2.2.1 ORIGINAL SIZE DETECTION
The original size detection mechanism consists of the five original width sensors ([A]: Width
Sensor SS, [B]: Width Sensor S, [C] Width Sensor M, [D]: Width Sensor L, [E]: Width
Sensor LL) and three original length sensors ([F]: Length Sensor S, [G]: Length Sensor M,
[H]: 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.
