The vacuum fan [A] holds the printed paper against the transport belts [B]. The transport
belts move the paper to the delivery table. The wing guides [C] located at the end of the
vacuum unit decrease the stains on the reverse side of the printing paper.
When the main motor turns on, the gear [F] mounted on the motor shaft drives the belts
[B] through gears [G], [H], [J], pulley [K], and the drive belt [1].
The first and second paper exit sensors check the paper feed condition.
Paper exit jam check occurs when the printing pressure is applied and the printing
pressure sensor is interrupted.
