MECHANISM

1. Original Loading Mechanism

1) When the original is placed on the Original tray, the Original detection sensor is activated and the
original is automatically loaded on the AF unit.
2) The AF stripper solenoid activates to lower the Shutter and Original feed arm comes down to hold
the original.
3) The Image scanner LED turns ON to make shading compensation.
4) With the press of the START key, the Read pulse motor activates to rotate the Original pickup
roller and Original stripper roller to feed the original.
5) The original, if fed in multi-layer, is stripped into one sheet by the Stripper roller and Original
stripper pad.
6) As the original keeps feeding, the Original IN sensor detects the original and turns OFF the AF
stripper solenoid to raise the Shutter and Original feed arm.
7) After a given rotation of the Read pulse motor, the motor turns OFF to finish the Original loading
movement.
2. Original Scanning Mechanism
1) The Drum starts to rotate after the original loading action is completed. At the same time, the
Read pulse motor activates to rotate the Original pickup roller, Stripper roller and Exit roller to
feed the original through the AF unit.
2) At the same time, the Write pulse motor activates ON to feed the master material within the
Master making unit.
3) As the Write pulse motor activates for a given amount to send the master 2mm forward, the read
& write signal goes ON. The Image scanner starts to scan the original and the master-making is
also activated.
3) As the original is about to come out of the AF unit, the Original IN sensor detects the tail edge
of the original. After a given time from the detection of the original tail edge by the Original IN
sensor, the read & write signal turns OFF. The Image scanner LED turns OFF to end the original
scanning.
3) The Read pulse motor keeps rotating to eject the original.
4) After a given time, the Read pulse motor stops to end the scanning movement.
