1. Theory of Operation

1. Original Loading Mechanism

An original placed on the Original rack Is automatically fed when the master making process is started.

1. Shading Compensation

> When the Original IN sensor detects the original, the LED of the Image scanner turns ON and the shading compensation takes place.

2. Original Loading

> After the shading compensation is done, the Read pulse motor Activates to start feeding the original by rotating the Pickup roller and Load roller.

> The original put on the Original rack is fed into between the Image scanner and the white Shading sheet. Then the original is fed towards the Eject roller upper and lower.

> The Eject roller upper and lower ejects the original out.

2. Original Scanning Mechanism

When the master removal is completed, the Read pulse motor turns ON to feed the original onto the Image scanner.

And after completing the master removal, the Drum rotates to place the master onto the Drum until the Original scanning ends. Then original loading movement is completed.

1. Read pulse motor

> The Drum comes back to the position-A after the master removal is completed, the Read pulse motor activates to rotate the Load roller and Eject roller to feed the Original and to eject.

> The Read/Write start signal turns ON and the image scanning is started by the Image scanner.

2. Original IN sensor

> After the tailing edge of the Original clears out from the Original IN sensor, the Read/Write start signal and the Image scanner LED are turned OFF to stop the image scanning.

> The Read pulse motor stops after the original scanning movement ends.
