The ADF is a feeding device used exclusively for stream reading, and its series of operations (original pickup, feeding, delivery) is performed using the drive of
the ADF motor (M2001).
An original picked from the original placement assembly is controlled so that its movement will match the read start timing of the host machine's contact sensor.
Then, the original is moved as far as stream reading position, read by the contact sensor (for collection of analog image data), and sent to the delivery assembly.
The ADF has 4 sensors to monitor the state of the original. The names and the functions of the sensors are as follows:
T-4-1
F-4-1
