Original sizes are detected with the combination of a CCD and the automatic original detection sensors.
A size in the primary scanning direction is detected by the CCD while that in the secondary one is
detected by the sensors. 2 platen sensors (S28 and S29) serve to detect the platen cover (or the
RADF) position.
A
S28
S29
A: Platen cover (or RADF) fully opened
When the platen cover is fully opened, an original size is not detected.
B: Platen cover (or RADF) opened by 20 degrees – Detected by platen sensor-1 (S28)
When this status is detected, the exposure lamp of the scanner emits light. This emitted light is
reflected by the original and read to the CCD as original size data. A size in the primary scanning
direction can be detected by the intensity of the reflected light.
C: Platen cover (or RADF) closed – Detected by platen sensors-1 and -2 (S28 and S29)
When the platen cover is fully closed, this situation is detected by platen sensor-2.Then automatic
original detection sensors-1 and 2 detect a size in the secondary scanning direction (and the presence/
absence of an original by their positions).
As for the LT series, two automatic original detection sensors detect a size in the secondary scanning
direction due to the original size.
