Scanning starts after receiving the original transport signal from the engine. At the same time, the
original stop signal is reset. 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 solenoid
(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 rotating 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, the large original exit
motor (M39) starts to rotate in reverse and the small original exit motor (M40) also starts to rotate in
reverse and the small original exit solenoid (SOL4) turns ON.
Feeding of the next original starts when the read motor (M36) has counted a specified time since the
start of the scanning operation.
The SCN-STR turns OFF when the trailing edge of the original has passed the scanning section. At
the same time, the large original exit roller release solenoid (SOL6) also turns OFF.
The next original reaches the scanning waiting position and stops before the trailing edge of the
original passes the 3rd roller.
