Original Detection
There are two types of original detection in this equipment.
1. Original Presence / Absence Detection
Detected by DS (Document Sensor)
As the actuator is pushed up by placing an original on the Original Tray, DS of SADF is
turned ON(light is blocked =>light is transmitted) and DS of DADF is turned OFF (light is
transmitted => light is blocked) so that presence of an original is detected.
2. Detection of the End of the Original
Detected by the DES (Document End Sensor)
The leading edge of the original that is fed pushes up the actuator, activating the DES (light
shielded =>light transmitted) and resulting in detection of the reach of the leading edge of
original. Furthermore, when the trailing edge of the original passes the actuator position,
the actuator returns to the original position, inactivating the DES (light transmitted => light
shielded). The trailing edge of the original is detected by this mechanism. The original
length that can be scanned with this equipment is less than 400 mm. Passing of the original
longer than this results in jam stop. The original length is calculated by the time it takes
from detection of the leading edge of the original to detection of the trailing edge of the
original.
Note:
There is no function to detect the original size (original width, length) in this equipment.
