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 transport roller [E] by the paper feed belt [D], and then fed to the vertical transport unit.
Air blown from the separation fan and float fan is switched on/off by the shutter [F].
The air blown from the side air nozzles assist float and suction of the next sheet of paper. Also, it prevents double feed.
The return fan [A], return fan shutter [B], and return solenoid [C] near the feed nozzle improve the separation quality. Additionally, in the feed belt unit, the suction fan shutter [D] and suction fan shutter solenoid [E] prevent paper scratches during paper feed by the belt, by controlling the suction on the belt.
The three feed belts are installed at the same level. This improves the suction power and the feed quality for long paper.
