9) Start of scanning
Scanning begins after receiving the original transport signal from the engine, and at the same time,
the original stop signal is reset. The read motor (M36) starts to rotate forward and so does the large
original exit motor (M39). Then the large original exit roller release solenoid (SOL6) turns ON. (The
large original exit solenoid (SOL5) has been ON since the original was idle reversed.)
The SCN-STR turns ON when the leading edge of the original has reached the scanning section.
When the leading edge of the original is transported to the large original exit and reaches the 3rd
roller, the large original exit motor (M39) starts to rotate in reverse.
When the trailing edge of the original has passed the scanning section, the SCN-STR turns OFF,
and at the same time, both the read and large original exit motors (M36, M39) start to accelerate.
Then the large original exit roller release solenoid (SOL6) turns OFF.
With a next original, feeding of the original begins when the trailing edge of the original has passed
the 4th roller.
The large original exit motor (M39) starts to slow down when the trailing edge of the original has pro-
ceeded a specified distance after passing the 4th roller. At the same time, the read motor (M36)
stops rotating unless there is a next original.
The large original exit motor (M39) stops rotating when the trailing edge of the original has pro-
ceeded a specified distance after being detected by the large original exit sensor (S68). Then the
original is discharged.
If this is the last original, the operation ends when the large original exit solenoid (SOL5) turns OFF.
