Scanning starts after receiving the original transport signal from the copier. At the same time, the
original stop signal is reset. The read motor starts to rotate forward and to separate 2nd original.
When the leading edge of the original has reached the scanning section, both the SCN-STR and the
large original exit solenoid turn ON.
When the leading edge of the original has been transported to the large original exit side and reached to
the 3rd roller, the large original exit motor starts to rotate in reverse .
The SCN-STR turns OFF after the trailing edge of the original has passed the scanning section, and at
the same time, both the read and large original exit motors start to accelerate. After the trailing edge of
the original has passed the 4th roller and proceeded a specified distance, the large original exit motor
slows down.
After the large original exit sensor has detected the trailing edge of the original, the read motor stops
rotating soon and the large original exit motor stops rotating when the original has proceeded a specified
distance. Then the original is nipped by the large original exit roller.
