2.2 BASIC OPERATION
2.2.1 ORIGINAL SET AND SIZE DETECTION
The original set sensor [A] detects if the original is set or not. The original sensor [B]
detects if the original is on the original tray or not (this lets the machine know as early as
possible, whether there is another original on the tray).
The original size detection mechanism consists of the four original width sensors ([F]: Width
Sensor S, [G]: Width Sensor M, [H] Width Sensor L, [I]: Width Sensor LL) and three original
length sensors ([C]: Length Sensor S, [D]: Length Sensor M, [E]: Length Sensor L). Based
on the combined output of the length sensors and the width sensors, the machine can
detect the size of the original. This integrated detection mechanism is detailed in the table
below.
