There are two types of original detection in this equipment.
1. Original Presence / Absence Detection
Detected by DS (Document Sensor: PS106)
Setting the original onto the original tray pushes up the actuator, activating (light shielded =>light transmitted) the DS (PS106), and resulting in detection of the
presence of original.
2. Detection of the End of the Original
Detected by the DES (Document End Sensor: PS105)
The leading edge of the original that is fed pushes up the actuator, activating the DES (PS105) (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 (PS105) (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.
MEMO:
There is no function to detect the original size (original width, length) in this equipment.
