Composition/Operation
B. Operation flow in the 2-sided mode
1. When the Start key is pressed, the Paper Feed Motor starts turning backward,
causing the Pick-Up Roller to lower and start feeding the 1st page of the document.
The scanning of the 1st side is started after the lapse of a given period of time after
the Original Detection Sensor has been activated by the leading edge of the 1st
page.
The Transport Motor is deenergized to stop the original after the lapse of a given
period of time after the trailing edge of the 1st page has deactivated the Exit/Turn-
over Sensor.
2. The Transport Motor is turned backward to turn over the original. After the Registra-
tion Roller, the Transport Motor is turned forward to allow the Scanner to scan the
backside of the 1st page.
3. After the transport sequence for turnover has been started, the Exit Roller Retrac-
tion Solenoid is energized so that the Exit/Turnover Roller is retracted.
