is transferred to the
