8) Start of 1st original back side scanning
Scanning begins after receiving the original transport signal from the engine. At the same time, the
original transport signal is reset. When the read motor (M36) starts to rotate forward, the large origi-
nal exit motor (M39) also starts to rotate forward and the large original exit roller release solenoid
(SOL6) turns ON. (The large original exit solenoid (SOL5) has been ON from 1st original.)
The SCN-STR turns ON when the leading edge of the original has reached the scanning section.
The large original exit motor (M39) stops when the large original exit roller release solenoid (SOL6)
has turned ON.
When the leading edge of the original has been transported to the large original exit side and come
the 3rd roller, the large original exit motor (M39) starts to rotate in reverse.
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 large original exit motors (M36, M39) start to accelerate and the
large original exit roller release solenoid (SOL6) turns OFF.
The large original exit motor (M39) slows down when the trailing edge of the original has passed the
4th roller and proceeded a specified distance. 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. Then the original
is nipped by the large original exit roller.
