9) Start of 2nd original back side scanning
Scanning begins after receiving the original transport signal from the engine. At the same time the
original stop signal is reset. The read motor (M36) starts to rotate forward and the large original exit
motor (M39) starts to rotate in reverse.
The SCN-STR turns ON when the leading edge of the original has reached the scanning section,
and the large original exit solenoid (SOL5) turns ON, too. The large original exit motor (M39) starts
to accelerate when the trailing edge of 1st original has passed the 3rd roller and proceeded a speci-
fied distance.
When the leading edge of the original has been transported to the large original exit side and come
to the 3rd roller, the large original exit roller release solenoid (SOL6) turns ON. The large original exit
motor (M39) starts to slow down when the trailing edge of 1st original has passed the intermediate
transport roller.
The SCN-STR turns OFF when the trailing edge of the original has passed the scanning section. At
the same time, both the read and the large original exit motors (M36, M39) start to accelerate and
the large original exit roller release solenoid (SOL6) turns OFF.
When the trailing edge of the original has passed the 4th roller then proceeded a specified distance,
the large original exit motor (M39) starts to slow down. After the large original exit sensor (S68) has
detected the trailing edge of the original, the read motor (M36) stops rotating soon and the large
original exit motor (M39) stops rotating when the original has proceeded a specified distance. The
large original exit solenoid (SOL5) turns OFF when the large original exit motor (M39) stops rotating.
