12)Start of 2nd original back side scanning
Scanning begins after receiving the original transport signal from the engine. At the same time, the
original transport signal turns OFF. When the read motor (M36) starts to rotate forward, the large
original exit motor (M39) also starts to rotate forward and the large original exit roller release sole-
noid (SOL6) turns ON. 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 intermediate transport section
and come to a specified distance before the intermediate transport roller, both the large and small
original exit motors (M39, M40) start to rotate in reverse. (The small original exit solenoid (SOL4)
has been ON from 1st original.)
Both the SCN-STR and the large original exit roller release solenoid (SOL6) turn OFF when the trail-
ing edge of the original has passed the scanning section. The large original exit motor (M39) starts
to accelerate when the trailing edge of the original has passed the 3rd roller and proceeded a speci-
fied distance.
